Abstract: A comminuting plant is equipped with a comminuting machine for the coarse comminution of bulky material, and a granulating machine for the fine granulation of the precomminuting material from the comminuting machine. The comminuting machine includes at least two parallel shafts having several rotary bodies arranged on each shaft to provide cutting disks. Between the cutting disks in each case, there are arranged separate spacers. The spacers are smaller in diameter than the cutting disks, and turn with the shafts in such a way that the cutting disks of adjacent shafts cooperate, as the cutting disks touch each other in rotation, at least intermittently in the zone of their facing cutting edges. The circumferential surfaces of the spacers provide interspaces for the passage of the comminution material.
