Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.
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.
