Effects of the speed ratio on the efficiency of planetary mills

As indicated earlier in the introduction section, it has previously been shown that 1/t ig and the energy milling power provided by a mill are directly linked [18].In Fig. 4, 1/t ig is plotted as a function of k for the different ω d and BPR, from which the multi dependence of k, ω d and BPR on the milling efficiency can be observed. In this figure, it is more clearly visible as the best ...
