Hardgrove Grindability Index (HGI) & Standard Reference

The Hardgrove Grindability Index Standard Reference Sample (HGI-SRS) is a sample of coal used to calibrate instruments that are designed to determine the ease with which coal can be pulverized. The HGI value provides information for determining grinding power consumption and pulverizer capacities.

The Hardgrove grindability test and test machinery are designed and developed to characterize the relative grindability of coals. The Hardgrove grindability index represents a composite physico-mechanical property of the coal, embracing a number of specific properties such as hardness, strength, tenacity and fracture, and is a function primarily of coal rank and secondarily of coal

Hardgrove Grindability, Coal Analysis, Kentucky Geological

2019-10-7  Hardgrove Grindability. Hardgrove grindability is a measure of the relative ease with which a coal sample can be pulverized or ground to smaller sizes. All mined coals need to be ground to very small sizes (often powder size) before being utilized. For example, most steam coals (used to generate electricity) are ground to 60 mesh (250 microns
