The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill. ... The grinding mill output will vary considerably with the Work Index. If the feed size was 13,000 micrometers for the same grind ...

Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.

A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semiself locking taper. 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.

Second, it was found that the ratio of the mill cylinder's diameter to the largest ball size should be at least 6:1. For instance, in Bond's ball mill work index test, the ratio was 8:1, and in Lee's (2019) grinding kinetic test, mm balls were chosen to match a U 20 cm mill with 12 cm lifters . Furthermore, it is assumed that ...
