Selecting equipment for processing tires into crumbs: prices and characteristics of plants, lines and machines. Types of machines and technology for processing car tires Do-it-yourself rubber shredder

Every year, thousands of tires are lost in landfills and landfills, despite the fact that for an enterprising person they are free resource, from which crumb rubber can be produced.

If you need it only once, you can buy it in the required quantity from the manufacturers.

But where can you get crumb rubber if you need it on an ongoing basis and in large quantities?

It's worth thinking about purchasing your own.

However Not everyone can afford a full installation, and not everyone will find such an investment profitable. The solution is to create equipment with your own hands and use it to produce crumb rubber from tires at home.

If you need very little raw material, you can do without equipment at all.

To do this you will only need scissors and cutter.

The metal cord is first removed from the tire, then divided into strips and crushed into smaller fractions to the required size.

At this point the process is considered complete.

The material for decorating paths, flower beds or a separate playground is ready for use.

But in order to obtain a larger volume of raw materials or to have income from processing tires at home, you need the appropriate equipment.

Construction of a tire crusher

There are three main methods for producing crumbs:

Crushing tires after cooling them with liquid nitrogen to –190 degrees.
Production of crumbs using full-cycle industrial equipment with removal and subsequent grinding of rubber.
Processing using universal crushers, which can be done at home yourself.

The first two methods require large investments. Third option accessible to everyone who has the opportunity and desire to make a crusher at home.

The necessary units can be make it yourself in a workshop or production site– where there are metal-cutting machines (lathes, milling) and a welding machine for the manufacture of component parts.

If you cannot perform mechanical processing of the workpieces yourself and you have to order them according to your own drawings, the cost of tire processing machines will still be several times cheaper than similar purchased units.

The main component on the tire conversion line is a shredder (rubber shredder). Let us consider in more detail the purpose of the components of this machine.

Unit design

The machine consists of the following main components:

electric motor 5 kW – 2 pcs;
housing with disk shafts;
lattice;
worm gearbox – 2 pcs.;
shredder frame;
loading hopper;
guide tray;
control cabinet.

The installation parts are mounted on a powerful frame welded from channels.

Box with cutting discs

The main unit of a rubber crusher is a housing with milling rolls.

Wherein cutting knives made of high-strength steel and heat-treated, which significantly reduces their wear. They practically do not require sharpening during operation.

The calculation of the box openings, shafts and cutting elements must be accurate, so it must be done by a specialist in this field (designer).

Grid for calibrating crumbs

In order to obtain a calibrated fraction of tire raw materials, shredders are equipped with a special grid, which is installed under the rolls.

Worm gearbox

The rotation of shafts with disk cutters is carried out separately, directly from worm gearboxes connected to electric motors through couplings.

The gear ratio is selected from 25 to 35 so so that cutting occurs without jamming and at sufficient speed.

Unit frame

The frame is welded from profile elements, ensuring the reliability and stability of the unit during operation, as well as loading and unloading operations.

Loading hopper

The tire recycling plant is equipped with a tire loading hopper and a tray for removing finished crumb rubber.

Thanks to its design, the bunker eliminates the formation of congestion from raw materials and guarantees directed movement of the mass towards the rotating rollers.

Tire cutting device

Installation for cutting tires and removing cords consists of a supporting frame and a stand.

The frame contains a tire clamping mechanism that rotates with the tire during cutting. Engine speed is reduced due to different pulley diameters. The stand has a built-in wedge cutter, which is adjusted to a specific size by moving the quill.

How to shred tires?

The technological chain is some preparatory stages , before the product of the required fraction is obtained.

This procedure includes:

Inspection and removing foreign objects from the tire cavity.
Cord cutting.
Tire cutting on strips measuring 50-80 mm.
Grinding raw materials through a shredder.
Separation and separating metal from textile parts.
Calibration crumbs into fractions using a vibrating sieve.

Equipment performance

The operation of these two main units when processing tires done semi-automatically.

For normal operation of this line, a room of about 150-200 sq. m is required. meters. This is due to the fact that you need a place to locate not only equipment, but also to store used tires, finished tire products and metal waste.

The production of crumb rubber on this equipment per hour will be approximately 200-800 kg and up to 100 kg of metal scrap; 2-3 unqualified workers will be needed to service the machines.

In addition to tires, this equipment can process other rubber (conveyor belt, inner tubes, gas masks). The output is crumbs with dimensions from 0.7 to 4 mm, while it makes up 65-85% of the total mass of raw materials.

Where to use the resulting raw materials?

All those who have decided to start a business of processing worn rubber into crumbs are faced with the dilemma of choosing the right equipment for their enterprise. But not all equipment offered on our market will bring you real and stable income!

Choosing the wrong equipment entails:

- losses and wasted time;

- loss of your investments once and for all!

You will have to invest above the price in additional components. If the equipment “stops”, then every day of downtime is money that has passed PAST you. Low-quality equipment will not be able to provide you with high-quality crumb rubber and the required volume to recoup production costs. The issue of equipment payback will drag on for many years or you will have to forget about it altogether, not to mention the profit!

Of course, European equipment for processing worn rubber is high-quality and reliable, but the cost of this equipment (on average about 2 million euros or more) is an unaffordable amount for many beginning entrepreneurs, especially since the payback for such equipment will be more than 7 years, which, of course, becomes uninteresting and illusory in the face of growing competition and constantly changing events. And it’s not a fact that the equipment will be manufactured in Europe. For example: many well-known companies in our, European or American markets pass off their equipment as European, although they assemble it entirely in China. There are a lot of examples of such companies - manufacturers (resellers). For example, one famous American company, which is also represented on our market, simply resells equipment from the Chinese manufacturer under its own brand. The same companies (resellers) are present on the Russian market, passing off their installations as their own and convincing that they were either assembled in Europe, or assembled by them, but with European components and so on. No matter how you twist these numerous phrases, the essence does not change. China is China, and if you decide to buy equipment from Chinese manufacturers, then buy it without numerous intermediaries who inflate more than 100 percent of the marginal profit on non-functioning equipment, without bearing any responsibility, much less a guarantee. And the breakdowns will be serious and permanent.

For greater clarity and understanding by you this issue We will analyze all the pitfalls that you may encounter when purchasing equipment.

The bulk of the equipment offered in our country includes a so-called preparatory group. Sellers explain its necessity by saying that by preparing the rubber before feeding it into the shredder, productivity increases, the knives in the shredder become less dull, and so on. All this is pure fairy tales and inventions of ignorant “professionals”! This only reduces productivity, and the knives in shredders, if they are made of the right steel, are dulled more quickly by the rubber itself than by rubber that contains a metal cord.

Returning to the preparatory group, let's consider its components:

1 . Puller for metal bead ring of tires. Used to pull out the bead ring. Costs: work requires one person, additional electricity; if the unit breaks down, you cannot work on the tire processing line (it risks breaking the shredder and impact crushers). If for some reason it was not possible to pull out the bead ring, it must be cut from the tire using a grinder or a special cutting machine. The average time to tear out or trim a tire bead is about 7-10 minutes on each side.

2. Machines for cutting prepared tires into strips and chips. Used for cutting small pieces of rubber (average up to 15 cm) for feeding into the main shredder for processing. Costs: one person is required to operate the machine, additional costs for electricity and maintenance, in case of breakdown, the entire equipment stops. The average time to cut one truck wheel into the required chips is 15 minutes.

3. Guillotine shears and other additional units for cutting prepared tires into pieces. Used for cutting truck and passenger tires for easy feeding into the shredder. Costs: One person is required to operate the machine, additional electricity consumption and other consumable parts. The average time to cut one truck wheel into the required chips takes 10 minutes.

So, what do these auxiliary machines and units give you? There is only one answer - expenses, breakdowns, high production costs of the finished product and numerous costs for repairs and modernization of equipment.

The real cost of producing crumb rubber using equipment with a preparatory group is 12-13 rubles (or even higher) per kilogram, provided that this equipment is working properly. And most importantly, it is simply not realistic to process the volume of tires according to the stated characteristics! Many enterprises that operate on similar equipment work in two shifts (during the day they prepare rubber for processing, and at night they process what they prepared during the day), but even then they cannot get two tons of finished crumbs from the same 500th model. thereby earning a maximum of 3,000 rubles per day. And then only when the equipment is working properly. It is much more profitable with such profitability to work in a taxi or even as a loader, and there is nothing funny about that!

It is IMPOSSIBLE to operate such equipment profitably. Don't reinvent the wheel, look at things with real eyes, otherwise you will get what many people got. (to enlarge, click on the photo).

Equipment for grinding worn rubber from our company

In turn, we offer you actually working equipment, where the real cost of producing a kilogram of crumbs does not exceed 5.5 rubles:

Equipment in which, from the entire preparatory group, only guillotine shears are included, which are used only for cutting truck tires into 4 uniform parts.

Equipment that actually employs 3 people.

Equipment that actually processes the volume stated according to its characteristics.

Equipment that is entirely made, developed and assembled in Russia.

Equipment on which you can actually make money with more than 100% marginal profit!

The price of the crumbs will depend mainly on the quality of the raw materials, and secondarily on the fraction.

The most popular is crumb, the fraction of which is 2-4 mm.

It's great for creating:

The popularity of such crumbs is due to the fact that a minimal amount of glue is used to glue these granules together. And a polyurethane binder is sometimes 5-8 times more expensive than crumbs.

Conclusion

Making your own tire crusher is a good idea for those who want to make their own crumb rubber, but are not ready to spend tens of thousands of dollars on equipment.

You can create a chopper if you have a carpentry workshop, as well as certain skills and materials, or use the services of people who specialize in this.

The crumbs obtained at home can be used for your own needs or sold to businesses and the public.

Making crumb rubber with your own hands at home

IN last years The use of crumb rubber and materials made on its basis for decorating plots, organizing paths, and covering the roofs of houses has become fashionable. Crumb rubber can also be used to create waterproofing for building foundations. In order to use elements made from crumb rubber on your site, you can contact a company that professionally works with crumb rubber. However, working with this material is not so difficult. If you wish and have free time, you can make crumb rubber at home with your own hands.

What is DIY crumb rubber made from?

When solving this issue, you can go in two ways. Path number one relies on the transition of rubber to a brittle state at low temperatures. If at home it is possible to cool the source material for preparing crumbs to a temperature of -70 ... -80 degrees Celsius, then it will be possible to obtain crumbs from any type of source materials. However, solving this problem at home is not so easy.

Path number two is to competently select the source material. As we know, crumbs can be obtained from tires and tubes from car wheels. But tires are very difficult to grind under normal conditions, and it is also difficult to extract the metal cord from them later. For this reason, to obtain crumb rubber at home, it is better to use old worn-out tubes as raw materials. This material can be cut quite easily using improvised tools available in any home.

How to make crumb rubber at home?

On initial stage it is necessary to prepare a sufficient amount of raw materials, i.e. old car inner tubes and corresponding cutting tools. To produce a coating with an area of one square meter and 10 mm thick you need about 8 kg of crumb rubber. When producing crumbs from old chambers, the loss of material by weight is minimal. Thus, it is necessary to prepare the starting material at the rate of 8 kg of old cameras per 1 square meter of coating.

To grind rubber, you can use ordinary scissors or an ax. If desired, you can build special guillotine shears. As a last resort, you can organize the cutting of cameras sufficiently sharp knife.

Making crumbs should be done according to the following algorithm:

Remove all metal elements from the old camera
Cut the camera into thin strips
Grind the thin strips obtained in step 2

Tire recycling at home

Every motorist knows that recycling used tires is a serious problem. However, recycling tires at home has several options. Let's look at some of them.

Creativity

There are many examples of creating original sculptures from waste tires, used to decorate the garden, or as an independent work of art. Garden variations can be embodied in the form of swans, garden vases, etc.

The “pattern” is extremely simple and understandable. And the created images are very similar to living prototypes.

There is also a more artistic approach to rubber waste. From them, like from clay, the intended sculpture is literally “molded”. You can, for example, sculpt a horse, and one so hot that it will arouse the approval of other venerable sculptors.

Pragmatic approach

Still, for most, recycling tires at home means using waste rubber for the benefit of home and his farm. There are several nuances here.

First, you can use used tires for your home as they are.

Secondly, you can use in the household the product of their primary processing, obtained in small and large enterprises.

Thirdly, it is possible to organize, within the framework of a private, home-based company, production that deals with primary processing tires

Using tires as a permanent material

Tires, as you know, are one of the best building materials. Some craftsmen used tires from Belaz as a support, a foundation under a garden house. And zealous owners can use tires as elements:

fence
mini flower beds
elements of playgrounds

Use of partially recycled rubber

Tire recycling is carried out in stages:

cutting and crushing
plasticization and output to the final product

Semi-finished product used for different types production, serves as crumb rubber. You can make fuel from it, or you can make tiles, both for asphalt and for roofing. It is also used for the production of shoes, sports field coverings, etc.

In the household, you can even use crumbs in the form of a semi-finished product - they sprinkle it on the paths along the lawns. You can also use rubber roofing for your home.

Recycling of unusable tires

Tires are crushed - either in a cooled state to -70...-80 degrees, when the rubber becomes brittle, or at normal temperature - but with a more powerful tool. To obtain fuel, rubber is subjected to pyrolysis.

This is an environmentally hazardous process. Equipment, maintenance of space, organizing the collection of raw materials and searching for buyers, attracting significant funds - all this is completely associated with a small “private shop” where recycling tires would be profitable.

Conclusion

As part of a car enthusiast's household, recycling tires is quite difficult. To do this you need to be a very big enthusiast. But maybe you'll be lucky enough to find a unique way to use up your junk tires.

technology for processing car tires, tires and other rubber, description and video of the manufacturing process

Life time car tires quite short, after which they must be replaced.

Disposal of used tires is a big problem for the environment around the world.

Every year the number of cars in use increases by almost 10%.

Obviously, tires need to be recycled.

In this article we will cover the following questions:

what is the technology for processing tire crumbs;
what equipment is used;
where crumb rubber is used;
Is it possible to make it yourself?

Tire recycling methods

The raw material for producing crumb rubber can be not only worn tires, but also any other used rubber products.

In practice, only two main methods are used to obtain crumb rubber from waste tires:

shock wave;
mechanical.

Let's consider both methods separately.

Shock wave

This technology for grinding car tires and other rubber waste into crumbs was invented relatively recently.

The processing process consists of cooling the products to ultra-low temperatures, followed by crushing by a shock wave.

Cryogenic chambers are used for freezing, and the shock wave is generated by a special electrical device or by detonating a small amount of explosive.

This technology for processing used car tires requires the installation of expensive equipment, which is economically beneficial only for large enterprises with large volumes of raw materials.

Mechanical

This is a classic technology for processing tires into crumb rubber, which, unlike the first, is used everywhere.

The essence of the process is a step-by-step mechanical effect on raw materials to obtain the required fraction of crumb rubber and by-products.

There are several methods for recycling tires by mechanical action:

grinding at normal temperature;
at high temperature;
with cooling of raw materials;
using an “ozone knife”;
pressing raw materials with a powerful press through special dies.

The most popular method is conventional mechanical grinding at normal temperature.

This technology is classic and is perfect for organizing small enterprises for recycling waste tires.

Classic tire shredding technology

If you have the necessary equipment, this technology allows you to obtain crumb rubber of any fraction, down to a dusty substance.

The entire tire recycling process can be divided into several stages, each of which uses a specific type of machines and mechanisms.

The main technological stages of tire crushing and the types of equipment that are used at each of them:

At the first stage of processing, tires are sorted by size, which is necessary to configure the equipment for certain tire dimensions. The crushing itself begins with cutting out the bead rings on a special cutting machine.
The second stage of tire shredding occurs using hydraulic shears, mechanical cutters or guillotines, which are used to cut into strips and medium-sized pieces.
The crushing process continues in a special shredder, where large pieces of rubber are crushed into small chips ranging in size from 2 to 10 square meters. cm, which are supplied to the next technological operation.
At this stage, the final grinding of the raw materials to the required fractions occurs. Rotary mills with tetrahedral knives or other equipment capable of withstanding enormous mechanical loads are used.
After complete shredding of waste tires, it is necessary to separate the resulting rubber crumbs from by-products: chopped metal court and textile waste. For this purpose, magnetic and air separators are used.
At the final stage, the resulting rubber crumb is passed through a special vibrating sieve, where separation into fractions occurs. The resulting material is packaged and sent for further processing.

This is the classic diagram of the technological process of crushing tires into crumbs at normal temperatures with an approximate list of machines and mechanisms.

The number of processing steps can be reduced or increased depending on what equipment will be used and what kind of crumbs need to be obtained at the output.

Transportation of raw materials from one technological operation to another can be carried out either manually or automatically.

If the movement of tires, pieces of rubber, chips and rubber crumbs is carried out using belt and auger conveyors, then the entire complex of equipment for recycling old tires, in fact, becomes a production line.

For organizing a small recycling workshop, installing an automatic line is the optimal solution.

What equipment is needed?

There are a lot of offers on the tire recycling equipment market.

Russian and foreign manufacturers offer both fully equipped lines and plants, as well as individual machines, devices and mechanisms. The price will depend on the type and performance of the unit.

Let's consider the minimum set of what is needed to process tires into crumbs.

Bead removal machine

This is the first unit in the entire technological chain of shredding tires. Its purpose is to remove the seat rings from the tire.

The operating principle of bead removal machines is based on:

cutting down;
cutting;
tearing out the seat rings.

Each method does not have any advantages over the others.

Further processing of the removed rings is carried out on squeezing machines, where the metal base is squeezed out and the remaining rubber is crushed in the general flow.

Tire shredders without beads

shredders;
tape cutters;
hydraulic shears;
roller grinding devices;
mills.

The production line may include several such devices:

Hydraulic shears and tape cutters cut tires into large pieces.
Shredders process them into smaller fragments.
Roller units and mills bring the raw material to the required fraction.

Separators for metal and textile removal

A magnetic separator removes chopped metal court residues from the rubber crumb.

The principle of operation of this device is simple: a powerful electromagnet pulls metal waste from the mass of raw materials and sends it to the receiving hopper.

Removal of textile residues occurs in a cyclone-type air separator, where a powerful air stream simply blows light textile fluff into the receiving hopper.

Read more about textile and metal cord, as well as where it can be used profitably, here.

Vibrating sieves for separating the product into fractions

Complexes for processing car tires include at least two vibrating sieves: coarse and fine.

On the first device, large, not fully processed pieces of rubber are screened out, and on the second device, the standard fraction of crumb rubber is separated.

A vibrating sieve is a device consisting of a table with holes corresponding to the separated crumb fraction, and a mechanism that ensures the table vibrates at a certain frequency.

Conveyors and other mechanisms and devices

Tire recycling lines and plants include conveyor belts to move tires, pieces of rubber and crumb rubber from one process step to another.

Some manufacturers use screw conveyors in their lines to move and package finished crumb rubber. In addition, automatic tire processing lines are equipped with bunkers, security and process control systems.

All of the above equipment is included in automatic lines for processing old tires into crumb rubber.

The number of machines and mechanisms depends on the volume of production and the final type of product that needs to be obtained as a result of processing.

What can be made from the resulting granulate?

The crumb rubber itself, obtained by processing old car tires, is an intermediate product. Raw materials, depending on their fraction, are used in the production of the following products:

flooring for indoor and outdoor use;
curbs, bumpers and speed bumps for road construction;
substrates and gaskets to protect goods during transportation;
figures for playgrounds;
building materials - waterproofing and noise-absorbing;
dielectric products for the electrical industry;
MBR - bitumen-rubber mastic.

Granules are also added to asphalt mixtures, resulting in a strong and durable road surface.

From finely dispersed crumbs it is possible to produce various rubber products using the hot pressing method, namely:

bushings;
rollers;
rubber shoes;
many other products.

In addition, it can serve as an additive in the manufacture of new tires, thereby reducing its cost.

The entrepreneur receives not only crumb rubber, but also by-products of grinding: metal sheets and textiles, which are also liquid goods. They can be sold and get additional profit.

As you can see, for the tire processing business there are wide opportunities in terms of sales of products, because the need for it is very great in many industries.

Making crumbs from tires at home

Tire granulate can be easily purchased in online stores, construction supermarkets, or ordered directly from the manufacturer.

But for those who want to open their own small home business or simply make a covering for paths in the garden with their own hands, the issue of self-production becomes relevant.

In this case, it makes no sense to purchase expensive equipment for processing tires.

There will be no problems with raw materials for making crumb rubber at home. All you have to do is walk around your neighbors, who will happily take used tires out of the garage and get rid of them.

The simplest set of equipment and tools for shredding tires and other rubber products can be made with your own hands with minimal investment.

As mentioned above, rubber can be crushed mechanically or by freezing to a low temperature.

The latter option is unacceptable for home, since it will be necessary to purchase an expensive low-temperature chamber to cool the raw materials.

For the home, the optimal solution would be mechanical cutting and grinding of rubber to crumbs. In a separate article we described how to make equipment for these purposes.

Video on the topic

One of the manufacturers made an interesting and educational video about processing tires into crumbs, we invite you to see the process with your own eyes:

Conclusion

Crumb rubber is a multifunctional material, necessary for a person in many fields of activity. Its huge advantage is that it can be made from old tires, thereby giving a second life to outdated products.

Recycling rubber is not difficult; equipment for this purpose is available everywhere.

How do you think you can make money on certain types of household waste, not counting, of course, the services for its disposal? For example, on old, unnecessary car tires? It should be noted that there really are a lot of options.

Same as from plastic bottles, tires can be used to make decorations for the garden (flower beds, animal figurines, swings, sculptures, and much more). In general, collecting (or buying) and processing car tires is, as it turns out, a very profitable business, especially if you approach it with some imagination and using various modern technologies.

Based on the fact that such a large volume of raw material remains unclaimed, we can say that competition in this type of business is relatively small, even negligible. And finally, the most important thing is that the products obtained from the processing of car tires are extremely in demand now, and will be in demand for at least another hundred years. So, if you wish, you can pass on your established business to your grandchildren.

People have long begun to think about recycling used tires from cars, which increase by a huge amount every year. But no solution has been found. Of the total number of used tires, only a fifth is recycled. There are only recycling points for these old tires. By helping to improve the environment, you can earn extra money.

Worn-out car tires are quite valuable polymer materials. A ton of worn rubber contains approximately seven hundred kilograms of rubber, which can be reused, for example, as fuel, various rubber technical products and building materials.

At the same time, if such a ton of tires is burned, then two hundred and seventy kilograms of soot and four hundred and fifty kilograms of toxic emissions will disturb the environment. Recycle tires from economic benefit on the scale of a large industry it is unprofitable and very difficult. But, if you believe the manufacturers of mobile equipment for recycling, such production at a mini-enterprise can be a tremendous success and good profit.

Such a small plant consists of prefabricated equipment, which occupies an area of about eighteen square meters and is ten meters high. This equipment is capable of processing about five tons of consumables per day.

Moreover, the production area includes warehouses for worn-out materials (plastics and tires), an area for the preparation of raw materials (cutting tires into pieces), as well as a warehouse for finished materials such as liquid fuel, carbon black, and scrap metal storage.

What can you get from old rubber?

What is most surprising is that the recycling process car tires itself is finite, leaving behind virtually no waste. Let's see what can be obtained by recycling old tires:

Crumb rubber, which is used in the production of various gaskets and seals (including for plumbing purposes), shoe soles, rubber mats, rubber roofing (you can find out about liquid rubber for roofing here), Novotek seamless coatings, as an additive to asphalt , filling for punching bags, and for many other purposes.

Equipment for processing tires and rubber at the plant: installation

The need to recycle used tires arose due to the rapid increase in the number of cars in most developed countries. The number of used tires is growing every year, so the problem of their disposal has become acute for state authorities. Tire recycling equipment is not cheap.

Special plants and enterprises for their processing are being built. They solve environmental and economic problem related to the disposal of used car tires. This business, dealing with used tires, is already developing by leaps and bounds. First of all, this is facilitated by a large amount of inexpensive raw materials.

A tire recycling plant is built near the place where the product obtained after processing is sold, namely: crumb rubber, saw, steel cord, heating oil. A tire recycling plant is a cost-effective solution to the problem. It is located at a place where raw materials accumulate or near a factory that produces waste materials. The main thing is that the tire recycling plant is located at a distance of more than 300 meters from residential buildings.

Special equipment for the production of crumb rubber is installed at the plant. To open a business in this area, investments are required, however, due to the small number of competitors and the demand for this raw material, all investments pay off in the near future.

Waste tire recycling equipment

Equipment for rubber processing is a reactor installation. It is installed in a specially designated open area.

The average tire shredding equipment has the following productivity:

2 tons of liquid fuel
1.5 tons of solid residue containing carbon
0.5 tons of steel cord
1 ton of gas

The volume of tires that must be shredded is 5 tons per day. Processed products serve as raw materials for many types of production. The reactor itself operates using gas, which it itself is capable of producing when processing waste tires. The installation is low maintenance and requires only two people per shift. To work on such an installation, company employees need to undergo special training and study the features of the process.

Tire processing products include:

Rubber granulate and crumbs. Rubber crumbs come in different fractions: 0.1 - 0.45 mm.
Regenerate. Finely ground crumbs with improved quality. Dimensions: 0.6 - 10 mm.
Chips. Size 2 - 5 cm. Presented as pieces of tires along with metal cord.
Rubber plastic. Used in the manufacture of soft roofs.
Rubber floor Represented by polymer floor covering.
Bireplast. It is presented as a multi-layer waterproofing roll roofing material.
Reizol. It is represented by rubber plastic with an applied adhesive waterproof layer of rubber.
Fiber-reinforced concrete. A mixture of crumb rubber and two types of cord: textile and metal.

Rubber processing technologies

Rubber processing can be carried out in several ways. The choice of method ultimately determines appearance and demand for the resulting product. Within the scope of this paragraph, such a method as disposal in landfills will not be considered. Despite the fact that this option is the simplest, at the same time, the crumb production plant causes the least harm to the environment.

There are four main processing methods:

Crumb production - equipment for recycling tires into crumbs is considered the most rational, can process several tons of tires per year and brings a stable income to the owner. But the technology is not ideal; it has a significant number of disadvantages, such as the need to select raw materials with the same composition to standardize the properties of the final product.
Pyrolysis is the decomposition of tires under high temperature. This method is extremely inconvenient because during this process a huge amount of toxins are released into the atmosphere. Another obvious disadvantage of this disposal method is its economic disadvantage. Decomposition equipment is expensive and takes a long time to pay for itself.
Burning is the complete destruction of tires. The only benefit from such an action is the generation of energy, but such products do not perform very well as fuel. This is due to the fact that during combustion a large amount of soot is formed, which over time renders the equipment (furnaces) unusable. Since rubber contains sulfur, when using this disposal method, the substance enters the atmosphere and when interacting with water, sulfuric acid is formed.
Restoration is a process similar to recycling. This is the most promising and rational way. Thus, when making one new tire, approximately 30 liters of crude oil are consumed, and only 5 are needed to refurbish it.

In recent years, business in this area has been gaining momentum; it is especially popular in European countries, since this is where society takes environmental protection most seriously.

Another clear advantage that this business is famous for is the purchase of inexpensive equipment for processing tires into crumbs. You can set up a recycling plant with your own hands in any room, even in your own garage.

Line for processing tires into crumbs

The tire recycling line produces crumb rubber for business; it is considered environmentally friendly due to the absence of emissions into the atmosphere or into the ground.

The line and all equipment must be made in accordance with the requirements of the Russian Federation, which were put forward for equipment of this type:

According to the level of noise emitted.
By the amount of harmful emissions.
According to life safety.
According to the safety of waste processing.

The entire line for processing tires into crumbs consists of sectors:

Preparatory, which includes 2 machines: 1 – for removing bead wire, 2 – scissors for cutting tires.
A crusher consisting of 1 – crushing chamber and 2 – return sifter.
Crushing rollers, which are two drums that rotate at different speeds towards each other.
A granulator that delivers the mixture from the hopper to the crushing zone.
Vibrating table of a magnetic selector for uniform distribution of the mixture under the influence of vibration.
Knife granulator, consisting of a body with knives, a shaft with knives, a mesh whose hole diameter is 4 mm.
Vibrating table in the form of an inclined rectangular structure.
Magnet for collecting small wire residues.
Textile separators for a high level of crumb cleaning from existing textiles.
Automatic packers filling bags with crumbs.

This is what the process of processing tires into crumbs looks like, serving as recyclable materials for further production. Organizing this recycling business is not difficult. This is due to the relative cheapness of the equipment and fast payback periods. The main mission of this business is to protect the environment.

Recycling old tires at home

Processing tires into crumbs at home and at the factory

It should be noted that this rubber waste is a flammable material, and if a huge number of tires catch fire, they can pose a threat of poisoning to everyone nearby, since rubber releases carcinogenic toxins when burned, such as benzopyrene. Storage in landfills leads to the proliferation of rodents and insects, which are sources of dangerous infections. To avoid deterioration of the environmental situation in Russia and abroad, proper disposal, namely waste recycling, is required.

Without constant recycling, an environmental crisis could occur very soon.

Recycling

Powder from waste of larger fractions is used in the production of composite roofing materials, rubber-bitumen mastic, waterproofing materials, and rubber coatings. Scrap metal is obtained from metal cord, which is also used by Russian entrepreneurs.

Also, textiles and rubber are obtained from tires.

Recycling at home

According to one scenario, the rubber should be cooled to a temperature of approximately -75 °C. Agree, not everyone has such an opportunity. So let's use the traditional scenario:

Take your cameras
Remove all unnecessary elements from them
Cut them into thin strips
Chop these strips

The rubber grinder in this case is an ax or scissors.

Mechanical processing method

The most professional method.

A production line is a sequence of installed working devices, through which the material becomes a finished product.

Processing into crumb rubber goes through three stages:

Today there are a sufficient number of manufacturers of this equipment on the Russian market.

Chemical processing method

There is also an effective, but expensive physical chemical method processing tires into crumb rubber - cryogenic grinding of car tires. Crushing of rubber is carried out in a special cooling chamber at extremely low temperatures (down to - 120 ° C). A refrigerant (liquid nitrogen) is supplied to this chamber, cooling it to ultra-low temperatures.

Under strong cooling conditions, rubber acquires a glassy state. Crushing of rubber occurs when struck with a special hammer.

After grinding, textiles and metal are removed from the rubber crumb.

The processing of car tires to obtain crumb rubber is carried out in several stages: Note that the processing of rubber can be either crumb or diesel fuel. But the latter option requires serious material investments. This process consists of sorting and subsequent grinding of tires, and then the selected and prepared material is loaded into a special reactor, which extracts fuel from recycled materials at high temperatures.

Disposal and recycling of car tires

Let's see what can be obtained by recycling old tires: crumb rubber, which is used in the production of various gaskets and seals (including for plumbing purposes), shoe soles, rubber mats, rubber roofing (you can find out about liquid rubber for roofing here) , Novotek seamless coatings, as an asphalt additive, as a filler for punching bags, and for many other purposes.

Business idea: tire recycling

Its waste is released into environment.

This cannot be called a good solution, but the emissions resemble exhaust gases from a truck.

As for the remaining mass, it passes through a magnetic separator, so to speak in simple words, then sifted through a sieve. Metal elements are screened out and sent to the warehouse.

Fuel oil is transported by conveyor to tanks, in which the fuel will be stored until dispatch.

Tire recycling: step-by-step opening of production

Therefore, the choice is obvious: it is better to recycle used tires and get paid for it than to simply burn them, causing harm to the environment.

Based on the chosen method of processing tires, you can obtain different products: Let us consider the process of tire processing using the example of the production of crumb rubber, which has wide range applications. So, the process consists of the following stages: Subsequently, the resulting crumbs can be converted into fuel / gas / fuel oil.

In recent years, the use of crumb rubber and materials made on its basis for decorating areas, organizing paths, and covering the roofs of houses has become fashionable. Crumb rubber can also be used to create waterproofing for building foundations. In order to use elements made from crumb rubber on your site, you can contact a company that professionally works with crumb rubber. However, working with this material is not so difficult. If you wish and have free time, you can make crumb rubber at home with your own hands.

What is DIY crumb rubber made from?

How to make crumb rubber at home?

At the initial stage, it is necessary to prepare a sufficient amount of raw materials, i.e. old car inner tubes and corresponding cutting tools. To make a coating with an area of one square meter and a thickness of 10 mm, about 8 kg of crumb rubber is needed. When producing crumbs from old chambers, the loss of material by weight is minimal. Thus, it is necessary to prepare the starting material at the rate of 8 kg of old cameras per 1 square meter of coating.

To grind rubber, you can use ordinary scissors or an ax. If desired, you can build special guillotine shears. As a last resort, you can organize cutting of the cameras with a fairly sharp knife.

Making crumbs should be done according to the following algorithm:

Remove all metal elements from the old camera
Cut the camera into thin strips
Grind the thin strips obtained in step 2

Each of us knows that a vehicle cannot do without tires. However, not everyone thinks about where worn-out tires go. There are two ways: either the tire is sent to a landfill and thereby pollutes the environment, or it is recycled. It is safe to say that rubber is a dangerous pollutant, which is why they always try to recycle it. For this simple reason, there are all the prerequisites for creating your own small plant, where tire processing will be carried out.

What everyone should know

Every year the number of cars on the roads increases by about 5-10%. Based on this, the volume of worn rubber increases by approximately 1 million tons. In many countries, the issue of recycling is very acute. This problem can be partly solved by setting up your own small production. You have several options for business development. For example, this could be the processing of car tires into fuel oil or crumbs. If you want to receive fuel, you will have to spend a little more money, since the production line is quite serious. Please also note that you can work not only with tires, but also with plastic products, which will slightly increase the profitability of the enterprise. This business has several undeniable advantages, now we will look at each of them.

Firstly, you do not need to invest a lot of money in purchasing raw materials. This is due to the fact that worn tires are thrown away. Local authorities, if, of course, they are concerned about the ecology of their city, will deliver everything to you themselves. But that’s not all, since the municipality is ready to pay for your company to process car tires. Agree, getting practically free raw materials, and even making a profit from doing this business, is not at all bad. Of course, it doesn’t end there, since our main goal is not only to save the environment, but also to make a net profit. Fixed funds will come from the sale of the same fuel oil, which is an extremely popular type of fuel in agriculture. By the way, you can also get free raw materials at tire service points, which are located in big cities more than enough. The thing is that service station employees, etc., pay additional money for the removal of old tires and their disposal.

Recycling rubber tires: pros and cons

It is impossible not to say a few words about the fact that this niche has not yet been fully filled. The number of entrepreneurs in this area is relatively small, approximately 20% of the optimal figure. This means that only a fifth of worn-out rubber is disposed of and recycled, the rest is sent to a landfill. You must understand that 1,000 kilograms of burned tires means 450 kg of various toxic gases, as well as 250-270 kilograms of soot. But if the same amount of rubber is properly disposed of, then about 700 kilograms of full rubber can be obtained from the waste, which can be used to make fuel and rubber products. Here it hardly makes sense to talk about the industrial scale of the enterprise, but it is very possible to set up a small tire processing plant.

The complex itself is relatively small, but its size directly depends on production volumes. So, to process 5 tons per day, you need a room of 18 square meters and 10 meters in height. There should be a warehouse on the site where you will store tires, plastic, etc. There must be an area for preliminary preparation of raw materials (cleaning, cutting rubber). You can’t do without a storage room for finished products. In this case, it all depends on what exactly you are getting. It could be fuel and so on. For example, for fuel oil you will need to purchase several large-capacity tanks. They don’t have to be new; it’s even better to buy used ones, it’s much cheaper. Please note that recycling rubber tires is difficult and dangerous. Therefore, technology must be carefully followed. Let's talk more about this.

Technological process

In essence, there is nothing complicated here, but it is necessary to control the process at all stages of production. At the very beginning you have to start collecting tires. Next, you must take them to your company’s warehouse for further processing. In order not to damage the scissors, which, by the way, are not cheap, it is necessary to inspect all raw materials for the presence metal objects, such as discs or rings. Concerning cutting tool, then ideally these should be hydraulic shears, but this is not at all necessary, we will talk about this a little later. Next, the crushed rubber is sent to the reactor - a special installation for processing tires, which operates at a given temperature, most often 450 degrees Celsius. Decomposition leads to the fact that we obtain several semi-finished products, for example gas, steel cord, and fuel fraction.

The same gas is used to support combustion in the furnace as a by-product fuel. Its waste is released into the environment. This cannot be called a good solution, but the emissions resemble exhaust gases from a truck. As for the remaining mass, it passes through a magnetic separator; in simple words, it is sifted through a sieve. Metal elements are screened out and sent to the warehouse. Fuel oil is transported by conveyor to tanks, in which the fuel will be stored until dispatch. It should be noted that the tire processing plant, which produces pyrolysis fuel, is quite expensive - approximately 2 million rubles. Its productivity is about 5 thousand tons of raw materials per day, which is quite a lot.

Making crumb rubber

Here's another one is enough interesting idea, which has not received proper distribution to date. The essence of such a business is that you will sell crushed and processed rubber, which can be used for various purposes. In order for you to roughly understand what we are talking about, it is necessary to provide general indicators in numbers. So, a ton of crumb rubber on Russian market will cost no more than 20,000 rubles. As for the main consumers, these are construction companies, manufacturers of rubber products, roofing materials, coatings for construction and sports tools, etc. In principle, it is quite easy to find a sales point.

It is also necessary to take into account the fact that approximately 700-800 thousand tons of worn tires are thrown away every year on the territory of the Russian Federation. Approximately 20-25% is disposed of properly, the rest either just lies in landfills or is burned. So, processing tires into crumbs can bring in 5-8 billion, but this is already on an industrial scale. If you will be engaged in this kind of recycling at your plant, then you will need a mechanical crusher. will have to be changed very often, which leads to high costs. Another disadvantage of this idea is that a lot of electricity is consumed, approximately 500 kilowatts per ton of finished product. Nevertheless, recycling tires in this way will be profitable. But only if you receive appropriate support from the state.

Tire recycling equipment

Separately, we need to talk about what our production line will consist of. In principle, there is not much equipment, and it is not complicated at all. However, the price is steep. The main unit is a tire processing unit (reactor), 10 meters high, 3.5 meters wide, 5 m long. This unit must be installed only in an open area, that is, in the open air. You, as a future entrepreneur, must understand that you will have to pay quite a lot of money for electricity. The reactor itself consumes about 6 kW per hour. In addition, there are also scissors - 7-8 kW/h. In principle, this is practically all the equipment that is needed to start production. What else is needed is several crucibles for unloading the resulting material.

As noted above, the reactor has a capacity of about 5 tons per day. But of this mass, approximately 40% will be liquid fuel. The fact is that as a result of decomposition you will get gas (about a ton) and about 0.5 tons of steel cord. We must not forget about the solid residue (carbon-containing materials), this is approximately 30% of the total output. It is worth drawing your attention to the fact that the processing of old tires in the reactor is carried out in a continuous mode. All you have to do is add tires. Combustion is supported by gas produced inside the firebox. The reactor must be maintained by two specially trained specialists. In principle, training courses can be completed fairly quickly. Now let's go ahead and look at a few more important points.

How much money do you need to start?

This is one of the main aspects that interests absolutely all beginners. There is no need to spend a lot of money here. If you are going to purchase used equipment (reactor, scissors), you can save up to 20% of the total amount. Whether to take such a step or not is up to you to decide. There is no guarantee that a used reactor will not fail after the first melting. In this case, no one will compensate you for the damage. One million rubles should be enough for you to do everything. This includes the cost of a reactor with a capacity of 5 tons/day, as well as scissors. In addition, you will need to purchase several tanks (60 tons). If these are used containers, then you will have to pay about 25,000 rubles per unit. Decide for yourself how many pieces you need, but you don’t need to limit yourself to one or two tanks. The fact is that processing tires into fuel is a seasonal business.

During a period of decline in fuel prices, it is better not to sell it, but only to accumulate it. When the period of increase comes, and this will definitely happen, you can get a good income by selling all the fuel oil at once. This tactic works and is considered quite effective. But this does not mean that you should completely freeze sales; it is enough to reduce them by 50-75%. You still need to pay your employees. Four specialists will cost approximately 60,000 rubles per month, and tools and workwear will cost another 50 thousand. There are also regular monthly costs: electricity, taxes, rent, etc.

About enterprise income

As you may have noticed, the technology for recycling tires is quite simple. There are no complex fuel additives here. chemical reactions and other points. Moreover, as noted above, the raw materials are completely free. Sometimes you can even earn some money by collecting tires, which will cover your monthly electricity costs. If you live in the outback, then you are unlikely to be paid for recycling, but in big cities the situation is completely different. There are many industrial enterprises that pay good money for recycling rubber. This is due to the fact that many city landfills refuse to accept such waste. For recycling a ton of tires you can get a different amount, from 2 to 5 thousand rubles.

It is safe to say that even recycling tires at home will bring good income. So, per ton of carbon Low quality consumers are willing to pay 3 thousand rubles. Scrap metal is accepted at the rate of 4 thousand rubles per ton, and fuel oil - 3-4 thousand rubles per ton, depending on the period. By simple calculations, you can come to the conclusion that in a month you will earn approximately 350,000-400,000 rubles. Approximately 50% must be paid for electricity, paid to workers, etc. With such intensity, the tire recycling line will pay for itself within six months, which is quite fast. As you can see, the idea is very interesting and promising, but not everything is so simple. In such a business, as, in fact, in any other, there are a lot of pitfalls. Let's see how not to make mistakes.

Problems when starting a business

It happens that you simply cannot find a free plot of land. This is due to the fact that it is necessary to maintain a safe distance to residential buildings, which is 300 meters. The further the plant is from the city, the higher the cost of delivering raw materials, do not forget about this. Remember also that not everyone wants tires to be recycled outside their windows. Feedback from ordinary residents will be negative, even if the reactor is located 400 meters from residential areas. For this simple reason, look for a location on a production site. Chances are you'll find one, as quite a few of the sites are empty. All you need to do is negotiate directly with the company; as a rule, this is not so difficult to do. At least, it’s much easier than concluding an agreement with firefighters and the sanitary and epidemiological station.

Do not forget that you need a license. It is not difficult to obtain a permit, since tires are classified as non-hazardous materials (group 4). But the catch is that your production officially pollutes the atmosphere. Most likely, you will be asked (forcibly) to buy a treatment plant. Its price is usually several times higher than the entire plant. But there are several ways that will help you postpone the purchase for a certain time. Experts say that it is not advisable to open a plant for processing any one material. Whether this is true or not, decide for yourself. In any case, you can always expand your workshop and melt glass, plastic or metal there. According to statistics, 75% of entrepreneurs encounter environmentalists who are wary of this type of production.

A few important details

As noted a little above, you will encounter a “contingency” item in your business plan. This is due to the fact that it will be necessary to resolve issues with environmentalists and firefighters. For example, to store fuel oil in new tanks, only a protective shield is needed, but used tanks require additional protection. There are special lines for fuel and gas, fire safety instructions for personnel, and much more. In any case, you need to have a reserve in your budget of several hundred thousand rubles. This will save you a lot of trouble. The expense items are quite large, but we have already covered them, and you probably know what you will be dealing with.

Do not forget that you, as a manager, must not only observe how your employees work, but also perform a number of other tasks, no less important tasks. Among these: constant development and growth of the boundaries of the enterprise, accounting and tax accounting, as well as adjustment of goals and plans for the near future. This article did not mention one important point - advertising your product. There are several options here. One of them is to create your own thematic website where you can offer fuel oil, etc. No one has canceled the advertisements on poles, stops and stands. Until now, this is a good and effective method to loudly declare oneself. In addition, for a nominal fee you can rent a billboard and place your advertisement there. By the way, you need to do this wisely. It is important not to overload with unnecessary information, but also to attract the attention of a potential audience.

Conclusion

So we talked to you about what tire recycling is and how to open such a business. As you can see, everything is quite simple, but there are a lot of important points. Sometimes it happens that it is difficult to find a supplier, or the latter refuses to just give away old tires and demands money for them. In principle, you can find another, more acceptable enterprise, where they will be happy to get rid of excess garbage, and they will even give you money for the trip. Sometimes it makes sense to enter into a full-fledged long-term supply agreement. This way you can eliminate downtime in your business and increase your income. But all these points must be discussed directly with the supplier. Remember that it is much more difficult to find a point of sale for tires than to find a businessman who is ready to buy this garbage. This is due to the fact that in some cities there are no tire recycling reactors at all.

If you get good fuel oil, then aim for city or private boiler houses. There you will be happy to purchase fuel, which is vital for heating water. If you are going to get crumb rubber, then you will need a machine that costs about 500,000 rubles. Electricity consumption per 1 ton of product is 90 kW. The disadvantage of this approach is that a group of knives (40 pieces) wears out after processing hundreds of tires, so they often need to be replaced. In principle, you only need to pay 30 rubles for one knife, which is relatively little. Thus, a unit with a productivity of 20 tires per hour pays for itself in about six months. The results are the same as in the production of fuel oil. But in the first case, there are fewer problems with environmentalists and firefighters, since we are not dealing with either waste into the atmosphere or liquid fuel. Well, that’s basically all on this topic. The most difficult thing is to start, and then it will be much easier.
