  • The Cement Manufacturing Process

    Cement Manufacturing Process. The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw materials in the

    From the grinding mills, the cement is conveyed to silos where it awaits shipment. Cement is shipped by trucks, rail, or barge. Finish Grinding . Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement

    The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore. The
