Table 1 shows a comparison of the specific energy values calculated from Eqs. () and for the 100 mesh test sieve (S = 150 µm) and seven values of G in the range of 0.33–3 g/rev.It can be seen that at a G value of 1.5 both the equations give the same estimate of the specific energy. For G values greater than 1.5 the Bond equation gives …

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
