Secrets of the Bond Ball mill grindability test

feed size distribution is different to a standard Bond ball mill work index test. A series of 10 samples for an Andean copper project were treated to both the SAGDesign (and Sd_bwi) test and the standard Bond ball mill work index test with 180 µm closing screens. The SAGDesign results (with the non-standard ball mill feed) are given in Table 1.

Bond Work Index

Laboratory measurement showed that the product size of gold was 75% minus 63 μm. A standard ball-mill Bond test indicated that the grindability was 2.28 grams per revolution at a test screen size of 106 μm. The ore was ground in a wet closed circuit ball mill at a throughput rate of 150 t/h. Estimate the work index for a mill of I.D. 2.0 m.
