Cement Manufacturing Industry Process Flowsheet

Main operation involved in the cement manufacturing flowsheet:

  • Raw material blending operation
  • Grinding of raw materials
  • Kiln heating
  • Pulverizing the finished product

Four important components that the final cement product should have are Di-calcium silicate, Tri-calcium silicate, Tri-calcium aluminate, Tetra-calcium aluminoferrite these components are varied to obtain the required strength of the cement. An ideal cement composition would contain 25, 60, 5, and 10 % of the above components respectively. Along with them magnesium oxide is also preserved in the cement clinker.
