ABSTRACT:
Two rolls which carry roll teeth rotate, as seen from their top side, in directions away from their common roll nip or gap towards adjacent hopper wall sections which carry hopper teeth. The refuse is thus loosened instead of being compacted in the common roll nip or gap, as in the prior art. The loosened material is more readily cut than the material which hitherto was compacted in the common roll gap. At a predetermined limiting load between the roll teeth and the hopper teeth, at least the hopper wall section which carries the affected hopper teeth, is retracted from the associated roll by a drive and from its operative position depicted on the right in FIG. 2 into an inoperative position depicted on the left in FIG. 2. The interfering material can fall through downwardly, whereupon the hopper wall section returns towards the associated roll into its operative position. No hopper blockage can occur.
