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 defines the capacity of the cement plant.

Cement Kilns: A Ready Made Waste to Energy Solution

In a typical cement kiln some 200 tonnes per hour of sintering material passes the burner(s). The ashes of the fuel used to heat the kiln drops into the glowing material and reacts with the hot minerals to become an integral part of the end-product - clinker. This clinker is then ground into cement.
