Hello;

I want to know what is the exact meaning of upper transition, lower transition, burning zones in the rotary kiln??? everybody here give me different answer? I need help please!

Thank you very much

 

The burning zone of a cement kiln is the hottest part of the kiln, under the flame where the final combination into the clinker minerals takes place. Behind that burning zone is the upper transition zone where the temperatures is rising to that in the burning zone. In front of that burning zone where the clinker has been formed and is about to enter the cooler is the lower transition zone.

hey all,

Is there easier way to determine these zones so when i enter the kiln i will be able to know in which zone i am standing?

best regard

You might be able to tell from the coating on the lining. There should be coating in the burning zone, but the upper transition zone is often withut coating.
