Nov 06, 2019· To help the grinding process, water and steel balls are added to the process which then form the charge in the mill. Ball mill charge contains a significant amount of steel balls and can become extremely heavy. For example, a large 24 foot (7.3 m) diameter ball mill charge typically weighs around 2 million lbs (907 tons).
