Cement clinker is produced by sintering the kiln feed at a temperature where 20~30% of the material melts to form a liquid flux. The final clinker formation reaction takes place by the solid reactants, C2S and CaO, dissolving in this flux, and the solid product, C3S, crystallising out of this flux. ...
