Hardgrove Grindability Index - Wikipedia

50 g of air dried coal featuring a grain size in the range between 0.6 and 1.18 mm are filled into the sample mill and a weight is put on the mill's grinding stone. After 60 rounds the grinded coal is put on a sampling sieve. Factor D equals the fraction of the coal passing through the sieve of 74 μm corresponding to 200 mesh. HGI is calculated from D as follows: $${\displaystyle H=13+6{.}93\cdot D}$$This procedure only results in relative values because the sampling mill is calibrated using a re
