Rod mills, how they function Mine Engineer.ComRod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

Reduction ratio ranges from 2 to 200.Typical reduction ratio = 8.The optimum reduction ratio can be determined from the following expression:R0R = 8 + 5L/D

Mill capacity is dependent on: 1. Mill Characteristics (length, diameter, rotation speed, lifters) 2. Feed Characteristics (work index) 3. Reduction Ratio Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N Nis related to mill diameter which decreases with larger diameters k a constant equal to /4.

Rod mill power is dependent on mill capacity and work index. Mill power increases with: 1. Increasing rod charge2. Increasing mill speed3. Increasing mill length. Rowland and Kjos (1980) provided an expression to quantify power draw at the pinion shaft per unit mass of rods: PM / MR = 1.752 D0.33 (6.3 5.4JR) CkW/t D = mill inside diameter (meters) JR= fraction of mill volume occupied by rods c= fraction of critical speed. The Rowland and Kjos equation indicates that power draw is a function of the fraction of the critical speed for the mill. cy mills are recommended to operate a peripheral speeds governed by the following relationship : Peripheral Speed= 108.8 D0.3meters/ min D = mill diameter in meters The cy expression is applicable for mill diameters between 1.52 to 4.1meters. Using peripheral speed, the rotational speed can be determined. Bond quantified the rod mill power draw as a function of the Work Index, capacity, and a series of correction factors: PM=
