There is also a JKTech Bond Ball Mill Work Index Light. Basically only does the BBMWI to 3 cycles instead of the steady state. Requires less material ie 3kg, costs less even if you do duplicates. Apparently based on their data base data they have an average error of 4% compared to 3.5% for the full BBMWI. Regards, Chris P Peter Amelunxen

Bond Tests Mining Sgs. Similar to a comparative work index, this test is an open circuit dry batch grindability test run in the standard bond ball mill for a set time.It can be used at mesh sizes from 65 to 200 mesh normally 100 mesh.The test requires calibration against the standard bond ball mill work index test to estimate the work index.

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 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the …

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
