PROCESS AND DEVICE FOR THE SEPARATION OF VISCOPLASTIC MATERIALS SUCH AS PLASTICS FROM MATERIALS SUCH AS PAPER WHICH CAN BE DEFIBRATED BYMECHANICAL ACTION

摘要

A process and a device are provided herein for the dry separation of viscoplastic elastic materials from fibrous materials which defiberize under mechanical stress. The viscoplastic elastic materials and the fibrous materials are present essentially as composite materials. The method includes defiberizing the composite materials under mechanical stress. Thus the materials to be separated are subjected to high acceleration and impact forces in radial, axial and tangential directions. The mass of defiberized fibrous material and the mass of viscoplastic elastic materials in the mass flow of non-shredded viscoplastic elastic material and defiberized fibrous material is withdrawn separately from the mass of viscoplastic elastic materials which are in an essentially non- shredded state.
