A ball mill is a type of grinder used to grind or 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.

Objectives of size reduction Size reduction leads to increase of surface area. Pharmaceutical capsules, insufflations ( powders inhaled directly into the lungs), suppositories and ointments require particles size to be below 60 mm size. To increase the therapeutic effectiveness of certain drugs by reducing the particle size. Size reduction produces particles in narrow size range.

Ball milling induces selfsustaining reactions in many sufficiently exothermic powder mixtures. The process begins with an activation period, during which size reduction, mixing, and defect formation take place. The MSR (mechanically induced selfpropagating reaction) is ignited when the powder reaches a well defined critical state.
