 ### 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 kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 m If the breakage characteristics of a material remain constant over all size ranges the calcul ated work ### Kinetic grinding test approach to estimate the ball mill

Kinetic grinding test approach to estimate the ball mill work index 345 Kinetic grinding Exactly 700 cm3 of passing 3 35 mm material from each sample was progressively grounded in periods of 0 33 1 2 4 and 8 minutes Our experience has shown that the required number of revolutions to achieve the circulating load of 250% ### HOME Product ball mill operatng work index calculation
