To reduce the calcination temperature, and generates a portion of the melt Wuhan cement brick during calcination, often with a small amount of iron oxide material. Wherein the amount of raw materials but also to control the base and magnesium oxide, namely cement clinker MgO content should be less than 5% Wuhan cement tiles, total alkali content (Na2O + K2O) for the average cement should be less than 1.2%, on low base cement should be less than 0.6%. Cement cement raw meal components occur in the kiln is heated during a series of physical and chemical changes, such as evaporation of free water, water of crystallization off clay, calcium carbonate is decomposed into calcium oxide. White Portland cement is the most important varieties of white cement, iron and other non-ferrous metal oxide is a low content of limestone, clay, silica as the main raw material, calcination, quenched into cement clinker, adding an appropriate amount of gypsum (You can also add a small amount of white limestone instead of part of clinker), in a Portland cement containing stone (or wear metal) within mill liners and grinding media made of finely ground.
