FEEDER-DISINTEGRATOR Russian patent published in 2003 - IPC

FIELD: feeders-disintegrators. SUBSTANCE: proposed feeder-disintegrator includes laminar belt, frame, baring rollers, tensioner and drive; secured in bearings on hold- down frame along laminar belt at clearance reducing towards discharge end are several rolls having serrated wear-resistant surface; diameters of said rolls reduce towards discharge end; hold-down frame is articulated on uprights and is provided with adjustable hold-down unit on discharge end. Rolls are provided with drive unit for their rotation in direction when lower generatrix of rolls moves in way of motion of laminar belt; speed of rotation of rolls having lesser diameter exceeds that of rolls having larger diameter. EFFECT: enhanced efficiency of disintegration. 1 dwg
