Plastic Recycling Granules Screw

Heavy-duty screw barrel designed for recycled plastic granulation lines. Handles varied feedstock with consistent output and excellent wear resistance.

Product Overview

Vanwell recycling granulation screw barrels are built to handle the demanding requirements of plastic recycling operations. Our screws process mixed, contaminated, and varying-quality recycled materials with consistent throughput and granule quality.


Featuring a robust bimetallic barrel and specialized screw geometry, our recycling screws are designed to resist wear from hard contaminants, paper residues, metals, and mixed polymer blends. Available for all standard granulation line sizes from small laboratory units to large-scale industrial recycling plants.
