2017-8-10 Effect of ball charge distributions and mill types on parameter of particles circularity for fine- and coarse-grained feed are shown in Fig. 6(a and b), respectively. As it can be seen, circularity of particles in all tests is higher for OBM than CBM, for both fine- and coarse-grained feeds. The difference of circularity depends on ball mill types.

Optimization of mill performance by using
2015-4-16 Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
