Some Methods for Calculating Hardgrove Grindability Index

From a study of large number of determined values of Hardgrove Grindability Index (H.G.I.) of all major types of Indian coals in has been found that H.G.I. of coals is mainly dependent on two factors: (i) rank of the coal and (ii) the amount of ash in it. It has been established that volatile matter together with the moisture of coals (both reported at 60% R. H. and at 40º C) is very closely

Bond Grindability Test Procedure

The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. The grindability is useful in evaluating power requirements for grinding.
