Cement Clinker Quality Control During Clinker Production
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 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.
