Interrelationship of coal grinding properties and coal

Aug 01, 1998The Hardgrove grindability index (HGI) is a widely used coal-quality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the high-volatile
