ABSTRACT:
An apparatus for shearing and straining polymeric process material, such a scrap tires includes a rotor and barrel. Large material pieces are feed into a hopper and the material is warmed, pressurized and transported to a rotor--barrel transfer section to initially chop the material to reduce its size. The material then passes to a rotor barrier or refining section where the material must pass over wide top barriers that extend across extrusion grooves. The barriers included multiple ridges and the barrier to bore clearance is progressively reduced as the material passes downstream. Ramp like grooves, where rejected material can be worked further, precede the barrier ridges. A rotor to barrel transfer section, having a conical barrel that can be longitudinally shifted, follows the wide top barriers, so the size to the discharged material can be regulated.
