CORRELATION BETWEEN BOND WORK INDEX AND .
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 index would be expected to remain constant since it indicates the .
