Jul 01, 2017· The so-called JK Bond Ball Mill Lite Test (JK BBL) is a locked cycle grindability test conducted using the standard Bond laboratory ball mill. As distinct to the Bond grindability test, the test consumes approximately 2.5 kg of sample, i.e. half of the mass needed in the full test, due a reduced number of two to three locked cycles.

test is performed at a grinding size that, ideally, should be the industrial grinding size. In this case, the grindability test was performed for mineral characterization, and four sizes (45, 75, 125, and 250 m) were selected to perform the tests. Once these values were determined, the grindability …
