  • Raw materials - Understanding Cement

    The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition; Quarry management is an art; most quarries will probably have "good material

  • Cement Production Process | Regain Materials

    Cement is produced by mixing and fine-grinding clinker, gypsum and mineral components (e.g. limestone, pozzolana, fly ash or granulated blast furnace slag, silica fume) in cement mills. Gypsum is added to control cement setting, i.e. the hardening process. Mineral components are added to reduce the clinker portion in cements and introduce special product properties. Pure Ordinary Portland Cements (OPC)
