Open-Circuit vs Closed-Circuit Grinding: Key Differences and …
Closed-circuit grinding has high-efficiency crushing rate, so the product quality obtained is higher, and at the same time, the output of closed-circuit production is larger. But the main disadvantage is that the closed-circuit production process is more complicated and the investment cost is relatively larger.

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).
