to verify the new power draw approach, detailed surveys of the 14 ball mill circuits at 6 different plants were carried out. the ball mills sampled in this study are ranging in diameters from 3.2 m to 4.8 m. design and operational parameters of the ball mills sampled are given in table 1. table 1.

for a single size of make-up ball, the mass fractions in the mill within the size ranges are calculated from: 11 m k = d k u 4 − δ − d k l 4 − δ d max 4 − δ − d min 4 − δ where d k u and d k l represent the upper and lower boundaries of the ball size interval k, d max is the largest ball size in the mill, and d min is the smallest ball size in the mill which is still retained. δ is a constant, which relates to wear laws.

but remember it all depends on your mill feed size after pregrinding. this is the raw mill not the finish mill. so wi should be 11 and density of 2.67 as normal kiln feed. i used d80 of 3500 micron to be on safe side and got max ball dia. of 41 mm use 50 mm steel balls .

calculate surface finish when using a ball nose end mill. menu searchtext home / resources / engineering calculators / end milling / ball nose surface finish. ball nose surface finish. unit: these calculations are based upon theoretical values and are only intended for planning purposes. actual results will vary.

mill effective diameter = 2.23 m . 335 is a constant used for dry grinding with steel balls in the mill. actual size of media is taken is lower than the calculated value. it is around 80 to 90 mm. if you wants to reduce the maximum ball size, thenreduce the feed size by using pre-grinding operation.

i need info about the ball mill size to the balls used.i had opted for steel ball due to cost effective purpose. needed detail about the relationship between shapes of grinding media balls and

2012515the ball size in a mill has a significant influence on the mill throughput, power for industrial mills the optimal ball diameter in a mill 333 the grinding efficiency of the narrow particle size fractions with ball. chat online; ball mill size calculation. in this study, simplification of the calculations and experimental procedure of
