Coal Mill Hardgrove Power Consumption
HGI is a reasonably good indicator of the expected milling behaviour of a coal. Low volatile metallurgical coals are generally softer coals with a Hardgrove Grindability Index of around 80. As these coals are very easy to mill, there are savings from reduced mill power consumption for a given coal throughput.

PRACTICAL ASSESSMENT OF GRINDING CAPACITY AND …
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 - Wikipedia
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 ...
