Portland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these

Depending on its deposit and composition, the cement raw material may contain a more or less big portion of water. Especially with high feed moistures, drying is of particular importance because the existing surface moisture has to be evaporated almost down to zero in the raw mill.

Technically, 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 determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.
