Rotary Kilns
Ranging in diameter from 10 feet to more than 20 feet, they are often many hundreds of feet long. As the kiln rotates on its rollers, material is transported due to the kiln's low, gradual slope. Material entering the kiln at a few hundred degrees Celsius is heated to 1450°C as it nears the discharge where the burner pipe is located.

Everything You Need to Know on Rotary Kiln Refractory
As the rotary kiln rotates, that spot should read the same temperature for the entire circumference of the shell. For example, a temperature reading of 400º, 400º, 700º, 400º would likely indicate a failure in refractory. Left untreated, this could lead to severe damage to the rotary kiln shell. The image shown here illustrates a refractory ...

1. When processing fine materials, an indirect kiln avoids the risk of entrainment. When processing in a direct kiln, fine materials can become entrained in the process gas and carried out to the baghouse. An indirect kiln avoids this issue because there is minimal gas moving through the drum. 2. Less exhaust air treatment is required.
