what is rotating kiln
Rotating Kiln - an overview | ScienceDirect Topics
Rotating kilns were proposed as early as 1980 for use in solar particle heating applications [22]. The general principle is to feed particles into a rotating kiln/receiver with an aperture at one end of the receiver to allow incoming concentrated sunlight. The centrifugal force of the rotating receiver causes the particles to move along the ...

Gary L. Foutch, Arland H. Johannes, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 IV.Q Rotary Kilns 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.
