ROTARY KILN Some questions and answers of CEMENT
rotary kiln is. Let us explain these points briefly 1. Age and condition of the rotary kiln shell Old kilns shells have been exposed to creep for a long time and are more prone to develop fatigue cracks than newer shells. 2. Distance between tires The longer the rotary kiln shell span the less it will resist high temperatures without sagging.
