Key Factors in Rotary Kiln Shell Design
The length of the calcining zone is about 50% of the total length of the kiln body, which also makes the high-temperature area of the kiln body long. And the length of the kiln skin used to protect the kiln shell from high temperature is 5.5 ~ 6D. In the actual operation, the surface temperature of the kiln shell after the kiln skin is about 400 ℃.
