Waste tires or used tires are tires that cannot be used; And it is an important issue in the mining industry and road construction companies. These companies, in order to reduce their costs and protect the environment, sell tires that cannot be reused due to wear and tear, so that these waste tires can be used properly.
Mineral waste tires (Damptrack and Loader)
Dump trucks and loaders, as heavy machines used in mines and road construction companies, need tires with high performance. However, due to the hard working conditions and the long distances that these machines travel, their tires also wear out quickly.
Mines and road construction companies, in order to reduce their costs and to protect the environment, look for There are solutions that can use the waste tires of dump trucks and loaders. These tires may be re-marketed as tires used in dump trucks and loaders through repair and retreading. And they may even be turned into granules and other materials for recycling, which we will discuss further.
Using dump truck and loader waste tires for recycling, in addition to reducing operating costs, the environmental impacts associated with tire disposal can be reduced. It also reduced wear and tear.
Recycling processes:
In tire recycling, various processes are performed to recover usable materials from worn tires. These processes are:
1- Thermal decomposition (pyrolysis): tires burn at high temperature without the presence of air and turn into materials such as hydrocarbon fuel (diesel), usable gases and black carbon, and the wire in the tire will also be collected at the end of the process. 2- Mechanical recovery (rubber granules and powder): tires are divided into smaller pieces and then recycled materials such as granules and iron wire are produced through special processes such as grinding. It will be.
Recyclable material:
In the rubber recycling process, various materials are extracted that can be reused. which includes the following:
Black carbon: Black carbon, which is obtained in the process of burning rubber, can be used in the production of new rubber, paints, coating materials and other products.
Pyrolysis oil : The oils obtained in the process of thermal decomposition, after distillation and final processing, can be used as fuels that can be used in the industry, which is called hydrocarbon fuel (diesel).
Mineral metals: metals present in certain processes They are recovered in worn tires (tire wire) like steel.
