− Ball grade − Race and ball material and microstructure, inclusion rating − Hardness of balls and races − Ball and ball path surface finish (roughness and waviness) − Method of manufacture grinding and honing of ball track (Some thin-section bearing manufacturers only hard turn the ball paths.) − Truth of Curvature − Contact angle
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.
