Rotary Dryer Design 101: Flight Design

Flights, or material lifters, are fin-like structures affixed to the interior of the rotating drum. As shown in the diagram below, these flights pick up material from the bed and shower it through the stream of hot gas as the drum rotates, creating a “curtain” of material. This maximizes the heat transfer between the process gas and the material to promote maximuCreating The Optimal Material Curtain

THE DESIGN OF FLIGHTS IN CASCADING ROTARY DRYERS: Drying

Jun 16, 2010· 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.
