Claim:
Apparatus for comminuting synthetic plastic waste material, comprising a housing in which at least one rotor is bearingly supported for rotation by a motor around an axis, which rotor on its periphery is provided with comminuting tools acting on the supplied material, counter tools stationarily disposed within the housing forming a supply shaft of great volume being assigned to the comminuting tools, and further comprising a feed means having a slide member pressing the material disposed within the supply shaft against the rotor, the feed means comprising at least two slide members superimposed above each other and feeding the material to the rotor, which slide members are independently from each other moveable towards the rotor or away from it, wherein a front surface of a lowermost slide member facing the rotor defines with the tangent to the enveloping circle of the comminuting tools carried by the rotor a substantially wedge-shaped intake gap for the material to be comminuted, which intake gap narrows in a downward direction.
