AMIT 135: Lesson 8 Rod Mills – Mining Mill Operator Training

Rod Mill Power Draft. Rod mill power is dependent on mill capacity and work index. Mill power increases with: Increasing rod charge; 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 .
