Grindability - an overview ScienceDirect Topics

One of the most commonly used methods is the Hardgrove Grindability Index (HGI). HGI for coal is determined by grinding 50 g of sample in a ball and ring type mill for 60 revolutions, after which the product is sieved through a 200 mesh sieve (75 micron screen) (Speight, 1994). HGI is computed by measuring the undersize of the product.

COAL PHYSICAL TESTING - SGS

The Hardgrove Grindability test is a measure of coal’s resistance to crushing and attempts to reproduce the effects of continuous coal pulverization in a mill. A 50-gram sample of prepared coal of uniform size range is placed inside a grinding unit. The unit undergoes a standard number of revolutions under a specified pressure allowing steel balls within the unit to crush the coal sample. The coal fines are sorted and the quantity of coal less than a specified size is recorded and converted into a Hardgrove Grindability index (HGI) value. The HGI value is used by utilities to evaluate how coals will perform in their mills; this includes grinding power requirements and throughput capacities. Typical values lie between 30 (increased resistance to pulverization) and 100 (more easily pulverized). Experienced SGS technicians will ensure your HGI
