For application to actual grinding systems, Eq. (8) is normally expressed in size-discrete form by defining average values of q, S and b for narrow, but finite size intervals. An analytical solution is available for this form for systems in which the breakage rates and breakage distributions are independent of time and of the size consist of the mill contents [5].
