ABSTRACT:
A roll crusher for discarded storage batteries or other types of bulky scrap has two rotors provided with axially spaced-apart annuli of teeth which cooperate with rows of teeth provided on a grate normally adjacent to the undersides of the rotors. The grate is pivotable about an axis which is closely adjacent to, parallel with and disposed at a level below one of the rotors so that it can assume an inoperative position in which it extends substantially vertically downwardly and each of its sides is readily accessible for cleaning, replacement or inspection of its teeth. The teeth of the grate are disposed in rows and each such row of teeth is integral with a discrete plate-like carrier which is removably inserted into the frame of the grate so that it can be expelled or withdrawn if the treated material is not readily detachable from the teeth of the grate while the grate dwells in the inoperative position.
