Manufacturing Process-White Cement

Production of White Portland Cement involves five significant manufacturing stages namely: Crushing, Raw meal grinding, Clinkerisation, Cement grinding and Packing for despatch.

  • At Raw mill, crushed limestone, clays and feldspar of desired chemical compositions are fed through electronic weigh feeders.
  • Clinkerisation is the heart of cement manufacturing process, where the raw material is fed to pre-heater at controlled rate through electronic weigh feeder. The feed enters the kiln through cyclones and fuel is fired at the kiln outlet end.
  • Clinker and gypsum are fed to the cement mills through electronic weigh feeders at controlled rate and ground in ball mills. The classifier (high efficiency separator) controls the fineness of white cement. The finished product of desired chemical composition and physical properties is transported to Cement Silos for storage.
  • White cement is drawn from cement silos, for packing in bags by electronic rotary packer and in small pouches by Fill, Form and Seal machines.
