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,Quantifying Grinding Efficiency  Grinding,,EF1 Dry grinding  for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding. EF2  Open Circuit Grinding  when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.How to Measure Grinding Efficiency,The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills.
