Circulating Load Calculation Formula
Feb 21, 2015 Cytec Handbook. 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 (Fig. 70).

Circulation Load vs Fresh Feed with Example Minerallurgy
Feb 26, 2021 “The circulating load ratio is necessary to determine the capacity of the ball mill initially. Once the ball mill is installed, you cannot change its capacity” The underflow is circulated into the ball mill as shown in the figure “The underflow is not a waste; it is further sent to the ball mill operation for further recovery of the particlecontaining mineral” From the above example, we can determine the …
