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, allowing to calculate corresponding to circulating load ...

So do a material balance around the circuit, figure out the mass flow rate of solids in the cyclone underflow and divide that by the mass flow of solids in the circuit feed. You can then get more complicated if you want, and track the circulating load of some sub-fraction, the water, radioactive tracers or .
