Cement Milling. Cement milling is usually carried out using ball mills with two or 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.The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it. Ball mills are classified as attritor, horizontal, planetary, high energy, or shaker.
