Problems solved by technology

[0042] This study also demonstrates that although the combination of screw speed and barrel temperature can selectively break crosslinks, because the method has a constant barrel temperature measured at the head of the extruder and has no effect on the internal temperature of the extruder screw. control, so severe degradation may occur

Abstract

The present invention generally relates to comminution of polymeric materials. More specifically, the present invention relates to extrusion methods and apparatus for the production of granular deformed polymer particles having a more useful final desulfurization surface area for downstream industrial use. In particular, the present invention relates to comminutive extrusion methods and apparatus that use the specific combination of variable feed screw torque and variable main screw speed described herein along with the combined extruder barrel and extruder main screw temperatures control.

Description

technical field [0001] The present invention generally relates to the deformation of polymeric materials into granules by crushing extrusion. More specifically, the present invention relates to an extrusion process and apparatus for the production of granular deformed polymer having a more useful final desulfurization surface area for downstream industrial use. In particular, the present invention relates to comminutive extrusion methods and apparatus utilizing the specific combination of variable feed screw torque and variable main screw speed described herein along with the combined extruder barrel and extruder main screw temperatures control. [0002] While it will be convenient to describe the invention with reference to the processing of end-of-life rubber products such as used tires and used rubber conveyor belts, the invention is not limited to this application and may be used to process other types of waste polymeric materials. [0003] The term "waste" polymeric mat...
