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. To design a ...
Bond Work Index (BWI) Hardgrove Grindability Index (HGI) tests for biomass coal. BWI can predict the potential for mill choking of biomass in a tube and ball mill. HGI is a poor method of predicting grindability of biomass in vertical spindle mills. Pellets should be composed of predensified particles close to the target size.

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.
The coal fines are sorted and the quantity of coal less than a specified size is recorded and converted into a Hardgrove Grindability Index (HGI) value; Typical resulting HGI values lie between 30 (increased resistance to pulverization) and 100 (more easily pulverized).
