An apparatus is described for reprocessing, i.e. disintegrating, used packing materials, for example unsorted domestic waste paper. The apparatus consists essentially of a first comminuting aggregate (14), a following trough-like housing (2) with agitating mechanism (4, 6) rotating therein and a further comminuting aggregate (18) arranged in the material exit well (16). The apparatus is further provided at its lower end with a heavy trash collecting chamber (26). The comminuting aggregates (14 and 18) are replaceable and depending upon the working requirements selection is possible between purely cutting, more chopping or also disintegrating tools. The first comminuting aggregate (14) serves to comminute the largely sheet-like raw material to a conveyable piece size while the second comminuting aggregate (18) serves essentially for fine comminution and disintegration of the material. In the intermediate trough cleaning of the material can take place, and a rinsing liquid circulation can be employed via the connections (38, 34, 36 and 28). In this case low-density operation is provided. The apparatus can however also be operated in the high-density range and then a disintegration can start in the trough (2) itself. The material leaving the apparatus is prepared in such a manner that it can be separated into its components to be further treated by means of sieve sorting devices.
