A recycled plastic pelletizing screw barrel must handle contaminated and uneven raw materials while maintaining stable feeding and plasticizing.

For PP, PE, HDPE and LDPE recycling, screw geometry should match the material condition, moisture, filler content, L/D, RPM and required output. Recycled materials can accelerate screw and barrel wear, especially when they contain CaCO3 or other abrasive fillers.

A wear-resistant bimetallic screw barrel can help extend service life and maintain stable extrusion performance.

If your recycling extruder has lower output, unstable pressure or poor plasticizing, it may be time to inspect the screw and barrel.
