Everything You Need to Know on Rotary Kiln Refractory
This can be done by picking a spot on the rotary kiln shell, and holding a temperature gun in place. 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.

Reactions in the cement kiln
In a wet-process or preheater system without a pre-calciner, most of the calcination takes place in the rotary kiln within a moving mass of feed. This situation is not ideal for calcination because heat transfer has to take place through a large mass of material and CO 2 has to escape outwards as heat moves inwards.
