Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous.
Ball loading capacity The volume of the grinding medium is the percentage of the effective volume of the mill, which is called the filling rate of the grinding medium. The size of filling directly affects the number of shocks, the area of grinding and the load of grinding medium in the grinding process.

Generally, a mill's working volume is 25% of the total volume. That is 20% theoretical void space between the media spheres plus 5%. • 100 gallon mill • 50 gallons media • 25 gallons of solids . For wet milling, the fill level is between 25% and 60% of the mills volume depending on the percent solids in the liquid and the viscosity. Typical viscosity handled in wet mills is between 2,000 to 3,000 centipoise.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in caseâ€. Well, this safety factor can cost you much in recovery and/or mill liner wear and ...
