A high-temperature kiln, often fuelled by coal, heats the raw materials of calcium carbonate (generally in the form of limestone), silica, iron oxide and alumina to a partial melt at 1450°C, transforming them chemically and physically into a substance known as clinker. This grey pebble-like material comprises special compounds that give cement its binding properties. Clinker is mixed with gypsum

It will help to desulfurize higher Sulfur or Sulfur dioxides (SO₂). So it is most important to know the amount of Calcium Oxides (CaO) present in the lime stone that we are using. Lower the Calcium Oxides (CaO) will increases the Lime stone consumption.
