composition of raw material for making clinker

three processes in making clinker

Raw materials used in cement manufacturing , maybe unless you view the clinkering process as igneous rocks in the making , a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result In practice, however, clinker composition is largely ....

Portland cement

Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker The materials in cement clinker are alite, belite, tri-calcium aluminate ....
