Blending A first approximation of the chemical composition required for a particular cement is obtained by selective quarrying and control of the raw material fed to the crushing and grinding plant. Finer control is obtained by drawing material from two or more batches containing raw mixes of slightly different composition. 11 pages, 5072 words

The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage. In the case of raw materials, attempts have always been made to minimise the amount of crushing needed by extracting the rock in the finest possible state.

Requirement of White Cement Raw Material. The mineral composition of white cement clinker is basically the same as that of ordinary portland cement (OPC) clinker, mainly C 3 S and C 2 S. The difference is that there is little iron phase mineral C 4 AF in white cement clinker, which is because Fe 2 O 3 has a great impact on the whiteness of cement.
