  • Rotary Dryer Design 101: Flight Design

    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 availabl在feeco上查看更多信息
