ABSTRACT:
The shredding unit comprises a horizontal drum mounted transversely within a cage having a front feed opening. Knives are rigidly fixed on the circumference of the drum which is partially surrounded by an evacuation grid having calibrated holes. In the active or work position, backing knives placed in alignment at each end of the grid and opposite to the drum project inwards from the grid while the knives of the drum pass in the immediate vicinity. Each backing knife is mounted at the extremity of a support plate and is capable of withdrawing under excessive pressure in opposition to a jack which urges the backing knife towards the active position.
