Business idea: tire recycling. Production of crumb rubber from tires: technologies and methods

With the increase in the number of road transport as a result of an increase in the volume of waste, the issue of the environmental situation has become acute. Every year, thousands of tires are taken to landfills and landfills, where they become a source of negative impact on the environment.

Car tires belong to class 4 hazardous waste due to the carcinogenic and toxic substances released during the decomposition process, which destroy the biosphere envelope. IN last years, waste disposal requirements in large cities have become more stringent, and compliance with rubber product recycling techniques is regularly checked.

Rules fire safety It is prohibited to store tires due to the possibility of spontaneous combustion. An active person with basic knowledge of physics and carpentry skills can turn rubber waste recycling into the main source of income. Rubber crumbs obtained during the recycling process appear secondary raw materials in the manufacture of goods.

What is crumb rubber made from at home?

Crumb rubber is produced from deteriorated car tires, they are better amenable to mechanical action and removal of metal wire (cord). Recycling waste tires allows you to obtain crumbs of the required diameter with minimal losses of raw material. Three-dimensional figures cut from tires are used as decoration in the courtyards of residential areas or garden plots. You can often find flower beds, low fences, and playground fencing made from tires.

Large-sized rubber crumbs are used to lay out the paths of private houses and summer cottages, giving them an aesthetically pleasing appearance. beautiful view. Play areas and sports grounds are equipped with rubber coatings with waterproofing and noise-absorbing properties.

Recycling small amounts of rubber at home

Receiving small volume crumb rubber for personal purposes does not require a large amount of raw material and special equipment. You can use available tools such as scissors, a guillotine cutter or an ax. A well-sharpened knife will also work for cutting old tires.

Stages of processing tires into crumbs at home:

cord removal
cutting waste tires into strips
grinding of the resulting raw material

Dealing with large volumes of rubber waste for commercial and personal purposes requires financial investment, the purchase of equipment and a facility to process the raw material. The cost of units offered by manufacturers depends on their power and configuration. Domestic and imported manufacturers provide full-cycle rubber waste recycling lines. Having basic knowledge of physics, you can make equipment for processing tires into crumbs with your own hands, meeting your personal needs.

Methods for making tire crumbs

Methods for obtaining crumb rubber:

Cooling of raw materials with liquid nitrogen to a brittle state and subsequent grinding. This type of processing requires special freezers, cooling of the raw material is carried out to a temperature of -70 - -90 degrees and is impossible at home.

Grinding of rubber products on specialized lines for a full processing cycle. This method is used in industrial production, where the production of crumb rubber is carried out in large quantities and requires large financial investments.

Rubber processing at home using homemade units (crushing machines). Having milling and welding equipment, you can make a chopper with your own hands. If this is not possible, parts can be ordered from the workshop according to personal designs. The cost of a crusher made independently is much cheaper than ready-made equipment.

Regular recycling of waste rubber requires a well-ventilated and spacious area to install equipment and store large quantities of rubber waste. The location of the premises in an industrial zone will be a plus.

Unit design

The design of the shredder is a knife mechanism (shredder), which allows you to process tires, tubes and other rubber elements. With this method of grinding, the material retains its molecular formula and does not lose its elasticity. The performance of equipment depends entirely on its power rating.

Main components of the rubber processing unit:

Electric motor - ensures the speed of processing rubber waste, recommended engine power is 4-5 kW.
Box with cutting discs - crushes raw material to the required size.
Crumb calibration grid - regulates the diameter of the resulting crumb rubber.
Worm gear – eliminates jamming and jamming of material.
Unit frame - ensures a stable position of the machine.
Loading hopper
Guide tray

The entire mechanism of the machine is placed in a housing, on top of which a loading hopper is installed. Before loading the material, foreign objects must be removed. metal objects(spikes, nails, etc.). Tires are cut into strips, reducing processing time.

Box with cutting discs

The main part of the unit is a shredder unit. The box contains heat-treated steel milling discs of high strength. They are quite wear-resistant and do not require frequent replacement during operation of the machine. Manufacturing the structure requires precise calculation of holes and cutting discs, so the work should be entrusted to the designer.

Grid for calibrating crumbs

A calibrating grid is installed under the box with the milling shafts, which allows you to adjust the diameter of the crumb rubber obtained when shredding tires in a shredder.

Worm gearbox

Mechanical gearbox converts angular velocity using a worm gear and allows you to process rubber material of varying elasticity without winding or freezing. Mechanical transmission rotational movement can be set in the range from 25 to 35 units, ensuring high performance of the unit.

Unit frame

Safe operation is guaranteed by the machine frame, made of profile materials. It ensures a stable position of the unit during the period of crushing and loading of raw material.

Loading hopper

The machine is equipped with a hopper for loading tire raw materials, which for convenience is located on the top of the body and a guide tray. They ensure a uniform flow of raw material into the shredder (shredder), preventing the formation of congestion during operation.

Tire cutting device

To cut tires and remove metal cord, a structure of a rack and a supporting frame is used. The housing contains a bar clamping system, which rotates together with the bar during cutting. The rack of the structure is equipped with a wedge-shaped knife that can be adjusted to a specific tire size. This design installation technology saves time on preparing consumables for further grinding in a shredder.

Tire shredding

The technological process of grinding involves the following procedure:

Sorting of tire raw materials and removal of foreign metal (nails, spikes, etc.)
Removing metal cord
Cutting tires into strips
Shredding raw material in a shredder
Calibration of the resulting crumbs

Recycling

Crumb rubber is widely used in various areas of production, sold to the public or used for personal purposes. Excess of deteriorated car tires and rubber products ensures constant availability of consumables.

The cost of crumb rubber depends on the diameter and quality of the granules. Powdered crumbs and granules with a diameter of 2-4 mm are in great demand. The popularity of this size is due to lower production costs and lower consumption of adhesive, the price of which is several times higher than the cost of recycled materials.

Crumb rubber is used to make the following products:

Roll coverings
Rubber Shoes
Paving slabs
Fuel
Rubber insulation and seals
Three-dimensional figures cut from used tires
Paths for private houses, gardens and summer cottages
Waterproofing and noise-absorbing coatings for children's and sports grounds
Rubber technical products
Asphalt mixtures
Seamless rubber coatings

Currently, the recycling sector is considered promising for opening own business due to low competition and growing demand for waste recycling services. Even with a small amount of work performed, the financial investments spent on equipment pay for themselves in a short time. Recycling tires in a crusher is recognized as the most environmentally friendly in a safe way recycling, allowing you to make a profit with small financial investments.

Enterprises involved in the production of rubber elements, tires, tubes and other similar products often use rubber shredders.

They allow you to recycle tires, tubes and other elements made of rubber. The material remains flexible and elastic, retaining its molecular formula

How to choose the right crusher

You should choose this type of equipment based on the following parameters:

build quality;
high-strength knife metal that can withstand constant heavy loads;
overall dimensions of the device;
dimensions of the receiving neck;
engine power.;
maximum amount of processed material per hour.

Taking into account all the above points, you can choose a crumb rubber shredder for your specific tasks. Engine power should not be neglected. By overloading it with constant actions, it will not cope with the required volume of material that needs to be processed and will experience regular failures and breakdowns. In addition, our company offers tire recycling lines.

Before tires go into the shredding container, they must be cut. Rubber tire parts instantly turn into crumbs, significantly saving you time and money on more expensive equipment.

High-quality work of the shredder will give you undamaged, flexible and elastic crumb rubber. Parts and elements of high quality and strength are produced from recycled materials.

One of the environmental problems is the disposal of used tires. Improper disposal of rubber causes irreparable harm environment and human health. Recycling recyclables using a tire shredder can help solve this issue.

It has long been known that worn-out tires that are out of service are a potential source of environmental pollution and environmental damage. Processing tires into crumbs at home is just as popular a method as the factory ones. Rubber waste from used tires is virtually non-biodegradable and takes hundreds of years to decompose.

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, it is imperative proper disposal, namely waste recycling. Without constant recycling, an environmental crisis could occur very soon.

Recycling

Recycling is also economically beneficial. From car tires you can get different kinds valuable recyclable materials, as well as produce a huge amount of finished products. From waste rubber powder of a very fine fraction (about 0.2 mm) new car tires and rubber shoes are produced; this secondary resource is popular in Russia and the CIS countries.

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

Particularly active and advanced people have the opportunity to recycle rubber with their own hands. What is needed for this? Used tubes, tires, tires and a little ingenuity. Recycling tires into crumbs at home is quite a complex undertaking. In terms of their properties, tubes from old tires are more suitable. They are softer and more easily susceptible to external influences.

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 shredder 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:

Preliminary preparation of tires. Initially, they are washed and cleared of impurities, after which they are transported by conveyor to the primary crushing unit, where they are ground by knife crushers to large pieces (30-50 mm).
At the second stage of the technological process, the primary processed raw materials are fed using a belt conveyor into a hammer crusher, where they are crushed a second time to smaller sizes (10-20 mm). It is at this stage of processing that the metal and textile cord and bead wire are separated from the rubber. Textiles are separated by a special textile removal system, and metal is separated by a magnetic separator. The collected metal waste is then briquetted.
At the final stage, processing into crumbs is already carried out. An extruder is used as equipment for processing tires into crumbs, a grinder in which the rubber mass is ground into a fine powder. At this stage of tire processing, additional cleaning of the crumbs from textiles and metal is also carried out using a gravity separator. After this, the crushed rubber crumb is divided into fractions and packaged in 20 kg polyethylene bags or big bags (soft containers) with a carrying capacity of up to 1000 kg.

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

Chemical processing method

With the chemical treatment method, car tires undergo pyrolysis. With this processing method, thermal decomposition of rubber occurs constituent elements. The tires are first crushed into a homogeneous mass and sent to the oven, where they decompose at a temperature of 500 - 800 °C. This procedure lasts 10 - 20 minutes. During the thermal decomposition of rubber, about 50% hydrogen and 26% methane are formed, as well as solid pyrolysis products, which are then used in cleaning Wastewater at wastewater treatment plants in Russia.

There is also an effective, but expensive physical and chemical method for processing tires into crumb rubber - cryogenic grinding of car tires. Rubber crushing is carried out in a special cooling chamber under extremely low temperatures(up 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.

Nowadays, there are many mini-factories for processing tires. The business plan for recycling car tires is quite simple. To implement it, you will need modern equipment for processing car tires, equipment for warehouses, fuel tanks, tools and clothing for workers, as well as the cost of installing equipment. Registration of the enterprise and a license that will allow you to engage in this type of activity are required. To start this business you will need significant start-up capital.

Every year, thousands of tires are lost in landfills and landfills, despite the fact that for an enterprising person they are a 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 is worth considering purchasing your own tire recycling equipment.

However, not everyone can afford a full-fledged 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.

Recycling small amounts of rubber at home

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

All you need is scissors and a 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 cord removal and subsequent rubber grinding.
Processing using universal crushers, which can be done at home yourself.

The first two methods require large investments. The third option is available to anyone who has the opportunity and desire to make a crusher at home.

The necessary units can be made independently in a workshop or at a production site - where there are metal-cutting machines (lathes, milling) and welding machine for the manufacture of components.

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.
