A cement ball mill is generally divided into two or three grinding compartments. The larger the length-diameter ratio of the ball mill is, the more compartments there are. For dry ball mills used in the closed-circuit grinding system, when divided into two compartments, the first compartment length accounts for 30% – 40% of the total length ...

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 ...
