Abstract

The invention relates to a processing device for, especially thermoplastic, synthetic material. The inventive device consists of a disintegration device and/or a conveying device having an upstream disintegration device and of a directly connected extruding device. The disintegrating/conveying device consists of a knife-carrying processor drum/conveyor worm (3/9) or a combination thereof. Said drum/worm circulates in a conveyor pipe/worm trough (6/38) in a driven manner. Said pipe/worm is provided with a supply opening (11) directed towards the top and an outlet (10). The processing drum (3) or the conveyor worm (9) and the extruder worm (8) are aligned with the longitudinal axes (17, 20) and the processing drum/conveyor worm (3, 9) is detachably and mechanically connected to the extruder worm (8) and both are driven by a transmission (31) and a driving motor (34). The outlet (10) of the conveyor pipe (6) and the inlet (23) of the worm pipe (22) are axially arranged directly one behind the other or are connected by means of a transition pipe (21).
