### Circulating Load Calculation Formula

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 Based Circulating Load Calculation Method obtained from the pulp/slurry …

### Ball Mill Circulating Load - Mineral Processing & Metallurgy

As the circulating load increases to higher levels, it is also not uncommon for the pump or the cyclone to become the capacity bottleneck due to volume constraints. These volume constraints are not always readily apparent, leading to the assumption that the increased circulating load has limited the ball mill capacity. Therefore, changes to the pump and cyclone may be required to handle the higher …
