One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill A f80 6 mm would need a ball size of 75 mm

A quick check of the Rowland optimum feed size for this ball mill is between 3 and 4 mm operating either circuit you describe will be at least 15 inefficient compared a more conventional ball mill feed size The screen doesnt matter in terms of energy efficiency only more crushing or a small rod mill that will improve the energy efficiencyView Details
Based on his work this formula can be derived for ball diameter sizing and selection Dm 6 log dk d05 where D m the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mmView Details
feed size ball mill Feed Size VS Ball Size 7 replies One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill A f80 6 mmView Details
As the feed size is reduced further less of the 508 mm balls and more of the 254 mm balls are required for the maximum capacity attaining 100 of 254 mm balls for a feed size of 47 mm Fig 6 d The capacity difference between the best and the worst makeup ball mixtures was as high as 150 Download Download fullsize imageView Details
Material feed size 05 mm Final fineness 1 µm Product details RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy inputView Details
The ball size is often in the diameter range of 2075 mm The biggest size is chosen when the mill is used as a primary grinding mill For fine grinding of eg sands balls can be replaced by cylpebs which are heat treated steel cylinders with a diameter of 1240 mm and with the same length as the diameterView Details
Planetary Ball Mills are used wherever the highest degree of fineness is addition to wellproven mixing and size reduction processes these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy andView Details
