EFFECT OF BALL SIZE DISTRIBUTION ON MILLING

EFFECT OF BALL SIZE DISTRIBUTION ON MILLING

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%. Mar 26, 2021 Therefore, when it is required to improve the ball mill grinding efficiency, within a certain range, reducing the feed size has a significant effect, but the feed size cannot be too fine. It is necessary to comprehensively consider the nature of the ore, grinding efficiency, separating conditions, grinding technology and economic factors to ...
