Verheezen et al. proposed that grated screens reduce residence time in a conical screen mill due to the grates acting to channel material through the screen apertures, essentially improving the classifying efficiency of the mill screen. Lower residence times would result in fewer impacts, and therefore less breakage (Verheezen …
