FIELD: technological processes.
SUBSTANCE: group of inventions is intended for activation of a suspension. At first shaft (5) of the device there is drum (4) with inlet (9) and outlet (1) holes. On the inner surface of the side and the end walls of the drum there are at least two side (11) and at least two concentric end (12) circular ledges, respectively. First and second (7) shafts are aligned with the possibility of differently directed rotation. At least two booster discs (13) are located inside the drum on the second shaft with partial overlapping of the side ledges. Booster discs are alternated with the side ledges. Additional disc (14) of the second shaft is provided with at least two circular shelves (15). Shelves partially overlap the end ledges and alternate with them. At the ends of the end ledges and the shelves there are boards (16). Boards are directed towards the center of the drum and form circular pockets (17). Suspension fills the end ledges and the shelves pockets from the center to the periphery of the drum forming annular layers of grinding. Opposite collision of solid particles of the suspension with the grinding layer grinds them. Turbulent zones of auto-grinding between the booster discs and the side ledges provide additional grinding.
EFFECT: provided is higher efficiency of grinding and reduced wear of working members.
