Circulating Load Calculation Formula - 911 MetallurgistSep 10, 2017 . Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and.Determining the Bond Efficiency of industrial grinding circuitsThis is returned to the mill and ground for the number of revolutions calculated to give a circulat- ing load of . The grinding cycles are continued until the grams of undersize produced per revolution reach equi- librium, and/or reverse direction (change from increase to decrease or vice versa). Then the final circulating.
