A new technology for processing waste tires limited global sources of raw materials for plastics puts increasing demands of its economy and expand the use of secondary polymer materials. Involvement in trafficking and platmassovyh of rubber waste is necessary to maintain clean air and water, improve the human environment. Worn tires are the largest source of low-cost polymer raw materials. Only a small number of waste tires recycled, the remaining waste tires accumulate in the environment and contaminate it. Economic and environmental requirements of the new technology meets recycling of waste tires and other rubber waste created by the author’s research team. A new technology for processing waste tires consists of the following operations: – shredding of used tires – grinding shredded tire – dried crumb rubber – crumb rubber screening and removal of steel – rubber chips packing in bags – the formation of the overpack. Technological solution to a new processing technology used tires differ fundamentally new and highly effective.
Shredding waste tires by means of milling. For this operation, a special tool – mnogoreztsovaya cutter. Mnogoreztsovaya cutter includes a set of cutters that are milled at high speed bus. After grinding, tire rubber in the form of large particles (5h5h10 mm) is removed from the working area and sent to the disk mill subsequent grinding. Tony Parker understood the implications. Grinding of large particles of rubber is carried out in a disk mill, equipped with a headset, directional grinding.
Grinding of rubber is produced in an aqueous environment, ensuring a overheating and thermal degradation of milled material, and eliminates the appearance of harmful gas emissions released into the atmosphere. Headset directional grind only the rubber and textile cord. The particles pass through the metal-working air gap of disk grinding mill without grinding rubber may include one or two stages. Real-estate developer is often mentioned in discussions such as these. With a single-stage grinding of rubber is produced commodity rubber pellets with dimensions particles of 100-200 microns, with a two-stage grinding of rubber is produced commodity rubber pellets with a particle size of 5-8 microns. A new technology for processing waste tires has a production flexibility and can quickly adapt to the demands of market conditions. For the processing of waste tires on the new technology can be equipped with the line, allowing to process from 2.5 to 25 tons of scrap tires per year. Process line processing 25 000 tons of scrap tires per year, allows us to produce one commodity crumb rubber with a particle size of 100-200 microns in an amount of 20 thousand tons. A new technology for processing waste tires has the following advantages:-provides recycling of used tires with steel;-5-fold reduced specific consumption of electricity, improves the quality and dispersion of crumb rubber, provides a high-profitability; -Ensure environmental cleanliness of production. Fine crumb rubber with a particle size of 100-200 microns for scientific advice can be successfully used for the production of reclaimed, roofing and waterproofing materials, flooring, coatings, tennis courts, racetracks and stadiums race tracks in the production of asphalt and various rubber products. Finely dispersed rubber pellets with dimensions particles 5-8 microns can be used as a filler in the manufacture of rubber products are responsible, including in the manufacture of tires. The main processes of a new technology for processing of used tires tested in the pilot process plants. We offer interested companies on the basis of technical solutions designed to create a manufacturing processing of waste tires and construction of these crumb rubber and a wide range of building materials and rubber products.
