materials containing calcium, silicon, aluminum and iron oxides are
crushed and milled into a raw meal. This raw meal is blended and then
heated in the pre-heating system to start the dissociation of calcium
carbonate to oxide. The meal goes further into the kiln for heating and
reaction between calcium oxide and other elements to form calcium
silicates and aluminates at t a temperature up to 1450 centidegree: so
called clinker burning. The cyclone system is attached to the rotary
kiln by a riser duct. Secondary fuel is fed to the riser duct, the main
fuel mixture, coal/petcock, fires the kiln. Reaction products leave the
kiln as a nodular material called clinker. The clinker will be
interground with gypsum and other materials to cement.
