Interestingly from the results in Fig. 13 (including the RMS and spectral frequency analysis), the phenomena (noise reduction with time in ball mills) appear to differ in the present study where a laboratoryscale SAG mill is employed. The possible explanations could be associated with the breakage mechanisms of the AG/SAG mill.
