  • The Cement Manufacturing Process

    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 cement manufacturing process. After receiving cement raw materials from the Indian mining industry, limestone is transferred in raw mill for grinding into a fine powder.
