  • Hardgrove Grindability Index

    Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined

  • hardgrove grindability index table

    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. DA: 49 PA: 47 MOZ Rank: 1

    The grindability of these fuels was then determined using a laboratory ball mill and by adapting the Hardgrove Grindability Index (HGI) test for hard coals. After grinding, two sets of results were obtained. Firstly a determination similar to the HGI test was made, measuring the proportion of sample passing through a 75 m sieve and plotting
