The working principle of the plastic crusher is mainly to rely on the blade to impact, crush and shred the plastics. For example, a high-speed rotating shaft and specially designed blades can quickly crush large pieces of plastic into small pieces. This equipment performs well in the treatment of plastic films, industrial plastics, plastic pallets, large pieces of plastic rubber and wasted plastic bottles. It can efficiently recycle waste plastics for reuse, reduce dependence on new raw materials, and save production costs.
