The Circulation Factor is the percentage of Usable Area that makes up the Circulation Area. This distinction is demonstrated below: COMMON MISCONCEPTION. CIRCULATION AREA = ~ 17,000 NSF Legend The proportion of open to enclosed spaces is the best gauge for determining a Circulation Multiplier.Circulating Load Calculation Formula,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
