Stirred media mills in the mining industry: Material ...

In stirred media milling, the energies experienced are typically much higher than the minimum threshold energy E min, and so Palaniandy assumed that E min = 0 (this is generally true for comminution of brittle particles, so long as stresses are high enough that low energy incremental breakage does not dominate ). Palaniandy found that Eq.
