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

Apr 27, 2007  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.

Flights (rotary dryer) — Wikipedia Republished // WIKI 2

Flights, also commonly referred to as "material lifters" or "shovelling plates" are used in rotary dryers and rotary coolers to shower material through the process gas stream. Fixed to the interior of the rotary drum, these fin-like structures scoop material up from the material bed at the bottom of the drum and shower it through the gas stream as the drum rotates. This showering creates a ...
