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.
