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.

"Ball milling practice in the ore dressing industry is largely empirical. Although many investigators have worked on various of its phases, the present operating methods are mostly a matter of cut-and-try, with the result that the industry is not guided by its underlying principles. Consequently, practice varies extensively with regard to nearly all conditions of operations.
