The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.

Fig. 5(c) shows the corresponding cross-sectional view, and it can be clear seen that the columnar grain does be surrounded by one overlayer, and the overlayer is composed of lots of black dots. Meanwhile, the diffraction spots and rings of overlayer (indicated by red ring area in Fig. 5 (c)) demonstrate one polycrystalline carbon ring.

constant ball load of 28%. In the pilot scale experiments, the Magotteaux ball mill at Frank Concentrator was equipped with a Sensomag sensor for measuring the toe and shoulder angles of the slurry and ball load based on the principle of conductance and induction, respectively. The mill was configured to operate as a RoM ball mill.

The results of observations of the cross sectional microscopic structure in the vicinity of ruptures in a 30% reduction ratio specimen and related scanning electron micrographs are shown in Fig. 9. The hydrogen-uncharged specimen had ruptured in a ductile manner and the entire surface of the fracture is dimpled ( Fig. 9(a) ).
