[0002] The recycling and reuse equipment for waste plastic products can crush waste plastic products into small particles for subsequent processing. It can handle plastics of different hardness and thickness. After crushing, the volume of the plastic is greatly reduced, which improves the space utilization rate during transportation and reduces transportation costs. It is suitable for different types of plastics (such as PE, PP, PVC, etc.) to meet diverse recycling needs. It is easy to operate and maintain, and greatly reduces labor costs and operating difficulties.

The environmentally friendly plastic waste recycling and reuse device can fully crush the waste plastics into granules, and then automatically recycle the waste plastics, reduce the labor intensity, and facilitate recycling.

[0004] Existing waste plastic product recycling and reuse processing equipment is often not convenient for effective screening of crushed plastic particles when in use. During the plastic crushing process, larger plastic particles are easily produced, resulting in inconsistent particle sizes.
