[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can undergo large deformation under very small external forces, and can return to its original state after removing the external forces. Rubber belongs to a completely amorphous polymer, and rubber products are widely used in various aspects of industry and life.

[0003] By using machinery to slice the rubber block raw materials and melt the rubber and then feeding it into a rubber granulator, the rubber raw materials can be made into rubber particles, so as to carry out further processing.

[0004] In the prior art, after the granulator collects the rubber particles, the temperature of the rubber particles is still relatively high because they have not been heat-dissipated, so that the rubber particles are likely to stick together due to the high temperature, thus affecting the product quality of the rubber particles. Summary of the Invention
