Optimum choice of the make-up ball sizes for maximum
Sep 01, 2013 As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
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 case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and ...

Ball Mill Critical Speed - Mineral Processing Metallurgy
A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
