Rotary Dryer Design 101: Retention Time
However, drum length and diameter have an interdependent relationship, so length can vary as diameter changes. Drum Slope Speed. Similarly, the speed of the drum (RPM), combined with the slope of the drum, can also be used to control retention time. All dryers are set on a slight decline so gravity can assist in moving material through the unit.

Drum-Drying - an overview ScienceDirect Topics
Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155°C.The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later.
