ABSTRACT:
The invention relates to a process for the comminution of composite materials, e.g. of electronics scrap, and also for the separation of the materials present therein, using a plurality of comminution stages and separation stages, with use of at least one hammer mill or rotor-impact mill (6), where, prior to the comminution of the material in the hammer mill or rotor-impact mill (6), a separation of previously comminuted composite material is achieved, into plastics on the one hand and composite material and also metals on the other hand.
