  • Consider a hammer mill (or a section of a hammer mill) that is fully mixed by the rotating action and is receiving a known feed size distribution f i at a known mass flow rate F (kg/s). It is expected that the rotating action will cause size classification so that larger particles will be preferentially held in the mill as compared to finer particles (exit size classification).
