The design of flights in rotary dryers
Baker [9] also explained how to estimate the optimum number of flights in a rotary dryer to maximize the drum holdup and thus make the most effective use of the dryer volume. Kelly [10] extended his theory to the prediction of the ideal flight geometry that would provide the equal horizontal distribution (EHD) of solids.
