Selection and breakage functions are lumped into a steady-state mill matrix. This steady-state mill matrix is multiplied (on the right side) by the feed matrix which describes the particle size distribution entering the mill. This multiplication yields the mill product matrix which describes the size distribution of the particles exiting the mill.

Analysis of mill capacity using a theoretically derived selection
198961· The present study assumes that the grinding mechanism is dominated by impacts of balls falling onto the bed surface. The derived selection function is then used to estimate the mill capacity for ball mills, as a function of operational parameters such as powder and ball fillings. The results are in reasonable agreement with experimental data.
