Overall,the cement manufacturing is a 6 stages, linear process, starts with adding limestone and clay as raw materials into a crusher and ends with cement being packed into bags. The concrete production is a 2 stages process, starts with adding cement, water, sand and gravel into a concrete mixer and ending with concrete production.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium silies.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 manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
