Optimization of a fully air-swept dry grinding cement raw meal ball
Average material height above the ball surface level (18 cm) and free height of the mill (2.27 m) were measured to be used in mill powder load (hold-up) calculation ahead of collecting the samples along the long axis of the mill at the crash-stop condition. Mill filling was calculated to be 32% using the mentioned geometrical measurements.

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).

Closed circuit ball mill – Basics revisited
The relative capacity model predictions (compared to the reference point of 250% circulating load and 50% classification efficiency) are presented in Fig. 7. It can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%.
