Cement Plant With Coal Firing To Minimise Cost

  • Cement Plants | Kidde Fire Systems

    Cement Plants | Kidde Fire Systems

    The Cement/Lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network.
