Design Of A Rotary Kiln For Cement Production
Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
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 clinker - Wikipedia
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
Cement Production: From Clinker Production to …
Perfectly mixed, accurately fed without pulsation, and precisely weighed 3. Clinker production. Schenck Process’s MULTICOR® K mass-flow feeding system plays the main role in the second cement production stage. It is used after the raw meal has been burnt in rotary kilns at temperatures of over 1,000 °C to produce clinker.
