Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (i.e., increased feed water) at least down to the range of 45 …

Rod Mills are similar with the Ball Mills xcept 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.

FIG 1 - Mount Isa Copper concentrator grinding circuit, 1973 - 1991. Between 1991 and 1996 the grinding circuit was operated on the principle of maximum throughput to minimise unit costs.

 — There is no reported evidence that feed size has any effect on rod mill power draw. Because the solids in the rod mill are known to appreciably expand the mill charge (as observed in the charge level before and after grinding out the mill), there would likely be a tendency for power draw to be lower with coarser feeds and at higher feed rates.

Essa RM Series Laboratory Rod Mills are recognised for their efficiency, uniform granularity and high quality sample achieved when milling and grinding. Use them to mill soft, hard, brittle and fibrous materials, either in a wet or dry state. With slightly larger barrel volumes than the Essa ball mill series, rod mills are ideal for larger and ...

 — The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power. When calculating rod mill power for a rod mill-ball mill circuit, do not allow for …

Sepro Tyre Drive Grinding Mills are a reliable solution for small and medium capacity grinding applications and are suitable for ball, rod and pebble charges. Sepro Grinding Mills come complete with a Variable Frequency Drive (VFD) package which allows you to fine tune the operation of the grinding mill based on the charge and mining application.

Rod mills are very similar to ball mills except for the use of steel rods as grinding media. In the rod mill, steel rods grind the ore by rolling and rotating. The feeding of rod mill is 50 mm, and its output particle size is -4 to 35 mesh. Rod mill produced by FTM Machinery Application fields of rod mill Applications of rod mill

 — The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%. It has been found that as grinding rods ...
