Abstract
The present invention generally relates to polymeric materials pulverization. More particularly, the present invention relates to an extrusion method and device for producing particulate deformed polymers having a more useful resultant devulcanized surface area for downstream industrial usage. Specifically, the present invention relates to a pulverization extrusion method and device that utilizes the herein described specific combination of variable feed screw torque and variable main screw speed together with coupled temperature control of the extruder barrel and extruder main screw.
