Since 1952, Bond's equation has been used as a standard to predict the specific energy of grinding for a given duty. The Bond's equation considers that the exponent is constant for all conditions. Hukki, in 1961, pointed out that the exponent is a function of the particle size, and concluded that the Bond's equation applies successfully …

Rather than using a lab scale Vertimill, which suffers from scaling problems, this test utilises a lab scale ball mill that is smaller than in the Bond and Levin tests, and uses 19 mm media (typical of industrial Vertimills) [8], to carry out a series of batch grinds on the feed material at different energy inputs. This allows for better ...

Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills. They have much higher specific grinding energy and from there are for production of finer products than conventional ball mills.
