Abstract: The invention relates to a process for separating tenaciously elastic materials such as plastics and rubber from materials tearing and/or defiberizing under high mechanical stress, particularly paper, and to a device for performing said process. The process is characterized in that the mixture of materials to be separated is subjected to high radial, axial and tangential acceleration forces, whereby a mass flow of shredded fibrous material and a mass flow of substantially unshredded plastics is withdrawn separately. The device for performing the process consists of a screen basket which is cylindrical or preferably polygonal in shape and has borings in its jacket to let the defiberized material pass through, a rotatable driving shaft being arranged coaxially inside the screen basket, with blades being attached to said driving shaft, preferably in rigid connection.

Abstract: A process and apparatus for reprocessing mixed plastics, more particularly mixed plastics from household refuse. The material being reprocessed is shredded in a shredding stage, agglomerated in an agglomerator wherein volatile substances are sucked off by suction devices, and the agglomerated material is dried over a drying path. In order to reduce obstructive substances, such as paper and ash, the fine grain portion in particular of the plastics agglomerated is screened off. With the drying process it is possible to produce without wet processing steps which are high in energy consumption a plastics agglomerate of high quality which is suitable for industrial re-use.
