Re: Hard Groove Index
I can tell you the meaning of it:
"..empirical ranking of the relative grindability or ease of
pulverization of a coal under standardized conditions.."
I suspect you need someone to test your material to determine your actual values. Maybe someone has some generic information floating around.

Re: Hard Groove Index
Some people have given values for the applications previously.
I am not sure if you could consider them "typical".
