mill throughput capacity. the sag test reproduces commercial sag mill grinding conditions on 4.5 l of ore and cfdia = if the ball mill diameter is greater than 8 ft, the mill diameter factor as determined by . data input :all data required by the calculation routine must be defined in each .

the ball mill is a tumbling mill that uses steel balls as the grinding media the length of the cylindrical shell is usually 115 times the shell diameter figure 811the feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight

the pulp should have a volume of 18.5*25%=4.56m3 in the ball mill. then the minimum grinding time = 4.56/1.35=3.38min note: when the grinding time is the shortest grinding time, it is ideal when the large block is directly ground to the granule size, and there is no over-grinding phenomenon. this value is only for theoretical calculation.

correlations for the grindability of the ball mill - citeseerx. finally the calculated values of the fines in terms of the grindability of the mill obtained through the balls, time of grinding, particle density and speed of the ball mill rpm have been considered for the present capacity for proper grinding .
