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).

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
