Cement kiln - Wikipedia. Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually …
Dry process method means manufacturing raw materials into raw materials powder, whose water content is generally less than 1%. So, the dry process can `reduces heat loss needed by heating and autoclaving water. But the dry process has its own flaw that is the bad fluidity of materials grain in a kiln. It will cause an uneven mix.
