  • Cement Milling

    Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.

  • Millstone

    Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains. Millstones come in pairs: a convex stationary base known as the bedstone and a concave runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones.
