Every coal pulverizer is designed with a particular fuel grinding capacity or throughput at a certain Hardgrove grindability index (HGI), based on a defined raw coal size.Coal parameters affecting pulverizer output. While selecting a pulverizer, the coal characteristics play an important role. The Hardgrove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. The Hardgrove index of coal tells us about the ease with which it can be pulverized.
