Types of plastic granulation equipment

Based on the number and structure of the screws, plastic granulation equipment is mainly divided into two categories: single-screw extruders and twin-screw extruders. Single-screw extruders have a simple structure and lower cost, making them suitable for granulating general plastic raw materials. Twin-screw extruders, on the other hand, have stronger mixing and plasticizing capabilities, enabling them to process more complex plastic raw materials, such as modified plastics containing fillers and reinforcing fibers. Therefore, they are more widely used in high-end plastic granulation.

Plastic granulation equipment is an indispensable key piece of equipment in the plastics processing industry. Its main function is to transform recycled plastic waste or virgin plastic raw materials into granular plastic through processes such as melting, extrusion, and cutting, facilitating subsequent processing.
