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).

Get PriceDepending on the nature of the feed and the circulating load, at times the discharge of the ball mill may get choked. This is indicated by the continued reduction in the discharge rate from the mill. In such case often there is a tendency to increase the water flow rate inside the ball mill to flush out the choking amterial. In many cases it
