Abstract: Ball drum mills area commonplace in grinding offerrous and non-ferrous metals, and a cement production in the world. A significant shortcoming of these mills is high specific energy consumption on grinding. A material grinding process in ball drum mills is executed by grinding bodies that move in a transverse section of a mill drum.
