Estimation of the Specific Energy Requirement for Size

Nov 08, 2016 Table 1 shows a comparison of the specific energy values calculated from Eqs. () and for the 100 mesh test sieve (S = 150 m) 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 relatively higher values, and for G values smaller than

THE OPTIMAL BALL DIAMETER IN A MILL

The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; Katubilwa and Moys, 2009; Erdem and Ergun, 2009)
