PE Pipe Crushing and Pelletizing Machine

Product Overview

The PE pipe crushing and pelletizing machine is a single-screw, specialized recycling pelletizing equipment designed for hard plastic sheet materials. It is specifically engineered to process pre-crushed hard plastic fragments, allowing direct connection to the upstream crusher without requiring an additional crushing unit, thus enabling integrated processing from crushed material to recycled pellets. The equipment is compatible with various hard plastic wastes such as HDPE, PP, and ABS, producing uniform and stable recycled pellets with impurity content ≤1%, particle size uniformity ≥95%, and a capacity range of 100–2000 kg/h. It supports 24-hour continuous operation and can be customized according to customer production requirements, making it an efficient core device in the field of plastic recycling and regeneration.

Technical Principle

This equipment employs a single-screw extrusion process, suitable for pre-crushed hard plastic sheet materials. Material is fed directly into the hopper and enters the barrel for processing. The barrel is equipped with segmented ceramic heating bands that enable precise temperature control. Combined with the shear friction generated by the rotating screw, the hard plastic is thoroughly melted and plasticized, ensuring uniform and complete plasticization. The molten material then passes through a multi-stage filtration die to remove sand, dirt, and other impurities, followed by a venting system that eliminates moisture and volatile components, further enhancing the purity of the recycled pellets. Finally, the molten material is water-cooled and shaped before being cut into pellets by the pelletizing system, yielding qualified recycled plastic pellets.
