The distribution of particles in a batch mill was observed to vary along the axis of the mill. The centre of the mill was overfilled with particles, U>1, while the regions near the mill ends were underfilled, U<1. The opposite was true for the grinding media. The data reported was based on measurements of particle distribution along the mill

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 ...
