Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration.

Ball Mill Power Draw Calculation
CALCULATION OF THE POWER DRAW OF DRY. CALCULATION OF THE POWER DRAW OF DRY:In this paper a new approach for the calculation of the power draw of cement grinding ball mills is proposed For this purpose cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills ranging in diameters from 32 to 48 m The Rowland and Kjos (1980) provided an expression to quantify power draw at the pinion shaft per unit mass of rods: P↓M / M↓R = 1.752 D↑0.33 (6.3 – 5.4J↓R) Φ↓C kW/t. D = mill inside diameter (meters) J R = fraction of mill volume occupied by rods. Φ c = fraction of critical speed. The Rowland and Kjos equation indicates that power ...
