Raw materials for cement manufacturing

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalkLimestone is of predominantly fine grained crystalline structure, its hardness is between 18 to 30 of the Mohs scale of hardness and specific gravity 2 To 28 Limestone usually contains admixtures of clay substance or iron compounds, which influences its colorThe quality of cement clinker is directly related to the chemistry of the raw materials used Around 80–90% of raw material for the kiln feed is limestone Clayey raw material accounts for between 10–15%, although the precise amounts will vary Magnesium carbonate, which may be present in limestone, is the main undesirable impurity The levelCEMENT RAW MATERIALS International Cement Review

RAW MATERIALS IN CEMENT PRODUCTION

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide These components are rarely found in one type ofThe raw material production of cement plant can be classified into four steps: crushing, grinding, mixing and homogenizing Crushing: the limestone and other materials are crushed into small pieces by cement crusher, such as hammer crusher, cone crusher, jaw crusher, impact crusher, etc Mixing: according to the requirement of clinker, compoundPreparation Of Cement Raw Material | Cement Mill,
