Technology grinding and pulverization

The pulverization techniques for rubbers are also being developed based on the concept of polymer pulverization originally proposed for plastics. The process manufactures polymer powder using a twin-screw extruder imposing compressive shear on the polymer at specific temperatures that depend on the polymer (Enikolopian, 1985). Based on this method, the solid-state shear extmsion pulverization method of rubber waste is also proposed (Khait and Torkelson, 1999 Khait, 1994). The obtained rubber particles were fluffy and exhibited unique elongated shape.
