Rod mills, how they function - Mine Engineer.Com. 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, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.

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. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

Hi All, we want to mill a relatively soft galena in limestone ore to prepare it for gravity concentration. Flotation is not possible at the site. The ore is easily liberated, so a grind down to about p80 of 1mm is ok, to feed it to spirals and shaking tables. We …
