The effect of grinding conditions on the response of an ore can be studied by varying one condition at a time and deducing information from the data. Man indicates that mill speed affects energy consumption and throughput. The ball size influence mill throughput, power consumption and progeny size,.

The hardness, toughness, dissociation and structural defects of the raw ore determine the difficulty of grinding. If the grinding degree is small, the ore is easy to grind, and the smaller the wear of mill liner and steel ball is, the smaller the energy consumption is; on the contrary, the opposite is true.

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (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 ...
