Use of raw materials in the cement industry. The most important base materials in cement include limestone, clay or the naturally occurring mixture of the two, lime marl. Geologically speaking, about 90 per cent of the quarried limestone dates back to the mesozoic (Cretaceous, Jurassic, Triassic) and is thus between 65 and 250 million years old....Chat Now
Mining Of Raw Material In Cement nnguniclub
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
Aug 30, 2012· Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite.

Cement, How It Is Produced Mine Engineer.Com
Cement manufacture, like many other manufacturing processes, begins at the mine, where the raw materials like limestone, silica, aluminates, feric minerals and others are obtained. Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell.
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.
