Typically R 8. Rod Mill Charge Typically 45 of internal volume; 35 – 65 range. Bed porosity typically 40. Height of bed measured in the same way as ball mills. Bulk density of rods 6.25 tonsm3. In wet grinding the solids concentration 1s typically 60 – 75 by mass. A rod in situ and a cutaway of a rod mill interior.
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.

small size grinding ball mill for ore lab testing. To that of the ball mill test as follows it is common to observe a difference 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 Mm for rwi and Mm for bwi andor grain size properties the bond rod mill work index is used
Rod Mills How Do They Work 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 1.4 to 1.6.
