Raw Materials Used For Manufacturing of Cement

Raw materials used for manufacturing of Portland cement are found naturally in the earth crust. It is made primarily from calcareous materials, argillaceous materials and gypsum. Calcareous materials containing limestone or chalk and argillaceous materials containing an oxide of silica-alumina and iron are found as clay or shale.

What Is Raw Material Preparation In Cement

The raw material preparation stage of cement manufacture results in the production of a rawmix that is in a suitable state for feeding to the kiln in which it is converted by heat into clinker. This is a stone transformation. The rawmix consists of a mixture of materials that will react together to form the calcium silicates that confer on ...
