coal mill hardgrove power consumption

The Hardgrove Grindability Index Standard Reference Sample (HGI-SRS) is a sample of coal used to calibrate instruments that are designed to determine the ease with which coal can be pulverized. The HGI value provides information for determining grinding power consumption and pulverizer capacities.

Hardgrove Grindability Index (HGI) Mining SGS. 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.

Optimizing moisture content of lignite in advance is an effective way to improve the pulverization process, to enhance thermal boiler efficiency, and hence to reduce coal consumption. The present work was aimed at investigating the effect of occurrence and content of moisture on the energy-size reduction of lignite in a Hardgrove mill.
