  • hardgrove grindability index of petcoke

    Hargrove Grindability Index (HGI) A measure of the relative hardness of the coke in terms of resistance to grinding. An HGI below 35 usually means a very hard coke requiring considerable grinding before it can be properly sized to meet burner nozzle specifications for the pulverized feed to the furnace where the coke will be burned.

    The vibrated bulk density (VBD) is one of the most important calcined coke properties. In the context of changing green coke quality, a reliable forecast of the calcined coke VBD from small samples of green coke is required. To a certain extent, the VBD can be predicted from green coke properties, such as the Hardgrove Grindability Index (HGI) and the volatiles content.
