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.

Composite samples for each of the three Murray Brook drill holes were submitted for grindability test work. Rod Mill Grindability Indices for the Murray Brook bulk sample materials averaged 14.6 kWh/t with a hardness percentile of 55%. Bond Ball Mill Grindability Indices averaged 10.7 kWh/t with a hardness percentile of 10%.

Metallurgical Laboratory Equipment Test Methods

2020-5-13  The grindability of an ore is determined by special grind tests whereby the screen analyses of the products from the grind tests are directly compared to results secured on certain standard grind test ores. Samples of ores of different grindability have been secured from actual milling plants where all grinding data are known.

The test work determined the Bond ball mill work index and hardness parameters related to semi-autogenous mill grinding (S) and high pressure grinding rolls (HPGR) crushing. The grindability test results indicated that the sample is moderately hard for grinding by ball mills but is very hard for milling by S mills.
