    • Rotary Dryer Design 101: Retention Time

      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 ...


      Literature on rotary dryers is primarily focused on design methodology and on fundamental parameters needed to understand the physical phenomena involved in this equipment. In this paper we consider an alternative point of view which represents a contribution to the analysis of the performance of existing rotary dryers.

    • Rotary Dryer Design 101: Flight Design

      Rotary dryers have been a part of the thermal processing industry for over a century, and have earned their reputation as the industrial drying workhorse. These robust industrial drying systems have become a staple in just about every industry requiring bulk solids to be dried, including agriculture, chemical, and mineral processing – among others.

      rotary kiln. This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln.
