ABSTRACT:
The thermoplastic resin waste containers are crushed into coarsely crushed pieces, an impact-grinding force and a centrifugal force are applied on the coarsely crushed pieces so that oily foreign objects be separated; i.e., the oily foreign objects are separated by the impact force and the grinding force. The difference in the centrifugal force separates the resin from the foreign object, the centrifugal force on the resin pieces being controlled by the impact-grinding force, while the centrifugal force on the oily foreign object is free from it. In the course of this process, the crushed pieces to be treated are formed into granules by the impact-grinding force, and the granulated granules are reused as a resin material. Foreign objects other than oils can be separated and removed more easily than oils.
