Description

Technical Field

[0001] The present application relates to the technical field of rubber crushing, and in particular to a low-temperature environmentally friendly crushing device for waste rubber. Background Art

[0002] Rubber is an important strategic material, and China's external dependence on rubber is as high as more than 50%. With the development of China's economy, especially the development of the automobile industry, China's demand for rubber tires is increasing day by day. Now China has nearly 300 million vehicles of various types, consuming a huge amount of rubber every year. Therefore, not only is a large amount of imports needed to meet market demand, but also a large number of waste tires are produced every year, increasing the environmental load. According to relevant data, China produces about 300 million waste rubber tires every year, about 20 million tons. Among them, only a part is recycled, and more waste tires need to be processed. Therefore, how to solve the recycling and management of waste tires in China is an important task facing the rubber industry and environmental protection. Waste tires can be made into rubber particles after slicing and freezing and crushing. Rubber particles can be used to lay artificial turf, enter the rubber industry as a recycled raw material, and be used as a material for laying horse pens and racecourses. Frozen crushing utilizes the mechanical fragmentation of rubber materials when they are far away from the glass transition temperature. There is no relative displacement between the rubber powder molecules produced by the freeze-crushing method, and there is no change in the microscopic morphology. Therefore, the freeze-crushing retains the original rubber properties, especially the elasticity, to the maximum extent. During the freeze-crushing process of rubber, there is no degradation of the polymer at the microscopic level, neither thermal degradation nor chemical degradation.
