4. HARDGROVE GRINDABILITY INDEX (HGI) • The Hardgrove Grindability index is designed to determine the ease with which coal can be pulverized. • It measures the grindability of coal and is a qualitative measure of coal. • It provides information for determining grinding power consumption and pulverizing capacities.

ABSTRACT Partial substitution of pulverized coal (PCI) by renewable biocarbon for blast furnace injection is a practical approach to reduce GHGs in the steel production sector. For using biocarbon as feedstock, it is critical to measure its grindability to understand its milling behavior compared to that of typical PCI coal, and thus help decide on adjusting grinding process of existing ...

About Pulverized Coal Injection (PCI): PCI is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). It is an essential instrument for modern blast furnace ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.
