For stable kiln operation and to obtain uniform quality of clinker it is necessary to keep the variation in kiln feed in LSF 0.5, in SM 0.03 and in AM 0.03 measured as a standard deviation. A specific blending operation is therefore necessary to produce kiln feed of quality that is consistently uniform in chemical composition and also particle size distribution.
