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 tuling balls. Ball mills normally operate with an approximate ball charge of 30%.
