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 optimumideal 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.
Circuit p80 target size material in the ball mill.It can be measured and then increased through pump and cyclone adjustments.By so transferring the application of ball mill power from fine minus p80 product size to coarse material, circuit efficiency is increased and overgrinding is decreased.The other factor that determines overall.
Ball mill designpower calculation.Ball mill designpower 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.
Bond ball mill index test brmwi a bond ball mill index test bbmwi is a standard test for determining the ball mill work index of a sample of ore.The bbmwi is a measure of the resistance of the material to crushing and grinding.It can be used to determine the grinding power required for a given throughput of material under ball mill.
These nes proceed to the ball mill improving the ball mill ef ciency.Also, the plotted rod mill p80 value, as shown in figure 1, is 2900 m.If the rod mill nes are taken into account the rod mill product can be theoretically corrected to show a p80 of 1700 m, the plotted 80 per cent passing size divided by 1.
