Dec 30, 2015 This transfer of energy depends on various variables, such milling time, ball weight ratio, ball number, and angular velocity of the ball mill plate. The transfer of kinetics energy to the powder occurs when the powder comes between the balls, converting cellulose into small pieces [ 28 – 30 ]

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
