Grindability an overview ScienceDirect Topics
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.
