If the circulating load decreases, the cyclone feed density decreases and a finer product size is produced. The circuit is self-compensating and thereby prevents rapid changes in circulating load. In essence, the circuit will reach an equilibrium product for a given ore type, grinding power and feed rate.

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 ratios and circulating load tonnage on tons/day or tons/hour. This is %Solids/Densities ...

If the cyclone keeps returning ore to the ball mill, the total volume of ore will be increasing in the grinding circuit, as is the density of the slurry. The recirculating ore is also called circulating load. If the grinding process becomes less efficient, the circuit load will climb until its volume is greater than can be handled.
