Mill (grinding) Wikipedia

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%.

Factors Affecting Ball Mill Grinding Efficiency

b) Feed Preparation With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material top-size to the ball mill. Significant inefficiencies are introduced as a result of the need for larger (and, as a result, fewer) grinding balls. Furthermore, as mill performance is related to the complete size distribution of the feed material, all
