Rod mills are very similar to ball mills except they use long rods for grinding rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 14 to 16

For this coarser feed the 50 2010 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches the availability of a ball size for a particular feed size ensures breakage occurs at a faster rate the 10 mm ball size is unable to nip the

The length to diameter ratio of cylindrical mills range from 1 to 1 through 3 to 1 when the ld ratio is 2 to 1 or greater we refer to the mill as a tube mill trunnion overflow discharge a trunnion overflow mill has an open discharge end material flows through the trunnion as a result of the pulp gradient between the feed and discharge

The ratio of the trunnion thickness to trunnion diameter in a mill of 2134 m diameter is almost twice that of a mill of 58 m diameter ie a ratio td of 0116 to 0069 for the large mill however the design stress levels at the trunnionhead transition in the case of the large mill are almost 250 of those in the small mill
