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. The granulating machine includes at least two shafts disposed in one plane and at least two further shafts arranged in another plane, preferably parallel to the first plane, several rotary bodies being arranged on each shaft to provide granulating disks, each disk having a toothing. Between the granulating disks in each case, there are arranged separate spacers. The disk spacers are smaller in diameter than the disks, and are turnable with their respective shafts in such a way that the granulating disks of one shaft are engaged between the granulating disks of at least one shaft lying in the same plane and of at least one of the shaft lying in the other plane at least to a depth greater than the depth of the toothing in the disks.
