What is the Difference Between a Rotary Dryer and a Rotary Kiln

Rotary dryers and rotary kilns share similar thermal processing functions, but each is intended for very different industrial applications. Rotary dryers operate at inlet temperatures between 600 and 1400ºF, and are predominately used to draw moisture out of a material. Rotary kilns, on the other Continue reading →
