How Do Indirect Heat Rotary Dryers Work?

How the Indirect Heat Dryer Works. Materials are fed into a rotary drum that is encased in a stationary refractory lined furnace. This furnace casing has a series of burners mounted down the length of one side firing into the furnace chamber. As the material progresses down the length of the unit, it is subjected to different temperatures in

Indirect Heat Dryers Looking for Indirect Heat Dryers

Indirect Heat Dryers. Indirect heat dryers are unique pieces of equipment that are 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.

Indirect Drying vs. Direct Drying FEECO International Inc.

Indirect dryers rely on the heat emanating from the drum’s shell to dry the material via conduction and radiation. Subsequently, indirect dryers would not benefit from the addition of lifting flights, since there is no process gas moving through the drum. Furthermore, because the furnace exhaust is kept separate from the process gas, indirect
