Get PriceDec 14 2018 Also known as the firing zone the burning zone is at the lower end of the rotary kiln where the cement components are heated to about 1300 C to 1450 C forming clinker Accurate temperature measurements are critical for product quality environmental performance and kiln lifetime
Get PriceDuring the operation of the rotary kiln flames can reach temperatures as high as 1900 C 3452 F in order to heat raw materials to roughly 1500 C 2732 F As a result these materials become partially molten and undergo a series of physical and chemical reactions to
Get PriceHigher SO 2 emissions by rotary kiln systems in the cement industry are often attributable to the sulfides contained in the raw material which become oxidised to form SO 2 at the temperatures between 370 C and 420 C prevailing in the kiln preheater
Get PriceIt may consist of refractory bricks or cast refractory concrete or may be absent in zones of the kiln that are below approximately 250 C The refractory selected depends upon the temperature inside the kiln and the chemical nature of the material being processed
