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.

Hardgrove Grindability Index (HGI) The Hardgrove Grindability Index (HGI) is a measure of coals resistance to crushing. Read more. 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.

In the Hardgrove Grindability test, 50 g of a limited particle size range (16 #215; 30 mesh, or mm #215; 600 m) of coal is ground in a ball mill for 60 revolutions. The resulting coal is sized and the weight of the (lt;200 mesh) product is recorded and, by calibration to a reference coal, used in the calculation of the Hardgrove Grindability Index (HGI).

#0183;#32;Grindability tests which aim to analyse the grindability of biomass to 75 m are flawed, as the target size for optimal combustion of biomass and the setting for the classifier output from full scale mills is an order of magnitude of higher than this. The BWI test can be used to analyse the mill behaviour of biomass in a tube and ball mill.
The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. The grindability is useful in evaluating power requirements for grinding. To design a
