Secondary rock milling was expanded toward the particle sizes of primary milling while still utilizing the practices of secondary milling. The closed circuit test mill was installed in an operating plant in parallel with existing conventional rod mill-ball mill circuits. Three stages of open circuit crushing were used to prepare rod mill feed.

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.
