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.

Work Index Ball Mill, alluding to the grind ability list of Metals, is utilized to demonstrate the granulating trouble of the material. It is measured by a rule that to compute the work file ball plant in light of yield of every unrest of the factory after the material is ground to an adjusted state by the predetermined plan.
