When the grinding balls trajectory changes at constant critical speed, the tendency of the steel balls to hit the material to do the grinding work becomes less because most of the material to be hit by the ball were at the toe side of the mill (see the next figure) and that means for a low production output, unattainable quality targets, wear rates of grinding media due to ball .

The performance of the grinding circuit, from the initial stages of operation to the present, is discussed. The mill efficiency as measured by the Bond (Bond and Maxson, 1943) grindability data and the operating work index is objective was to produce a sand cyclone overflow containing not more than 6% 210 μm (+65 mesh). This has never been attained, even at low milling rates ...

It has been emphasized that, as the purpose of grinding is to produce fine particles, the mill design and scaleup work should be based mainly on the F * parameters. Moreover, it is not correct to regard the S * values to be independent of the mill design and operating variables as a general rule, especially for a fine analysis of the performance of the grinding systems.

· First, ball mill ball has higher hardness and higher HV/E value, in order to resist the grinding of hard abrasive grain. Second, ball mill ball has enough toughness (KI) to resist impact and crack propagation. Third, ball mill steel ball has good anti fatigue ability, in order to resist the effect of alternating stress and impact fatigue wear.
