Cement Ball Mill Sizing Explanation

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

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.
