Ball Mill - Wikipedia

Ball mill - Wikipedia

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. a ball mill consists of a hollow cylindrical shell rotating about its axis. the axis of the shell may be either horizontal or at a small angle to the horizontal. it is partially filled with balls…
