Grinding Mill

To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables. The main disturbances in a grinding circuit are: 1. change in ore characteristics (ore feed rate, grindability, feed particle size distribution, mineral composition and mineral characteristics like abrasiveness, hardness), 2.

Grinding

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.
