Hardgrove Grindability Tester measures relative ease of pulverization of coals compared to standard coals in accordance with ASTM D409 Hardgrove Machine Method.The resulting Hardgrove Grindability Index (HGI) provides a measure of energy required in a grinding process or a measure of yield for a given energy input.
The results are converted into the equivalent Hardgrove grindability index. High grindability indices refer to easily ground coals. Prior to the experiments, each Hardgrove machine should be calibrated with reference samples of coal. The reference indices used are 40, 60, 80 and 100.
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

In a Hardgrove test, samples are crushed to a specified size, air-dried, and weighed, then run through a laboratory grinding (milling) machine for 60 grinds (rotations). The milled sample is then placed on a sieve of set specifications. The amount of sample that passes through the sieve is used to calculate the Hardgrove grindability index.
Mining Hardgrove Grindability Index (HGI) The Hardgrove Grindability Index (HGI) is a measure of coal’s resistance to crushing. Grinding studies, and the resulting HGI, allow many different types of coal users to evaluate how coals will perform in their mills, allowing them to estimate grinding power requirements and throughput capacities.
