Circulating Load Calculation Formula. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier …

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.

high circulating load ratios, are desirable to make sure mill power is being applied to coarse, not to overgrinding fines. This is demonstrated in early work by E W Davis (shown in Figure1). Figure 1 demonstrates that a high circulating load ratio gives the best circuit production rate of new fines at a given energy input (Davis, 1925).
