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.
Hardgrove grindability index (HGI) can be estimated from the test. A higher index indicates the coal is easier to pulverize. This is opposite to the pattern found with the Bond work in-dex where soft mineral ores generally have low work indices. Aplan, Austin, Bonner, and Bhatia (1974) and Aplan (1996) have shown a correlation between HGI and W i
