The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness. In general, cement raw materials are mainly quarried, and so contain a certain amount of natural moisture. Attempting to grind a wet material is unsuccessful because an intractable "mud" forms. On the other hand, it is much easier to dry a fine material than a coarse one, because large particles hold moisture deep in their structure.

Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale. Methods of cement manufacturing 1- Wet process ___ grinding and mixing of the raw materials in the existence of water. 2- Dry process ___ grinding and mixing of the raw materials in their dry state. The process to be chosen, depend onthe nature of the used raw materials.
