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

Ordinary Portland cement (Types I and II) has a surface area between 3000 and 3500 cm 2 /g, while the surface area for rapid hardening Portland cement (Type III) ranges from 4000 to 4500 cm 2 /g. ASTM specifies a minimum surface area (as determined by the air permeability test, i.e. Blaine) of 2800 cm 2 /g for all types of Portland cement, except Type III for which a minimum surface area is
