The Bond lowenergy 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 perspecimen test where individual specimens of prepared rock are handpicked by the test operator and placed into the apparatus.

FIGURE 4: BOND CRUSHING WORK INDEX v. UNCONFINED COMPRESSIVE STRENGTH highlighting three rock types Figure 4 displays Wi C and UCS values separated by the major rock types from a single African mine. The three rock types do show a mild correlation between crushing Work Index and UCS R values between 0.1 and 0.4.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic 38 measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

20091214The Bond crushability index, which is estimated using a standard impact crushability test, is suitable for crushing21. Because the jaw crusher was modelled in this study, the Bond crushability index of the rocks studied was determined. To study fracture mechanisms of the rocks in the processing zone of a crusher, a cubic and a spherical

2014627The Bonds standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatthours 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

The 80 passing size P of the broken rock must be measured by size analysis or must be estimated to obtain the blasting work index. Two blasting tests Bond, 1954 on Taconite iron ore in Minnesota five years ago gave work index values of 14.5 and 13.5, or an average of 14.0, which compares with 14.7 recently obtained in crushing this ore in ...
