Jan 20, 2021 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.
The ball mill is a device for coarse, fine and ultra-fine size reduction or homogenization of ground material. It consists of a rotating grinding chamber in which the ground material is crushed by grinding media. The ball mills described here, in which balls are used to crush the ground material, are to be distinguished from stone mills.
