摘要： The invention relates to a method for the recycling of plastic-coated cable residues, which comprise a metal core and a plastic jacket, wherein the metal parts are separated from the jacket and are separately recovered. The cable residues are communited and the chopped material is softened in a swelling container (10) with a swelling agent for the plastic. Subsequent to softening, the mass flow is fed with the swelling agent to a roller cone mill (13). The roller cone mill (13) flexes the chopped material and destroys the macrostructure of the cable pieces mechanically. The metal particles are separated from the jackets by way of stirring in a stirrer (14), and the multi-phase mixture is transported to a metal sedimentor (16). The heavier metal particles sink down in the metal sedimentor (16) based on gravity and separate themselves from the lighter plastic particles. The transport speed of the transport flow in the metal sedimentor (16) is selected such that the metal particles corresponding to their size-dependent different sinking speeds sink up to the outlet out of the metal sedimentor (16). A countercurrent of swelling agent is entered into the transport flow, where the countercurrent discharges the lighter plastic particles from the transport flow. Thereupon, the countercurrent with the plastic particles is led out of the metal sedimentor (12) as a partial flow and is led into a plastic sedimentor (38) for the sedimented depositing of the plastic particles. The method is performed sealed against gas and the swelling agent is cyclically recovered.
