Calculation of Top Grinding Media Size -Ball Sizing

2015-10-14  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). The

Ball Mills - an 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.

The hardness of grinding media ball - how to choose

Grinding media Ball is one of the essential parts of ball mill. The quality of grinding media ball affects not only the productivity of the ball mill, but also the consumption of ball, and then affects the cost of grinding medium. The pursuit of high hardness and low single consumption is not right.
