METHOD AND APPARATUS FOR DRYING WET POLYMERIZED MATERIALS Abstract of the Disclosure A method and apparatus for drying wet polymeric material wherein, after being compressed and heated in an extruder barrel, the material is extruded to form crumb through orifices in a multi-orifice die plate equipped with a rotatable die face cutter. The invention effects movement of some of the polymeric material across the downstream end of the extrusion screw constantly to replace the material between the end of the screw and the cutter mounting thereby preventing a stationary zone of the material or slowing down in movement of the material and hence avoiding its degrada- tion through overheating.
