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.
Determination of work index is time and labour consuming therefore, grindability index, most commonly known as hardgrove grindability index (HGI) is preferred for predicting the grinding behaviour of coal and energy consumption requirements of mill (Tichanek, 2008).
