The cement clinker grinding plant or cement grinding station acts as an individual production line while in the final period from the cement production course of action. within the finished product time period the cement clinker is ground by including reasonable mixing products and after that forms the completed cement.
Then the raw mix the ground stone passes through the firing stage in furnaces that reach 2000 C and is subjected temperatures in excess of 1450 C for 10 seconds. This produces an artificial rock called clinker which when mixed with additives such as gypsum and other materials is ground grinding mill to produce different types of cement.
Cement is produced when you mix clinker with other additives such as gypsum. Concrete is produced by mixing cement with aggregate and allowing that to harden or cure. The limestone and clay require a tremendous amount of energy to heat them in the process.
unit of material produced was obtained from the InEnergy Report produced for the Cement and Concrete Institute Camp;CI of South Africa. The study determined that on average 39.7 Mt of raw materials are consumed per year and 4.92 x 109 kg CO 2-e emissions are emitted per year to produce cement and aggregates for concrete production in South Africa.

Clinker is a nodular material produced in the kilning stage during the production of cement and is cheap as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400 C-1500 C in the rotary kiln. .
