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.
