In the dry process, crushed raw materials mixed in a certain proportion are ground and mixed without water to form a raw meal before being transferred into a kiln. The slurry or raw meal is then heated to up to about 2,700 degrees Fahrenheit (or about 1,450 degrees Celsius) in a huge cylindrical steel kiln, which chemically alters it.

Raw materials for cement manufacturing

The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The chemical composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures as iron hydroxide, iron sulfide, sand, calcium carbonate, etc. Clay is used as an argillaceous component of raw mix.

Manufacturing Process – Continental Cement

The raw materials are analyzed in real-time using cross-belt analyzers and in the plant laboratory, blended in the proper proportion, and then ground even finer. Plants grind the raw materials with heavy, wheel-type rollers that crush the materials into powder against a rotating table. After grinding, the material is known as raw meal and is now ready for the preheater tower.
