Recommended Rod Mill Bar Length
2015-10-1 Table II gives rod length to mill diameter ratios for the larger diameter rod mills. 6.8 meters (20 feet) Is a practical limit on the length of good quality rods (that is rods that will stay straight in the mill and will break in to pieces that will discharge from the mill when worn). This length is a function of rod

Rod mills, how they function - Mine Engineer.Com
2012-11-26 This in turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill

Rod Mill - an overview ScienceDirect Topics
The rod mill. In the rod mill, high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls. This mill gives a very uniform fine product and power consumption is low, although it is not suitable for very tough materials and

The buckling failure modes of rods with large length
Aluminum rods of length-to-diameter ratios ranging from 13 to 72 were fired from a powder gun and impacted against a rigid target plate. High-speed photography with framing rates of 13 000 to 500 000 frames per second and flash X-rays were used to record the transient response of the projectile and the resulting deformation.

AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill ...
A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.
