Breakage mechanisms and mill performance in ultrafine grinding

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]

Modeling and Simulation of Ultrafine Grinding of
