Grinding Mills and Their Types – IspatGuru

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 rods are placed axially in the mill and are loose and free to move within the mill. The internal lining of the drum has a series of lifters which raise the rods and drop them at a predetermined point.

Charge Dynamics in Tumbling Mills

The most common types of tumbling mills are the rod-, ball- and autogenous mills. Depending on the type of ore, there are different charge media to be used. In rod and ball mills, the different charge media are usually made of steel and added to the mill. In autogenous mills, the ore itself is used as charge medium.
