Grindability Index Indicates the ease of pulverizing a coal in comparison to a reference coal. This index is helpful in estimating mill capacity. The two most common methods for determining this index are the Hardgrove Grindability Method and Ball Mill Grindability Method. Coals with a low index are more difficult to pulverize. (c)
Sep 10, 2013· The Bond- and the Hardgrove methods are widely used for the determination of brittle materials' grindability. Generally, the determination of the Bond work index of inhomogeneous materials can be carried out with high deviation using the conventional grindability apparatuses and methods, because of the highly different grindability of components.
