ROTOR HYDRAULIC GRINDER Russian patent published in 1997 - IPC

FIELD: comminution and dispersion of fine-grained materials with usage of hydraulic water hammers and hydrodynamic cavitation used in mining, building industries, in process schemes of benefication mills and in power industry in equipment of solid fuel preparation for burning. SUBSTANCE: bulges 14, 15 and pits 12, 13 are made so, that during their mating blades are formed, that are extension of blades of operational wheel 6 with clearances equal to initial material maximum grain. Movable disk 5 bulges 15 and pits 13 are moving at great speed breaking pulp flow, cutting its continuity and forming cavitation zone. At the moment of stationary disk 4 and movable disk 5 pits 12, 13 and bulges 14, 15 instant mating blades are formed, that are extension of operational wheel blades 6, that pump-feed pulp and created in cavitation zone additional hydraulic hammers intensifying process of solid particles comminution. EFFECT: improved design and process. 3 dwg
