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 ....
Bond Work Index
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5).
