Good figures for rod and bar mills are 90 to 93 for structural mills the good mill utilization figures are 75 to 78 if a mill rolls 80 of the calendar year that is 365 x 24 x 080 7008 hours if the mill rolls 800000 tons per year it runs at an average production rate of 11416 tonshour
Rod mills are very similar to ball mills except 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 14 to 16
