This document discusses calculating raw meal to clinker ratios when accounting for kiln dust and bypass dust. It provides formulas to calculate the actual raw meal ratio based on kiln feed composition and loss on ignition values. With 4% bypass dust at 4.4% LOI, the ratio is calculated to be 1.726 rather than the assumed 1.65. Formulas are provided to accurately calculate ratios …

The lime saturation factor (LSF) is a ratio of CaO to other oxides, it is used to control the proportion of cement raw meal. In the operation of the cement kiln, the thermal system of the kiln can be affected by the fluctuation of LSF. The high saturation ratio will make the raw meal difficult to burn to clinker.
