What are the raw materials used in cement production?

The exact composition of the raw materials and the manufacturing process can vary depending on the type of cement being produced, such as Portland cement, white cement, or blended cements.

Cement

Raw materials Composition. Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

Raw materials preparation: The raw materials are crushed, ground, and blended to form a fine powder called raw meal. Clinker production: The raw meal is heated in a kiln at a temperature of about 1450°C, which causes chemical reactions that result in the formation of clinker. Clinker cooling: The clinker is cooled in a cooling chamber.
