The ball mill is a key piece of equipment for grinding crushed materials, and is widely used in production of powders such as cement, silicates, refractory material, and glass ceramics, as well as for ore dressing of both ferrous and nonferrous metals. Ball mills can grind wet or dry and can be continuous or batch type mills.
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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.
Traditional vertical mills and ball mills are often limited to a finished particle size of approximately 5 microns, which can be achieved only with careful attention to media size. Horizontal Mills. In contrast to vertical mills, horizontal mills have certain characteristics that are better suited to wet grinding. A horizontal mill is generally made up of a horizontal tubular grinding chamber, in the center of which is .
