May 20, 2021 Hardgrove Grindability Index. HGI measures the grindability of coal. Being an index, it has no unit, simply a number. The harder the coal, the lower the index number. Conversely, the higher the HGI, the softer and more grindable the coal and the higher the mill loading, as shown in Graph 1. Ash softening/fluid temperatureMay 20, 2021 Hardgrove Grindability Index.

The HGI varies with coal rank increasing (greater ease of grinding) with ...HGI is determined through a multi-step procedure: A 50-gram sample of prepared coal that is uniform in size is placed inside a grinding unit. The unit undergoes a standard number of revolutions under a specified pressure. Steel balls within the unit crush the coal sample. The coal fines are sorted and the quantity of coal less than a specified size is recorded and converted into a Hardgrove Grindability Index (HGI…
