BALL CRUSHER WITH SPATIAL COMPENSATION OF IMBALANCE Russian patent published in 2016 - IPC B02C17/14 B02C17/24 

FIELD: disintegrators and devices for crushing.

SUBSTANCE: invention relates to ball mill drive with at least two holders of cups for grinding bodies. Ball mill (10) contains at least two sleeves (23) holders (13) on support plate (12). In each of holders shell with balls in horizontal position is pressed. Each of corresponding pair arranged holders comprise eccentric shafts (25) with equal eccentricities lying opposite to each other relative to axis of symmetry of sleeve. Eccentric shafts are driven parallel to plane of supporting plate (12). Each of eccentric shafts is connected to corresponding holder and rotates in bearing plate. Counterbalance (28) is balance weight for holder. Counterweight is connected to eccentric shaft and is pressed in holder. Counterweight is located under support plate on each of two eccentric shafts on opposite to holder connection and cam shaft section relative to longitudinal axis of shaft. Counterweights are located on sides opposite to each other relative to sleeve longitudinal axis. Using drive holders are performing circular movement in opposite phase.

EFFECT: invention improves structure to obtain accurately repeated motion mode of balls by ensuring certain and strictly directed circular motion of sleeves.
