-Balltop size (bond formula): calculation of the top size grinding media (balls or cylpebs):-Modification of theBall Charge: Thiscalculatoranalyses the granulometry of the material inside themilland proposes a modification of theball chargein order to improve themillefficiency:

Theball chargeand ore charge volume is a variable, subject to what is the target for that operation. The type ofmillalso is a factor as if it is an overflowmill(subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the totalcharge.
