andesite bond ball mill work index
Geometallurgy Wikipedia
The Bond ball mill work index test is thought to be additive because of its units of energy nevertheless, experimental blending results show a nonadditive 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 .
