Intro to Size Reduction
the mill retain the coarse material for further processing while allowing properly sized material to pass through. 4., heavy material such as stone, glass or metal can exit the mill Hard via gravity. Lighter or low density materials such as wood and paper may require pneumatic suction for effective discharge. One size does not fit all

Circulating Load Calculation Formula
— 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).
