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 ...

Hardgrove Grindability Index analysis is the ASTM method of determining the hardness of coal when pulverized for steam generation or size reduction. Grindabilities typically range on coal from 35 – 110. Harder and less grindable coal rates a smaller HGI index number.
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 ...
