wikipedia ball mill grinding efficiency

a)Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, andestablished 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 …
