Abstract: A shredder device including a feed hopper, a screw conveyor and a shredder module, wherein the screw conveyor includes a screw conveyor shaft driven by a screw conveyor motor unit and having a screw conveyor flight formed thereon, and the shredder module includes a cutting drum having cutting openings formed therein, and a main screw rotatably arranged in the shredder module and having a main screw shaft, which is driven by a main screw motor unit, and a main screw flight which is formed thereon and passes over the cutting openings. The shredder device enables a higher cutting capacity. The main screw shaft is coaxially enclosed by the screw conveyor shaft inside the feed hopper up to the shredder module.
