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. An empirical model from "Emerging Trends in Mineral Processing", 2005, is ...

According to the need of customers, ball mills can realize both wet and dry production. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter. Feed particle size: less than 30mm. Production capacity: 22-250 tons / hour.
In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.
Stronger pellets were produced from the HPGR products, with a lower binder requirement (Ehrentraut and Rao, 2001) The pellets generally are more uniform in size; for example nearly 90% of the pellets were between 8.0 and 12.5 mm, compared to about 55% in case of the ball mill products.Therefore a higher loading on the grate may be possible with the same pressure drop at the …
