FIELD: fibrous material grinding equipment.

SUBSTANCE: grinding set for disk mill has two disks assembled from sections and having working surfaces consisting of central ring with knives and peripheral ring with knives extending from center to periphery and arranged at an angle to radius of disk. Channels between knives on working surface of peripheral ring are covered with webs arranged on arcs eccentric relative to center of disks, which are inclined to radius r of disk at the same side as knives. Side surfaces of webs proximate to center of disks are beveled at an angle 30-60 deg relative to peripheral bottom surface. Height of working surfaces of webs protruding above said surface and of central knives is 0.4-0.6 the height of working edges of peripheral knives.

EFFECT: intensified grinding process, improved quality of grinding, increased capacity, and reduced consumption of power for operation of grinding set in idle mode.
