You need a two-stage solution, first stage open-circuit mill and then second stage closed-circuit mill. First stage, will be broken into two parts as well, you use a Bond rod mill work index for the coarse component of the ore (+2.1 mm) and the Bond ball mill work index for the fine component (-2.1 mm).
Identified in terms of circulating load, f, andpS will be: and Eq. 9 was solved for abritrary values of ps and the correspon- ding values of RVo were estimated. Then a scale for P, was established at the left hand side of the chart opposite to RVo scale but shifted upward by of circulating load scale. This

The circulating load in ball milling process is a crucial factor to consider for optimal operation and efficiency. By understanding how to use the circulating load effectively, you can enhance the performance of your ball mill. One way to utilize the circulating load is by adjusting the rotational speed of the mill.
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).
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.

How Much Circulating Load. In designing a closed-circuit crushing stage, the question of how much circulating load should be carried is a very important one. It not only has a direct bearing upon the capacity of the stage; it determines the amount of screening surface, and the elevating capacity necessary to handle the load in the circuit.

A closed circuit operation could be assumed with recycling of about 50% of the HPGR discharge to be mixed with fresh feed, the other 50% being the final product. A circulating load of approximately (HPGR recycle in proportion to fresh feed) would thus be achieved, approximately representing a two-pass operation.
