Abstract
A shredding module of a shredding apparatus is disclosed. The shredding module includes a shredder cassette receiver and a shredder cassette received within the shredder cassette receiver. The shredding cassette includes two shredding shafts arranged in parallel and rotatable about respective rotation axes, and two sets of fingers that cooperate with the two shredding shafts to shred material. The shredder cassette is slidably movable in an axial direction of the respective rotation axes into and out of the shredder cassette receiver.

A shredding module, comprising:
- a shredder cassette receiver;
- a shredder cassette received within the shredder cassette receiver;
- the shredder cassette including two shredding shafts arranged in parallel and rotatable about respective rotation axes, and two sets of fingers configured to cooperate with the two shredding shafts to shred material;
- the shredder cassette further including a front end plate and a rear end plate that rotatably mount the two shredding shafts;
- wherein the shredder cassette is slidably movable in an axial direction of the respective rotation axes into and out of the shredder cassette receiver;
- and
- a front drive module having a front mounting plate mounted to the front end plate of the shredder cassette;
- wherein the shredder cassette receiver includes a bore and a safety pin arranged in the bore, wherein the safety pin slidably engages into a groove on a radially outer surface of the shredder cassette to stop the shredder cassette at a predefined draw-out distance in the axial direction, wherein the groove extends partially along the radially outer surface of the shredder cassette in the axial direction from the front end plate towards the rear end plate;
- and
- wherein the front mounting plate, the front end plate of the shredder cassette, and the shredder cassette receiver are structured and arranged to be connected by bolts threaded through the front mounting plate and the front end plate and connected to the shredder cassette receiver.
