Rod Mills, How Do They Work? - 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 Critical Speed is used for the determination of ball ...
