Formation of c3s in cement kiln

Dec 11, 2012 The LSF controls the ratio of C3S to C2S in the clinker and this relationship therefore imposes limits on the C3S (50 - 65%) and C2S (5 - 20% ) content of the clinker. To promote good coating formation in the kiln burning zone, the liquid phase should be between about 23 - 28%

    Re: Conversion C2S to C3S . Dear Gks . Without the presence of liquid, the conversion of C2S and free lime to C3S at normal clinkering temperatures would be almost impossible. The most important clinker mineral, C3S (alite), requires the presence of liquid for its formation

    Alite formation Alite forms by the transition of some of the belite to alite and also directly from free lime and silica to alite. This occurs rapidly once the clinker temperature is above about 1400 C. Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali

    Therefore, when SM is too high, nodulization becomes weak and clinkerization reaction (C3S formation) rate slows down, kiln becomes dusty and difficult to operate. While as when SM is too low, more melt is formed in kiln, issues like thick kiln coating, kiln melting, snowman formation in cooler are more prone. Normal range of SM is 2.3-2.7

Lime and silica react readily to form C2S, but this C2S combines only slowly with residual lime to form C3S. The reaction; 2CaO SiO2 ———- 3CaO, SiO2
