Increasing mill speed; Increasing mill length. 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.
