grinding efficiency of ball mill

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 length to diameter ratios for a given power rating will yield different material retention times the longer units being utilized for high reduction ratios and the Get a Quote Send Message
