Diferrent between long dry rotary kiln and short rotary kiln

Aug 01, 2021 Rotary kiln and dryer are both high-temperature drying and calcining equipment in the production of building materials, but there are essential differences between the two. The detailed design of the structure is slightly different, the production process is different, and the use is also different

    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

    The main advantage of dry process kilns with pre-heaters is that the kiln gases pass over the raw mix thereby transferring their heat to the raw mix before it enters the kiln. Thus, the raw mix undergoes the final drying and partial calcination by using waste heat (4)
