Mill (grinding) - Wikipedia

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%.

Mar 21, 2017 . To test their technique, the team threw the printed circuit boards of computer mice into the cryo-mill, which is made up of a container of argon gas and a steel ball. With the liquid nitrogen keeping the components at a constant, ultra-low temperature, the device is shaken so the steel ball grinds the e-waste.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow.
