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 ...

Mil Relation Formula: The core of rifle scope range estimation is a math problem referred to as the "Mil Relation Formula". This takes the height of the target in inches, multiplies it by a constant and then divides by the number of mils read in the scope. The basic formula looks like this: The 27.77 is a "constant".

Note that the above equation (3), was derived to empirically relate power consumption over a wide range of mill sizes, on various slurries, as well as over a fairly broad range of mill speed and load levels, all combined into a single expression. Effects such as slurry density, media size, liner condition, and trunnion opening size are ignored.
