This test determines the Bond Ball Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements for sizing ball mills. The test is a closed-circuit, dry grindability test is run in a standard ball mill, and can be performed at sizes ranging from 595 mm to 37 microns. The normal finishing size is 149 microns.

The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior. [18] The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .

carried out with the Bond ball mill and rod mill grindability tests. As discussed earlier in this paper, it is important in this case to match the reduction size of the test to that desired from the industrial mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it ...
