How to Calculate Grinding Mill Operating Efficiency

Efficiency = Wio/Wi x 100. When (Wio/Wi)x100 is less than 100 this indicates the circuit, based upon this comparison, is operating efficiently. When it is greater than 100 this indicates the circuit is operating inefficiently. A large difference, either low or high, could indicate that the two work indicies are not on the same basis.
