MATERIALS & APPLICATIONS

Product knowledge starts at the factory.

Our range covers cast grinding balls and cylpebs, forged grinding balls and rods, micro media, mill liners, crusher hammers and steel shot.

We work with buyers to define material grades, dimensions and inspection requirements. For mill liners and hammers, drawings and installation details form part of that discussion. For grinding media, mill conditions and size distribution guide the review.
