Calculation of Top Grinding Media Size  Ball Sizing
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 sizecan 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 effect of ...

The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters ...
