The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a) Mill Geometry and SpeedBond (1954) observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account. As well mills with different

This indicates that the rod mill reduction ratio is much larger than those at normal condition and ball mill reduction ratio is much smaller. » More detailed. standard number of reduction ratio of grinding mill. 150 where RRO = optimum reduction ratio for the mill size = 8 long and tedious and requires a standard set of grinding

The reduction ratio R in rod mills varies from 2 and 20 depending on the characteristics of the ore.The usual reduction ratio is about 8. According to Bond 4 the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio R RO can be written as

Ball mill . Cylindrical or conical shell slowly rotating about a horizontal axis. Half of its volume is filled with solid grinding balls Shell is made of steel lined with high carbon steel plate porcelain or silica rock. Size reduction is achieved by impact of the balls when they drop from near the top of the shell
