Mar 15, 2005 values of mill filling. Grinding rates were determined for particular size grades. Changes in the size distribution of ground material in time were analysed and the effect of ball size, degree of filling the mill with feed and the number of grinding balls on the process rate was reported. This rate varies.

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
