  • Effect of Milling Environment on the Breakage Rates in Dry

    Abstract In ball milling the rates of breakage vary primarily with the size distribution of powder in the mill. Using an approximate solution to the batch-grinding equation the acceleration and deceleration of breakage rates of all individual size classes are determined when the grinding environment is varied.

    Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30 .
