coal crushing work inde

The Hardgrove grindability index (HGI) is the most expedient.There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production. Get price

Table 2 compares HGI, drop strength, abrasion resistance (Tumble Test) and water resistance data for the −4 mm coal only briquettes. These data distinguish the briquettes of coals A and B, which are two of the three lowest HGI coals in the set, as having significantly lesser abrasion and water resistance than the higher HGI coals.

Hardgrove Grindability Index (HGI) | SGS

Hardgrove Grindability Index (HGI) 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.

Metallurgical Coal – IspatGuru

 · The strength and density of coke is particularly important when it is used in a BF, as the coke supports part of the ore and flux burden inside the BF. Metallurgical coal possesses the ability to soften and re-solidify into a coherent, porous mass, when heated from 300 deg C to 550 deg C in the absence of air in a confined space.

Steel Glossary | Glossary of Terms | Platts

The quality of coke has a significant influence on furnace productivity and iron production costs. Coke is produced by heating coal to about 1,100 o C in a reducing (oxygen deficient) atmosphere. This is done in coke ovens, and volatile compounds like tars are released along with hydrogen and methane to leave a carbon-rich product.
