The Bond low-energy impact crushing work index ( rmally, 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.
Jun 16, 2015 Sizing a crusher can be done reliably calculated thanks to the Impact Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.

11 Crushing and classification. 2021-5-14 based on the ratio of the volume before to the volume after crushing. Thus, the energy required is directly proportional to the size reduction, e.g. the same amount of energy is required to go from 2 to 1 cm as from 1 to 0.5 cm. = i f K ln x x E k (11.4) Bond (1952) suggested that the total work required to break a cube of size x is proportional to x3.

Bond F. C., Crushing Grinding Calculations , Reprint from British Chemical Engineering, Allis-Chalmers Publication 07R9235B. Bond Low Energy Impact Test. The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers .
The tests were carrying out to determine the power consumption by crushing brown coal under conditions based on the Third Theory of F. C. Bond. The power consumption tests are in the units of the Bond Work Index (Wi). The mean value of Wi for the tested brown coal from Handlov mine (Slovakia) was Wi = 9,76 kWh sht.
