raw materials used in cement manufacturing introduction of limestone

Alternative Fuels in Cement Manufacturing | IntechOpen
Cement production involves the heating, calcining and sintering of blended and ground raw materials, typically limestone (CaCO 3) and other materials containing calcium, silicon oxides, aluminium and iron oxides to form clinker. Clinker production takes place at material temperatures of about 1450 °C in either rotary or shaft kilns.

The Cement Industry
The cement manufacturing process requires the use of raw materials such as limestone and additives to control the alumina, silica and iron content. In addition, a relatively high amount of energy is needed to convert the limestone to calciumoxide and to solidify and compress the material at 1,450°C.
