• ### 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(PDF) Circulating load calculation in grinding circuits,[Show full abstract] algorithm for circulating load calculation in mineral processing closed circuits, thus enabling the construction of mass, metallurgist and water reliable balances The High recirculating loads in Ball Mill Circuits - Grinding ,High circulating load is common in both reverse and direct ball mill grinding circuits Why? Because the ball mill closed circuit is the last stage before separation Cyclone overflow should be clean of coarse particles About the big pump, it’s one of the most important equipment when you are going to increase your capacity It’s always a limitation unless you have thought of it at the
