Rotary Kilns vs. Rotary Dryers: What's the Difference?
Rotary dryers are used for drawing moisture out of a material. As such, they typically operate at temperatures between 800º – 1400ºF. In contrast, rotary kilns are used to cause a chemical reaction or phase change, requiring them to operate at much higher temperatures, typically between 1000º – 3000ºF. Some moisture reduction may occur ...

How does a Rotary Kiln Work?
Rotary kilns can be either direct-fired, or indirect-fired (calciners). Direct-fired kilns use direct contact between the material and the process gas to cause the reaction, whereas indirect kilns rely on the heat emanating from the shell of the drum, which is externally heated to temperature. In the case of a direct-fired kiln, a refractory ...
