    2021-12-6 · Mineral grinding is a simple process and not much technical complexity involved. Therefore, motivated person with good communication skill to sell end products to The main raw materials are in the form of mineral lumps obtained from respective mines. For the purpose of this profile, bauxite is taken as raw material and this canGrinding Mineral Technologies Group,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.
