Typically this type of mill can deliver a product with a fineness of less than mm. Testing of material is needed before hand to determine the suitability of the ore for processing in an autogenous mill. The rod mill (Fig 1) is a tumbling mill which is having a large percentage of its volume (30 % to 40 %) loaded with steel rods.
The mill is filled with a suitable grinding media and the area between each disc is essentially an individual grinding chamber. As a result the mill is effectively 8 grinding chambers in series. ...
