## Ball Mill Circulating Load - Mineral Processing & Metallurgy

Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios Pulp samples collected around the ball mill

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 known over an 8-hour shift
