Closed ball mill – cyclone circuits are industry standard and it is recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding. The individual effect of circulating load and classification efficiency is difficult to quantify in practice as
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.

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and …
circulating load ratio and ball mill circuit performance makes the optimisation objective seem nebulous to both plant metallurgist and designer. Some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of
