ABSTRACT:
An apparatus for comminuting commercial and industrial waste, particularly for comminuting paper, wood, plastics, etc., with a material loading chamber, as well as a material outlet region with a receiving container having an outlet opening for the material to be comminuted and with a comminuting mechanism, which is disposed in the receiving container and comprises a comminuting tool that can be caused to rotate by means of a drive motor. In order to create, particularly with a reduced construction and design effort, a comminuting apparatus, with which material can be comminuted effectively to a predetermined extent, the comminuting mechanism comprises at least two, essentially coaxially disposed comminuting tools one of which can be caused to rotate by means of the drive motor, the other of which, on the other hand, is disposed to be stationary or to rotate at a low rotational speed. Moreover, one of the comminuting tools has classification form recesses which are open towards the other comminuting tool. The other comminuting tool has at least two pocket recesses which can be connected with the classification form recesses, one pocket recess being assigned to the material loading chamber and the other pocket recess being assigned to the material outlet region.
