dryer to the other In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for vaporization of the water To promote gas-solid contact, most direct heat dryers have flights (see Figure 1), placed parallel along the length of the shell, which lift solids and make them rain across the dryer section The
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 then .
