    Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index therefore it has no unit. The smaller the HGI the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors HGI is determined In my case we are using both Hardgrove and Bond work indexes for different Kaolin samples. I am looking for to secure more information about HGI of clays especially different Kaolin samples.

    Meanings of HGI in English As mentioned above HGI is used as an acronym in text messages to represent Hardgrove Grindability Index. This page is all about the acronym of HGI and its meanings as Hardgrove Grindability Index. To determine the relative grindability of coal i.e. whether it is easy or difficult to pulverize the Hardgrove test is a standard method widely used (Klima 1999). 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.
