calculations of ball mill for feed charge



Calculation of Top Grinding Media Size, 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).

Dear GKS You are correct in stating that main drive kw only increase when less grinding media charge and small sie of grinding media w.r.t. feed sie and feed rate.Mill Steel Charge Volume Calculation, We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or ....
