PC Engineering Plastic Granulator

Product Overview

The PC engineering plastic granulator is a single-screw, specialized recycling granulation machine designed for rigid plastic sheet materials. It is tailored for pre‑crushed rigid plastic fragments and can directly process these materials in an integrated granulation workflow, producing uniform, stable recycled pellets. The equipment is compatible with various rigid plastic wastes such as HDPE, PP, ABS, and PC, offering a broad capacity range of 100–2000 kg/h. Its main motor power spans 30–355 kW, supporting continuous 24‑hour operation. Finished pellet impurity levels are ≤1%, and particle size uniformity reaches ≥95%, making it an efficient core device in the field of rigid plastic recycling and regeneration.

Technical Principle

This equipment employs a single‑screw extrusion process with a clear and efficient material flow: pre‑crushed rigid plastic sheets are fed directly into the hopper and then into the barrel. Segmented ceramic heating bands precisely control temperature, while shear friction generated by screw rotation ensures thorough melting and plasticization of the rigid plastics. The molten material passes through multi‑stage filter dies to remove sand and impurities, complemented by venting systems that eliminate moisture and volatile components, guaranteeing high purity. Finally, the plastified material is water‑cooled and shaped before being cut into uniform recycled pellets by the pelletizing system. This integrated process enables direct processing of crushed materials, efficient impurity filtration, and complete moisture removal, ensuring high quality and stability of the final pellets.
