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)

between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore hardness by size (12.5mm for RWI and 3.35mm for BWI), and/or grain size properties. The Bond rod mill work index is used to calculate the power requirement at intermediate size, i.e. from 12.5mm to about 1mm. The test has been

average, the rod and ball mill indices are essentially equal, but the ratio between the two can be quite variable. High RWI/ BWI ratios indicate competent ores with low ball mill hardness, while low ratios represent friable or coarse-grained ores.
