Besides, the Bond test involves a much more complex procedure and is more laborious than the Hardgrove test. Therefore, for various thermal power plants using coal and limestone, some improvement in mill efficiency and energy cost can be expected if the same grindability test is used for both coal and limestone (Hower et al., 1992).
