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 consists of the mill base and the mill jar. There's one more important component to a ball mill, though: the media. The balls of heavy material which fall upon and crush the chemicals are called the milling media.
