Under such occasions, indirect rotary drum dryers should be your choice. Rotary cylinder is enclosed partially by an insulated jacket. A series of burners heat at the bottom of jacket. Under this way, heat transfer is by radiation and conduction via cylinder. Only a small air flow is required to take away the water vapor. The entrainment of fines is minimal, therefore a simple cyclone dust ...

Direct and Indirect Rotary Dryers: What's the

Operation: direct-fired dryers use direct contact between the material and drying air to dry the material, with the potential of using internal lifting flights to maximize the heat transfer. Conversely, indirect dryers use heat emanating from the drum’s shell to dry material via radiation and conduction, avoiding direct contact between the material and drying air.
