The simple input method (A1) is in principle based on the determination of the loss on ignition of raw meal ( LOI RM, uncalcined). The loss on ignition of the kiln feed (LOI kiln feed) can be used instead of LOI RM, as long as the dust return is not significantly calcined (degree of calcination: d<5%) and contributes with less than 20% to the ...

Raw Meal Homogenizing The raw meal homogenization is a key factor for stable clinker calcination 4 Read more calculating … Production Process The major oxide in the process is CaO is subjected to react with other oxides as silica, alumina and iron oxide presented in the Raw Meal, at elevated temperatures forming the clinker …

Lime Saturation Factor (LSF) is the ratio of the actual amount of lime in raw meal/clinker to the theoretical lime required by the major oxides (SiO 2, Al 2 O 3 and Fe 2 O 3) in the raw mix or clinker.It is practically impossible to complete the reaction to , in a reactor like rotary kiln, therefore there will always be some unreacted lime (CaO f) known as free lime.
