The mill's SAG/ball/flotation circuit was initially designed for 35,000 mt/d. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mt/d. However, the increased circulating load led to overloading of the original 12 x 28-ft …

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).
