Direct dryers are used more frequently than their indirect counterparts, because of the efficiency they offer. And while direct fired rotary dryers are most often the selected drying method, indirect rotary dryers are a valuable alternative for specific processing needs.
Material of Construction: direct dryers are primarily constructed of carbon steel, and indirect dryers are primarily constructed using a high temperature alloy. Industrial Use / Applications: Direct-fired rotary dryers are used more often than their indirect-fired counterparts, and are commonly seen in the agriculture and mining industries.
Rotary tube furnace dryers transport the feed from the inlet to the discharge of the dryer by the rotation of the drum and the angle of inclination of the drum. The drum tube passes through a furnace that is heated either by electrical elements or by gas burners. This energy heats the tube which is in direct contact with the feed internally.

The Indirect Heat Dryer is a unique piece of equipment that is designed to provide a method to dry, calcine, or otherwise process materials in a controlled (oxygen lean) atmosphere. The selection of an indirect heat dryer is not made lightly as they are both expensive and inefficient.
Rotary Dryer. The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, usually
Or, in the case of an indirect dryer, the heated furnace exhaust air can be recirculated into the combustion process since the air does not come into ROTARY DRYER HANDBOOK 13 contact with any of the material being dried.Recycling heated air from a direct-fired dryer is less desirable, because the exhaust air leaving the dryer is contaminated with dust particles that would need to be filtered
