Hardgrove grindability index [ ′här‚grōv ‚grīn·də′bil·əd·ē ‚in‚deks] engineering The relative grindability of ores and minerals in comparison with standard coal chosen as 100 grindability as determined by a miniature ball ring pulverizer Also known as Hardgrove number
The grindability and abrasive behavior of the blends were measured using Hardgrove grindability index HGI and Yancey Geer and Price methods respectively Further the coarser 75μm and
Grindability measurement as a testing method can be divided into two general categories the Bond Gbg and the Hardgrove grindability index HGI Grindability of coal and minerals is influenced
Hardgrove Grindability Hardgrove grindability is a measure of the relative ease with which a coal sample can be pulverized or ground to smaller sizes All mined coals need to be ground to very small sizes often powder size before being utilized For example most steam coals used to generate electricity are ground to 60 mesh 250 microns

HGI Hardgrove Grindability Index is a parameter that states the level of ease of grinding coal The higher the HGI value the easier the coal is crushed In addition HGI can find out the level of coal hardness where the lower the HGI value the harder the coal is or not easily crushed Therefore this study aims to analyze the effect of the
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

A charge of 50 g [ or ] g of coal was taken from analytical sample for performing grindability test in Hardgrove grindability machine Fig 3 After 60 revolutions of HGI grinder the ground coal was screened for 10 min on 75 micron sieve The weight of undersize was measured and HGI was calculated by following relation
Hardgrove grindability index estimation apparatus The experiments were performed on 70 coal samples for which respective values of the HGI were determined Prior to the experiments all coal samples were dried in ambient air until reaching the equilibrium moisture content Depending on the meteorological conditions
This test method covers the determination of the hardgrove grindability index HGI of those petroleum cokes that contain no dedusting additive The procedure for this test method is the same as in Test Method D409 Sections of this test method contain the significance and use of the HGI of petroleum coke preliminary sample preparation
