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. A ball mill consists of a hollow

RATE OF CERAMIC BODY GRINDING IN A BALL MILL
Mar 15, 2005 A simple construction of the mill is not in keeping with process efficiency. Low efficiency of the grinding process makes technologists look for such a composition of balls and mill filling for which the mean particle size is reduced the fastest. This enables a more economical use of the mill working time.
