  • ball mill design/power calculation

    ball mill design/power calculation

    The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

    how to charge the ball in cement mill

    The mill is designed to handle a total ball charge of 3245 t at loading with a percentage filling of 295 in both the chambers Both the chambers of the cement mill were charged with 80 of the designed charge which works out to 86 t in Ist chamber and 172 t in the IInd chamber

  • mill steel charge volume calculation

    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

    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

    how to estimate the wear rate for ball mill- page 1 of 10

    Dec 08, 2009 · Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated. More simply and quite adequate is to keep a record of material ground and of charge added …
