About 90-95% of a Portland cement is comprised of the four main cement minerals, which are C 3 S, C 2 S, C 3 A, and C 4 AF, with the remainder consisting of calcium sulphate, alkali sulphates, unreacted (free) CaO, MgO, and other minor constituents left over from the clinkering and grinding steps.The four cement minerals play very
Aug 30, 2010· Some of the CO 2 released during cement production comes from burning coal and other carbon-intensive fuels as a heat source in kilns that can run non-stop for over a year at a time. But portland cement is unique in that about half of its carbon emissions comes from calcining limestone, which emits CO 2 during the chemical reaction.
Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.
