Background

The rubber material has excellent viscoelasticity, high elasticity, electric insulation property, durability, solvent resistance and other performances after vulcanization, and is widely applied to life and production of people, wherein the rubber material is most used in the aspects of automobile tires, rubber shoes and the like. With the rapid development of the industry and agriculture of China and the transportation, the consumption of rubber is larger and larger, and the waste rubber is more and more. Because the waste rubber cannot be naturally decomposed, a large amount of waste rubber is accumulated, and a large amount of waste tires are accumulated and improperly treated, so that the waste of resources is caused, and the environment is seriously polluted, and the black pollution is caused. The waste tires are properly treated and resources are recycled, so that the environment can be protected, and sustainable development can be realized.

The waste tires are crushed by a mechanical method, so that the waste rubber can be recycled. In the process of mechanically crushing rubber, the service life of the crushing knife can be seriously influenced by high heat generated by long-time friction between the crushing knife and the rubber; and the rubber is melted at high temperature and can be adhered to the blades, thereby influencing the crushing effect of the crushing blades.
