uses of flights in rotary dryer

Nov 26, 2001 Rotary dryers for particulate solids commonly use flights along the length of the shell to lift solids and make them rain across the dryer section. These flights are critical to dryer performance. Previous models for the prediction of the solids holdup in rotary drums have assumed that the angle of the solids level in a flight is independent of

    Direct heat dryers, where the heat transfer occurs by convection of hot air or gas inside a rotary cylinder, are the most common and used thermal dryers. Hot air or gas flows through the cylinder and then transfers to the product, warming it and evaporating the water, therefore temperature of heating media inside the dryer is the mean parameter

    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
