  • Patent number: 5908165
    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.
