[0004] However, the existing raw material crushing devices for plastic product processing still have certain shortcomings: first, most of the existing raw material crushing devices for plastic product processing simply use a discharge pipe to discharge the crushed raw materials.

In addition, the single-level crushing process is affected by factors such as the plastic raw material's own material and the crushing space, which will cause the crushing to be incomplete, thereby causing the problem of differences in the particle size of the plastic particles.
