Accurate Scale Up

Additionally while techniques like the Bond Work Index and "scale up factors" are useful for coarse grinding, they can significantly underestimate grinding needs below 100 microns. Similarly Tower Mill laboratory tests typically use much finer media than can be used in full scale operation and testwork is done in "batch" mode.

Testing method for ball mills

 · The Bond ball mill test is designed to predict power in wet ball mill grinding circuit operating at a 250% circulating load. However, moving away from this condition reduces the accuracy of the test. Further, the Bond ball mill test does not predict the behavior of large rocks in a grinding circuit where the mode of breakage is impact dominated.
