Rotary kilns are commonly employed to thermally process granular materials. While kiln rotation promotes particle mixing and heat transfer, it also leads to de-mixing through segregation of finer or denser particles, creating a “kidney” within the bed. Experience and experimental evidence indicate that rotation-induced mixing is insufficient to eliminate

IV.Q.1 Description. The rotary kiln is a long tube that is positioned at an angle near horizontal and is rotated. The angle and the rotation allow solid reactants to work their way down the tube. Speed and angle dictate the retention time in the kiln. Gas is passed through the tube countercurrent to the solid reactant.
