Abstract

In a method and equipment for conditioning a heavy fraction high in plastics, which is obtained by conditioning low-metal scrap high in plastics, which originate at least in part from shredder processes of scrap vehicles, the method includes: isolating metal parts from the heavy fraction high in plastics; reducing the size of the metal-reduced heavy fraction high in plastics that remains after the isolation of the metal parts; splitting up of the metal-reduced heavy fraction high in plastics, that remains after the isolation of the metal parts, into fractions high in plastics having different grain sizes; conditioning the separated fractions high in plastics at least partially in separate processes. The equipment includes appropriate devices for carrying out the foregoing processes. A highly pure granulate fraction may be obtained, which may be fed to material utilization.
