PS Hard Material Recycling Granulator

Product Overview

The PS hard material recycling granulator is a single-screw recycling granulation machine specially designed for rigid plastic flakes. It can directly process pre‑crushed plastic fragments without the need for an additional crushing unit, enabling integrated granulation operations. The equipment is compatible with various rigid plastic wastes such as HDPE, PP, and ABS, producing uniform and stable recycled pellets with impurity content ≤1% and particle size uniformity ≥95%. With a capacity range of 100–2000 kg/h, it supports 24‑hour continuous production, making it an efficient core device in the field of rigid plastic recycling.

Technical Principle

This equipment employs a single‑screw extrusion process optimized for pre‑crushed rigid plastic flakes. After direct feeding into the hopper, the material enters the barrel, where segmented ceramic heating bands provide precise temperature control. Combined with shear friction generated by screw rotation, the rigid plastic is thoroughly melted and plasticized, ensuring uniform plasticization and high pellet density. The molten material then passes through multi‑stage filter dies to remove sand and impurities, while a venting system eliminates moisture and volatile components, effectively reducing impurity levels in the final pellets. Finally, the extruded strands are water‑cooled and shaped, with pelletizing completed either via die face cutting or strand cutting, guaranteeing particle size uniformity ≥95%.
