The Rotary Dryer . The rotary dryer consists basically of a cylindrical shell inclined at a small angle with respect to the horizontal position. To promote gas-solid contact, the dryer is equipped with lifting flights, placed parallel along the length of the shell, which lift solids and make them rain across the section of the dryer.
