BURNING 1.RAW GRINDING: Theraw materialsare very finely ground in order to produce therawmix. 2. BURNING : Therawmix is preheated before it goes into the kiln, which is heated by a flame that can be as hot as 2000 °C. Therawmix burns at 1500 °C producing clinker which, when it leaves the kiln, is rapidly cooled with air fans
