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%.

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.

When rotating machinery is inoperative, this affects its associated systems and industrial complexes. In 1985, the Electric Power Research Institute estimated that 40% of stoppages at fossil-fuel stations in North America were due to rotating machinery problems, and in France the loss due to disruptions in 900-MW turboalternators was equivalent to the energy produced by a 750-MW machine.
