As to the scale-up effect on the degree of size reduction, the trend predicted is confirmed with that observed in industrial cement mills in reasonable agreement. The equation of the grinding performance alone, however, does not evaluate the mill diameter and the length individually nor guarantee the powder filling to be a desired level.

Re: % of grinding media in ball mills for both chambers. The volumetric filling degree of modern finish mill is 27-30% for the first chamber and 24-27% for the second chamber.In your specific case first chamber may be loaded 114.76 MT- 127.52 MT and in second chamber you may load 197.91 MT - 222.65 MT.You should start media loading in both the chambers from lower value first and based on

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
