Our Company | Central Plains CementCentral Plains Cement

Cement manufacturing requires consistent and high quality sources of the four primary raw materials: calcium, aluminum, silica, and iron. Both facilities obtain the required calcium from limestone extracted from their own mines. Unusual for a cement plant, the Sugar Creek plant limestone source is an underground mine rather than on open pit quarry.

Utilisation of High Silica Low Grade Limestone

 · These coals are low grade with ash content as high as 35 per cent. During pyro-processing the absorption of coal ash increase the silica content in the raw meal making it difficult for production of quality clinker. In case of where high silica limestone is to be used, Pet coke and lignite are the best fuels to control the silica content.

CEMENT RAW MATERIALS

The overburden to limestone deposits is also used frequently as a source of silica, alumina and iron. Other mineral components (such as iron oxide wastes, silica sand, etc) are sometimes used to blend into the raw material mix to optimise the chemistry. The variety of raw material used worldwide for cement manufacture is very great.
