Designed to provide an efficient means for continuously processing granular materials and powders at high temperatures in oxidizing, inert or reducing environments, rotary calciner consists of a cylindrical rotating tube housed in a refractory-lined gas or electric furnace, positively sealed to prevent air infiltration.
Because the bed of material is constantly being turned over, solids-to-gas contact is optimized, minimizing process gas consumption and reducing the size of off-gas treatment systems. Product quality is optimized by a design that establishes and maintains the temperature profiles required of the process. The internal-flight design promotes a gentle tumbling action and provides uniform exposure and efficient heat transfer.
