Exploring ball size distribution in coal grinding mills

May 01, 2014· The rate at which material is removed from a ball is proportional to the surface area of the ball at that moment in time, which can be written mathematically as: (1) − dV t dt∝ 4 π r t 2or dV t dt =− 4 k 1 π r t 2where V(t) represents the instantaneous volume of the ball, r(t) is the instantaneous radius of the ball, and k 1 is the constant of proportionality that takes into account the material from which the …
