Plastic recycling granulator screw cylinder

Single screw

Simple structure, suitable for granulation of thermoplastic materials such as PE and PP, commonly used in the processing of small and medium-sized recycled plastics

Plastic pellet machine is a specialized equipment that melts and extrudes plastic raw materials or waste materials and cuts them into pellets. It is widely used in the fields of plastic recycling, modification, and product production. The following is a comprehensive information compilation:

1、 Equipment classification and core structure

By screw type

Single screw granulator: suitable for simple granulation of thermoplastic materials such as PE and PP, with a simple structure and low cost.

Twin screw granulator: suitable for complex processes such as high filling and blending modification, such as PVC and masterbatch production, with high torque and modular threaded component design

Core components

Extrusion system: including screw (high-strength alloy steel), barrel (heat-resistant composite steel pipe), head (oblique/right angle design) and mold.

Transmission system: motor-driven, equipped with reducers and bearings, supporting variable frequency speed regulation.

Heating and cooling system: electric heating with segmented temperature control, supplemented by water/air cooling devices
