raw materials (Iron ore, silica sand, gypsum and pozzolana are brought from nearby places. Limestone provides calcium oxide and some of the other oxides, while shale and the other materials (silica sand, iron ore) provide most of the silicon, aluminum and iron oxides required for the manufacturing of Portland cement.
Cement clinkers are formed by the heat processing of cement elements in a kiln. Limestone, clay, bauxite, and iron ore sand in specific proportions are heated in a rotating kiln at 2,770#176; Frenheit (1,400#176; Celsius) until they begin to form cinder lumps, which are also known as cement clinkers. These are usually ground with gypsum to produce the fine powder later mixed with liquid to produce
The Main Function Of Iron Ore In The Cement Is While Melting / Burning Of Raw Meal In Kiln Iron Ore Melts Itself And Liquidize The Material To Easy Pass From Kiln, Avoid Coating In The Kiln And It Supports Perfect Formation Of Clinker
Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills.
of raw materials. For example, the cement industry began to address climate change in the mid1990sone of the first industries to do so. Over the past 40 years, cement manufacturers have reduced the amount of energy required to produce a ton of cement by over 40 percent. The industry also has reduced its use of traditional fossil

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 ( in) to 25 millimetres ( 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.
After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects.
Cement Clinker Manufacturing Process with Reactions (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition. A pressure above atmospheric is required to vaporize the water from the slurry mixture of raw materials.
#0183;#32;The main component of cement is called clinker. Clinker consists of cinder lumps formed by heating limestone, bauxite, and iron ore sand to 2,770 o Frenheit. The production of clinker is very resource intensive. Producing one ton of clinker requires an energy input of between MJ and approximately tons of raw material.
