Abstract: An apparatus for prewashing comminuted plastic parts and for separating heavy materials or mineral constituents such as sand, silt, etc.

Abstract: The invention relates to a device for comminuting feedstock (1) of any type, in particular made of plastic, preferably of PE, comprising a feeding apparatus and a comminuting apparatus (6), wherein the feeding apparatus (2) comprises a trough (3) to receive the feedstock (1) and conveying means (4) for conveying the feedstock (1) to the comminuting device (6) or into the comminuting device (6), and wherein the comminuting device (6) comprises a planar tool holder (9) equipped with tools (10), in particular cutting tools, on its operating side, characterized in that the tool holder (9) performs an oscillating motion relative to the feedstock (1).

Abstract: The invention relates to a method for pre-cleaning parts made of plastic as part of a recycling process, wherein foreign bodies to be removed adhere to the parts, in particular for removing foreign bodies on parts made of plastic, preferably for removing labels, dirt, etc. on used plastic bottles, said method being characterized in that the foreign bodies are removed from the parts by mechanically loading the parts. A device for applying the method is characterized by a housing (2) having a chamber for accommodating the parts, means (3, 4, 11) for mechanically acting upon the parts and means for separating the foreign bodies released from the parts and for discharging the foreign bodies and parts onto separate paths being provided in the chamber.

Abstract: The invention relates to a device for comminuting all types of parts, in particular plastics, preferably hollow plastic bodies, such as for example plastic bottles. The device comprises a feeding device, and a comminuting unit, the feeding device having at least one transport unit and the comminuting unit having a rotor, which is provided with tools and rotates in a housing. The device is characterised in that the transport unit transports the parts at an angle of between 45° and 90° to the rotor axis, at least in the region lying directly in front of the rotor.
