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 of theget price

Rotary Dryer Sizing and Design SlideShare

Oct 21, 2015 The sizing and design of a rotary dryer is a complex process involving a number of factors and considerations. This presentation looks at the importance of custom rotary drum dryer design over a one-size-fits-all solution, and the many material characteristics and environmental factors that should be considered during the design process.get price

Rotary Dryer Design 101: Flight Design feeco

Lifting FlightsCreating The Optimal Material CurtainDetermining Flight Design Through TestingAdvancing FlightsConclusionFlights, 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 maximum drying efficiency.Depending on the manufacturer, flights are typically available in many forms, including straight, single bend, d...

Rotary Dryer Design 101: Retention Time feeco

Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results.. The retention time required for a given application is determined through balancing the necessary process parameters particle size distribution, air flow velocity, temperature, and more with the desired outcome; it can thenget price
