    The 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 level of magnesia (MgO) in the clinker should not

  • Energy and exergy analyses of a raw mill in a cement

    01/12/2006· Raw materials, including limestone, chalk, and clay, are mined or quarried, usually at a site close to the cement mill. These materials are then ground to a fine powder in the proper proportions needed for the cement. These can be ground as a dry mixture or combined with water to form slurry. The addition of water at this stage has important implications for the production process and for the
