    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.
