PKM Pulverizer - PolyGrinder™

Pulverizing of brittle or tough plastics in a closed looped system for free flowing powders to be used for extrusion, rotomolding, and coating applications.

Method of Operation

The material in granular form is fed with a vibratory feeder from a feeding hopper to the pulverizer.  The material is pulverized between the two rings of segments mounted on carrier discs, then air conveyed to a screening machine.  The coarse material is recycled to the pulverizer for further size reduction.  The desired powder is diverted to fill bags or containers, or conveyed to silos.  A one pass system, without a sifter is also available.
