the kiln inlet will support the kiln drive system. The other piers will have large bearings in place on either side of the kiln that engage with a smooth "tire" around the circum-ference supporting the kiln. The drive system is installed at the same pitch angle as the kiln itself for proper alignment. Rotary kilns for the cement industry
Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.
