Rotary Dryer Design 101: Retention Time FEECO

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

Rotary dryer Wikipedia

The rotary dryer is a type of industrial dryer used to reduce or minimize the moisture content of the material it is handling by bringing it into contact with a heated gas. The dryer is made up of a rotating cylinder ("drum" or "shell"), a drive mechanism, and a support structure (commonly concrete posts or a steel frame). The cylinder is inclined slightly with the discharge end is lower than
