process of raw materials for concrete

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.

Aug 27, 2015· The process is accordingly known as the dry process or the wet process of mixing. Dry process (modern technology) In this process, the raw materials are first reduced in size of about 25mm in crushers. A current of dry air is then passed over these dried materials. These materials are then pulverized into fine powder in ball mills and tube mills.

Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
