ROTOR GRINDER Russian patent published in 1997 - IPC

FIELD: rotor grinders. SUBSTANCE: aim is to increase effectiveness of material grinding process. Proposed grinder main and additional rotors disks are in pairs linked to each other by differential gears providing opposing rotation of neighboring disks with doubling of relative speeds of rotation using only one common drive, Proposed compact system of stream deducting has only one common drive. The system uses natural vibration of grinder body (without usage of individual drive for filtering fabric shaking). Plate with impact pins on upper disk blades is used for large lumps auxiliary grinding. To provide required grinding fineness lower part of body has perforation and rotor - with set of pushers and radial blades on rotating tray. EFFECT: increased effectiveness of material grinding process. 2 dwg, 1 tbl
