    The grinding media in a Rod mill are long rods of particular material which grind the ore by tumbling within the mill. The grinding action is by line contact between the long rods. There is a very minimal slime production since rods tumble and spin in roughly parallel alignment and produce size reduction of coarse ores efficiently.
