Ball Millan overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1.5 times the shell diameter Figure 8.11 .The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.

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 .
