Hardgrove grindability index and approximate work
2019-7-25 · The Hardgrove test is a standard method used wide-ly in the coal industry. To determine the relative grindability of coal, i.e. whether it is easy or difficult to pulverize, the Hardgrove grindability index (HGI) can be estimated from the test. A higher index indicates the coal is easier to pulverize.
