Bond Work Index Formula

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ....

Bond Ball Mill Work Index Determination

Bond Ball Mill Work Index Determination The average useful work input to the standard ball mill is 65 joulesRev with 115 joulesRev to the rod mill The crack energy Ce of the sample tested is found by dividing joulesRev by CmRev The standard work index can then be found by transposing Eq 16 and solving for Wi100...

Testwork: Bond crushing work index

The Bond low-energy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus...
