For the first stage of grinding, media will generally be in the 4″ to 2″ size (in some cases as high as 5″). In secondary finer grinding the initial charge will begin at around 3″ and in the case of balls will grade down to about ¾". Extremely fine grinding will dictate the use of 1½" and smaller balls. Grinding media is the working part of a mill.
