## Bond Impact Crushing Work Index Test 80 -

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.

## Impact work index prediction from continuum
