Factors Affecting Ball Mill Grinding Efficiency

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
