Zusammenfassung:In designing cascading rotary dryers, it is important to size the flights correctly in order to ensure that they can adequately accommodate the contents of the drum. A set of equations has been derived to calculate the solids holdup on angular and extended-circular flights in such dryers. Three examples of the practical use of these equations are presented. These include estimation of the design holdup of the dryer, selection of the number of flights, and exploration of the flight cascade characteristics.
