calcination rotary kiln

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.

(2) Thecalcination zoneis in themiddle of the rotary kiln. When the material enters the area, the fuel starts to burn under the condition of the blower’s combustion. Can release a lot of heat, so the temperature in the kiln will rise slowly, when the temperature reaches a certain range. At this point, temperature control is required.
