  • 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 Charge and Grinding Efficiency Grinding

    Reducing the ball charge will reduce the grinding capacity, and the comment on installing a grate discharge is a good one as it will let ore out sooner, thus minimizing overgrinding, which will occur if the mill is (temporally) too big, or one chamber is too big in a multi chamber mill. But the reduction is not a direct reduction (50% fewer balls 50% less grinding) as there is a factor from

  • Ball Mill Charge Grinding & Classification Circuits

    Ball size and ball grade is determined by the feed ore size and hardness, plus the PH level of the slurry. The ball charge is determined by the operator targeting the balance between grind and throughput, the higher the ball charge the more aggressive the milling becomes. With softer oxide ores lower ball charges are usual however the harder sulphides does need more media energies to meet the

  • Mill Steel Charge Volume Calculation

    We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or
