The new dry-process cement production line technology was developed in the 1950s. So far, in Japan, Germany and other developed countries, the production rate of new dry-process cement clinker with suspension preheating and pre-decomposition as the core accounted for 95%. A suspension preheating and precalcining kiln was commissioned in 1976.
7. MANUFACTURING Of PORTLAND CEMENT Portland cement is made by heating raw materials rich in oxides of silicon, calcium, aluminum and iron to temperatures of around 1200 - 1400o C. The chemical reactions that occur within the partially molten mass result from the formation of the four main cement materials. Tricalcium silicate (CaO)3•SiO2 C3S 45 …
