effect of grinding media on ball mioll gridability

Ball mill media optimization through functional performance

Numerous torque mill tests, in addition to the growing plant data base compiled to date, show that media charging near the size that provides highest ball mill grinding efficiency provides a degree of robustness with changing ore grindability. It is rare that the media is incapable of breaking the largest particles as they become tougher.
