Calculation of Top Grinding Media Size Ball Sizing

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batchgrinding tests interpreted in the content of population balance models (Lo and Herbst 1986). The effect of ...

Grinding Media Charge Motion inside Mill

Grinding media management in ball mills. Grinding ball additions. Grinding balls should be added each shift. Mill performance is negatively impacted when the mill is not drawing power at targeted level. This results in coarser grind size or loss in throughput. The grinding balls can be added onto the mill feed conveyor when the mill is running.
