Ball mill - Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

The cement mill
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

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 tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
Critical rotation speed for ball-milling - ScienceDirect
We modeled ball-mill as a quasi-two-dimensional object for simplicity, although real ball-mill is a 3-dimensional object. Here, quasi-two-dimension means that balls and jar were modeled as discs in our program except masses of the balls, which are calculated by taking the ball as a 3-dimensional object.
