    Best Practices in Rotary Dryer Design

    A common practice in rotary dryer design is to oversize the drum diameter to accommodate a more aggressive air volume. While this approach isn’t necessarily wrong, it is not as efficient. The larger diameter drum helps to combat the potential for material to become entrained in the air flow and carried out through the exhaust gas system

    In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat re- quired for the vaporization of the water. To promote gas–solid contact, most direct heat dryers have flights, placed parallel along the length of the shell, which lift solids and make them rain across the sec- tion of the dryer (Revol et al., 2001)

    Aug 05, 2021 The rotary dryer is a dryer type used in the industry to reduce the water content in the materials. Rotation facilitates the exposure of the material to heat sources that increase its temperature, which helps to eliminate or reduce its water content. Rotary dryers are made up of a metal cylinder or drum that rotates and has a slight inclination
