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 rotati

It is a solid-state mixing of powders, usually performed with ball mills, which enables intimate mixing of the constituents through repetitive plastic deformation. By applying discontinuously high strain rates, ball milling enables the reduction of particle size in addition to the effective mutual dispersion of the processed phases.
