Abstract

In a method and equipment for conditioning low-metal scrap high in plastics, which contains at least partially scrap high in plastics from shredder processes, especially of scrap vehicles, the method includes: splitting up ferromagnetic components from the scrap that is high in plastics; separating a first raw sand fraction from the scrap high in plastics that has been reduced in metals; reducing in size the fraction high in plastics that remains after the isolation of the first raw sand fraction; separating a second raw sand fraction after reducing in size the remaining fraction high in plastics; and splitting up the remaining fraction, that is high in plastics, into a light fraction and a heavy fraction.The equipment has the appropriate device for carrying out the individual method steps.
