In most instances, however, damage can be avoided if the kiln is shut down for lining replacement as soon as the shell starts to show a large red spot. This becomes all the more important since replacement of the refractory lining in the burning zone of a cement rotary kiln makes a huge adverse impact on the operating budget and the production schedules.

If the refractory lining of the rotary kiln were to become damaged or compromised in any way, then a hot spot would appear on the outer shell of the kiln. If left unidentified, the kiln can warp, resulting in extensive damage and extended down time. Scanning or

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

1/7/2012· The pelletising of iron ore as a burden material for blast furnaces has been used commercially since the early 1950s. Two main processes are used today during such production: the travelling grate and the grate-kiln process. 1 In the grate-kiln process, which is studied here, the grate is a pre-heater and the kiln is a rotating furnace lined with refractory bricks.

This transmission used for rotary kiln can better solve the shortcomings of traditional transmission mode and the impact of the bending deformation of the rotary kiln on the drive device. Since the length-diameter ratio of the rotary is large and the rotary kiln is running in the high temperature, the cylinder of the rotary kiln will have bending deformation with different degrees.
