Plastic Bucket Recycling Pelletizer

Product Overview

The plastic bucket recycling pelletizer is a single-screw, specialized granulation machine for rigid plastic flakes. It is designed to process pre-crushed rigid plastic fragments, enabling integrated processing from crushed material to uniform, stable recycled pellets. This equipment is compatible with various rigid plastic wastes such as HDPE, PP, and ABS, featuring a mature and reliable single-screw structure. It requires no additional crushing unit and can directly accept pre-crushed feedstock for production. The machine’s capacity ranges from 100 to 2000 kg/h, supports 24-hour continuous operation, delivers finished pellets with impurity content ≤1% and particle size uniformity ≥95%. With low operational complexity and outstanding cost-effectiveness, it stands as a core piece of equipment in the plastic recycling industry. As a custom product, pricing is not fixed; it will be tailored according to the customer’s specific production requirements.

Technical Principle

The plastic bucket recycling pelletizer employs a single-screw extrusion process, suitable for pre-crushed rigid plastic flakes. Material is fed directly into the hopper and enters the barrel for processing. Equipped with segmented ceramic heating zones, it precisely controls barrel temperature, while the shear friction generated by screw rotation ensures thorough melting and plasticization of the rigid plastic, guaranteeing uniformity and density. The molten material then passes through multi-stage filter dies to effectively remove sand, debris, and other impurities, followed by venting to eliminate moisture and volatiles, further enhancing pellet quality. Finally, the plasticized material is water-cooled and shaped before being cut into standardized recycled pellets via the pelletizing system. The entire process is highly automated, enabling continuous, stable, large-scale production.
