The Hardgrove grindability index (HGI) is a widely used coal-quality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the …

Hard groove grindability index (HGI)The HGI determined for fresh coal received at the stack yard was 60, whereas after getting exposed to the atmosphere in stackyard for 6 months, index was found to be 85. The sample of February 1998 showed again a higher value of 95. This indicates that, due to weathering, coal become soft and fragile.

The Hard-grove grindability index (HGI) can be then estimated from the test. The higher the index is the easier the coal to be pulverized. However, this index can not be used to size a pulverizer and mill power directly. Only the specific energy, mill power over capacity, is a main parameter for mill sizing.

Coal is a carbonaceous ore contains maceral and minerals with different properties. Due to the presence of high mineral content, the mineral beneficiation process is adopted where the liberation of inorganic minerals plays key role. As coal is a soft material, use of impact mills generates coal with homogeneous distribution of minerals.

mill capacity the capacity of mill depends on the hard groove grindability index, the moisture content of coal & the pulverised fuel fineness output required. operating parameters maintain mill outlet temperature between 70-80c.

Grindability of coal is generally estimated by two indices: (a) work index in which energy consumption for obtaining product of constant fineness is measured; and (b) grindability index in which fineness of final product is measured for same grinding work of the standard samples. ASTM, 2004 (D409-02) was followed for determining hardgrove ...

The Hardgrove Grindability Index (HGI) is a measure of coal's resistance to crushing.
