How to solve the red rotary kiln without stopping

How to solve the red rotary kiln without stopping

3. The rotary kiln is a red kiln. At this time, it can be observed by infrared scanning temperature curve and its position can be accurately determined, and the concrete level of the red kiln still needs to be observed and implemented on the spot. Generally speaking, the infrared temperature and position of kiln shell should be controlled below 350 C when the peak value of curve is more than 350 C.

As the meal passes through the burning zone, it reaches clinkering temperatures of about 1400 C - 1500 C. Nodules form as the burning zone is approached. When the clinker has passed the burning zone, it starts to cool, slowly at first, then much more quickly as it passes over the nose ring at the end of the kiln and drops out into the cooler.
