Cast Grinding Steel BallsThe best way to compare primary versus secondary grinding conditions is to review MBWT data from primary and secondary appliions for the same mill. This comparison is presented in Table IV. The Wear Speeds in secondary grinding are found to be 25 – 40% lower than those seen in primary milling when grinding the same, but finer, ore.

Influence of type of lining in highpressure grinding ...roll). Two main types of the rolls linings are applied in hard ore grinding: studded and hexagonal. The studded surface consists in metal ring with the pins (studs) embedded in regular distances from each other. The head of each pin protrudes above the surface of the lining, and an autogenous wear layer can be formed by ore packing itself between the studs on the roll. This layer provides a ...
