  • Rod mills how they functionMine Engineer.Com

     · Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned grinding action is lost and more importantly rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length diameter and capacity of rod mills. The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65 rod
