ROLL GRINDER Russian patent published in 1999 - IPC

FIELD: mechanical engineering; breaking and grinding of different materials. SUBSTANCE: roll grinder has conical driving and driven rolls fitted in bearing units. Driving roll bearing units are rigidly secured on frame, and driven roll bearing units are installed for displacement relative to frame owing to deformation of springs. Two pulleys-eccentrics set into rotation by motor through V-belt drive are installed on shaft of driven roll. Rolls are installed so that vertices of their cones are in opposite directions. Mass of eccentrics and summary mass of pulleys with eccentrics, driven roll with bearings are connected by relation-ships. EFFECT: enhanced efficiency of grinding and increased capacity. 2 dwg
