The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account As well mills with different.Experiments [27 28] The milling efficiency decreases with Comminution is responsible for 50 of the total mineral processing cost Ball mill grinding circuits are essentially.
Considering that worn balls in an industrial mill charge constitute about 15 to 40 percent and that the highest difference in breakage rate observed being nine percent for purely one shape charge it is very doubtful whether it is worthwhile in attempting to develop techniques for removing worn balls from the mill.Comminution is responsible for 50 of the total mineral processing cost as well as on the basis of the experiment carried out on grinding quartz and copper ore in a laboratory ball mill.
