Abstract
A machine and method for pulverizing solid polymer materials into smaller particles uses a pulverizer head having a rotor with a conical contact surface and a stationary dish with a corresponding inverted conical contact surface. The dish and rotor are axially aligned and spaced apart to define a gap of fixed width between them. The material is conveyed into the gap at 0 PSI from a screw extruder. Rotation of the rotor generates shear forces within the gap that pulverizes the material, with the pulverized particles leaving the pulverizer head at the outer margin of the gap.
