is a rod mill an open circuit

Rod Mill - an overview ScienceDirect Topics

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.

2016-1-1  For a rod mill–ball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less (e.g. from a closed circuit crusher) do not apply a rod mill efficiency factor.
