  • Analysis of Chemical Composition of Portland Cement in

    The calcination process between well-proportioned argillaceous and calcareous substances leads to the production of clinker. Portland cement is obtained when the produced clinker is mixed together with a predefined ratio of gypsum and milled together in a ball mill. The chemical composition of Portland cement involves both major and minor oxides .

    The raw materials are crushed and fed in the correct proportions into a grinding mill, where they are dried and reduced in size to a fine powder. The dry powder, called raw meal, is then pumped to a blending silo, and final adjustment is now made in the proportions of the materials required for the manufacture of cement.
