Recent development on the uses of alternative fuels in cement
The basic chemistry of the cement manufacturing process begins with calcination, the decomposition of calcium carbonate (CaCO 3) at about 900 °C to leave calcium oxide (CaO, lime) and liberate gaseous carbon dioxide (CO 2).This is followed by the clinkering process in which the calcium oxide reacts at high temperature (typically …

Why Choose Dry Process From Manufacturing Cement Methods
Dry process cement production kiln is the typical kiln type during the end of the 18th century and the beginning of the 19th century. It is a big step for haft kiln. Because of its less than 1% water content dust raw materials, it reduces the most needed heat for evaporating water. So, it needs less time than wet process cement production.
