The sizing of ballmillsand ball milling circuits from laboratorygrindingtests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teachmill...
Thegrinding mill’s productioncapacityis generally calculated based on the newly generatedpowder oreof less than 0.074 mm (-200 mesh). V — Effective volume of ballmill, m3; G2 — Material less than 0.074mm in product accounts for the percentage of total material, %;
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a5′ x 5′Ball Mill has a working diameter of 5′ inside the liners and has20 percent more capacity than all other ball mills designated as5′ x 5′where the shell is5′inside diameter and the working diameter is only 4’8″ with the …

IsaMill - Wikipedia. The IsaMill is a stirred-mediumgrinding mill, in which thegrindingmedium and theorebeing ground are stirred rather than being subjected to the tumbling action of older high-throughputmills(such as ballmillsand rodmills).
The rodsgrindtheoreby tumbling within the themill, similar to thegrinding ballsin a ballmill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.Rod millsaccept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
