An impact pendulum that follows strictly Bond's standard for crushability measurement (Bond, 1947, Bergstrom, 1985, Tavares, 2007) has been used, which allows calculating the crushing, or impact, work index.The test consists of dropping two pendulum-mounted hammers simultaneously against individual particles of size ranging from 75 to 50 mm that are sitting on a pedestal ().

Track 4 contains the average impedance of the image in Track 5 and a cement-bond index (CBI) as a quick indication of the degree of bonding. Tracks 4 and 5 imart clarity to the interpretation of Fig.8 by more clearly showing no cement above X80 depth units, good cement below Y20 depth units and questionable bonding in between.

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.

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 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work
