Rotary Dryer Design & Working Principle

For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to the material to be dried, Rotary Dryers

FLIGHT DESIGN I N ROTARY DRYERS: Drying Technology: Vol 10

Jun 16, 2010· It is reasoned that the EHD flights, which have an equal distribution of particles across the horizontal diameter of the rotary drum dryer, give the optimum distribution in the context of the heat and mass transfer operations of the rotary drying process. An industrial design which approximates the optimum flight design is suggested.

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.
