ABSTRACT An apparatus for uniformly feeding grinding balls to a grinding mill. The apparatus includes a ball storage hopper, a regulator and an inclined chute for conveying balls from the hopper to the regulator. The chute includes a panel for controlling the depth of the balls. The regulator includes a discharge drum having a plurality of compartments adapted to receive the balls, an electric motor for rotating the drum, and a means for retaining the balls in the drum. The drum is rotated at a predetermined speed and feeds the balls into a mill at a uniform rate which can be controlled to approximately match the attrition rate of the balls in the mill.
