Chat OnlineRod Mill 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.
Chat OnlineThe cylinder of the rod mill rotates at certain speed and the grinding body rises to certain height and then is cast in the action of friction and centrifugal force to make materials be impacted and ground thus finishing the sand making process.
Chat OnlineCommon types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill.

Chat OnlineThe following cost advantages should be considered when evaluating rod mill grinding Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media.
