Index Bond Ball Mill Labtech The standard bond ball mill work index test procedure is firstly to stage crush the feed to minus and size a representative sample the test then involves a series of batch grinds in a standard bond mill a bond mill is by with rounded corners a smooth lining and runs at 70rpm the charge consists of 285 balls weighing a More Details Index Bond Mill Of Mining
BOND S WORK INDEX WHAT IT IS AND WHAT IT ISN TThe reason for this variation in ball mill work index is because the ore at Mt Milligan has an intrinsic exponent of in the 100 µm to 200 µm size range not the exponent empirically measured by F Bond The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energy
