Let us apply these ideas to the derivation of an equation for the rate of grinding in a mill. It follows that if, as appears reasonable, the change of specific surface S cm²/cm³, within a mill depends upon the diameter of the mill, upon the ball diameter and upon the mean diameter of the particle, D, d and b respectively, upon the density of the balls and the pulp, q and σ …
