ABSTRACT:
A process for working up household, industrial and other similar waste for the recovery of a fibrous and/or granulated material, in which the waste material is subjected to preliminary comminution, magnetic separation, classification, drying and fractionation, wherein the light fraction resulting from the classification carried out after the magnetic separation is subjected to secondary comminution by cutting, and the heavy fraction to a predominantly granulating secondary comminution and thereafter both comminution products are recombined, dried and fractionated into fibrous matter and granulated material, is to be simplified, and in particular the costs reduced. This is achieved in that before the secondary cutting comminution appliance at least one part stream or the whole stream of the light fraction is diverted and fed directly and/or after comminution in a further comminution unit to further utlization. A device for carrying out the method is also proposed.
