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 HGI-SRS is prepared in a series of steps

Hardgrove grindability index and approximate work index of

The Hardgrove test is a standard method used wide-ly in the coal industry. To determine the relative grindability of coal, i.e. whether it is easy or difficult to pulverize, the Hardgrove grindability index (HGI) can be estimated from the test. A higher index indicates the coal is easier to pulverize.

Hardgrove Grindability Index Wikipedia

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 according to the following procedure:
