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.

kiln feed rates must be set at 185 tonnes per hour to ensure the proper chemical reaction occurs. With the pneumatic actuator, the feed variation was +/- 5.5%, causing the process engineers to set a lower feed setpoint of 165 tonnes per hour to account for the "hunting" by the actuator.
