12/06/2013 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 empirically using a sample mill ...

The Hardgrove grindability index (HGI) is a widely used coal-quality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the high-volatile ...
