Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N. N is related to mill diameter which decreases with larger diameters k a constant equal to π /4.

Recommended Rod Mill Bar Length - 911metallurgist

To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of tangling Increases rapidly. For rod mills larger than 3.8 meters (12.5 feet) in diameter rod availability and quality have to be considered.

Rod mills, how they function - Mine Engineer.Com

Rod 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.
