Abstract
A device for compacting loosely packed materials, in particular synthetic materials, comprises a shredder/conveyor rotor body arranged in a casing and drivable with the rotation around an axis of rotation and a consecutively arranged extruder with an extruder screw that is arranged rotatably and coaxially to the shredder/conveyor rotor body. Materials supplied to the shredder/conveyor rotor body are conveyed to the extruder screw, whereby they optionally are shredded. According to the invention, the shredder/conveyor rotor body is configured as a hollow body open at the front side opposite the extruder and has at least one rotary bearing in its interior, which rotary bearing rests on an abutment body projecting from the open front side into the interior of the shredder/conveyor rotor body.
