  • CEMENT RAW MATERIALS International Cement Review

    The raw materials used in cement manufacture are extracted in large quarries, typically with outputs of up to, or over, 2.5 million tonnes per year. Typically about 1.65 tonnes of limestone (1.5 to 1.8 tonnes) and 0.4 tonnes of clay are quarried for each tonne of cement produced. Large reserves of feedstock, particularly of limestone, are required to provide

  • How Cement Is Made Portland Cement Association

    Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process. The two processes are essentially alike except in the wet process, the raw

  • Cement Manufacturing Process: How the Cement is Made?

    In this process, the raw materials are first reduced in size of about 25 mm in crushers. A current of dry air is then passed over these dried materials. These dried materials are then pulverised into fine powder in ball mills and tube mills. All these operations are done separately for each raw material and they are stored in hoppers. They are then mixed in correct proportions and made ready
