Ball mill - Wikipedia

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. A ball mill consists of a hollow cylindrical shell rotating about

Where Dry Milling Makes Sense | Modern

By contrast, Alpha's high speed milling process allows just one of the coated carbide inserts to do the same job. Even though this insert is more expensive than one of the slab mill inserts, it's not five times as expensive. By using the one insert instead of five, the shop spends only about one-third of what it formerly would have spent on tooling for this cut. To realize such long life from
