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.
Claims15
A method for comminuting composite materials and for separating the materials contained therein using a plurality of comminution and separation stages employing at least one hammer mill or rotor-impact mill, comprising:
- before the comminution of the material in the hammer mill or rotor-impact mill, performing a separation of already-comminuted composite material into a group including halogenated plastics, composite material, and metals, and another group including essentially halogen-free plastics, using x-ray transmission radiation to separate the two groups and sorting according to densities of materials, whereby the essentially halogen-free plastics being essentially sorted out.
