Figure 8.2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is ...

The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained by restricting ore feed size to 3/4".

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
