<p>A device for reprocessing, that is to say for disintegrating, used packaging materials, for example unsorted household paper, is described. The device essentially consists of a first comminution unit (14), a downstream trough-like housing (2) with an agitator (4, 6) rotating therein and a further comminution unit (18) located in the material outlet shaft (16). The device is also provided at its lower end with a heavy dirt collection chamber (26). The comminution units (14 and 18) are exchangeable and, depending on the processing requirements, it is possible to choose between purely cutting tools, more chopping or even disintegrating tools. The first comminution unit (14) serves for comminuting raw material with in part large surface area to give a conveyable size of pieces, while the second comminution unit (18) essentially serves for fine comminution and disintegration of the material. In the interposed trough, purification of the material can take place, it being possible to operate with washing fluid circulation via the connections (38, 34, 36 and 28). In this case, low-density stock operation is envisaged. The device can, however, also be operated in the high-density stock range, where disintegration can already start in the trough (2). The stock leaving the device has been pretreated in such a way that it can be separated by means of screen-sorting devices into its components which are to be treated further.</p> |
