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 batch grinding tests interpreted in the content of population balance models Lo and Herbst 1986 .
