Another important task associated with the ball mill grinding operation is to establish a sound basis for carrying out scaleup of ball mills based on laboratory or pilot scale test work. This requires studies related to the influence of mill diameter on production rate of particles of a desired size distribution.
work indices for the AG/SAG mill and ball mill can be reorganised as [7] and [8], where B'Wio and A'Wio are the corrected operating work indices and WAG/SAG, WBM are the respective power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2),

The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work
