Oct 15, 2015· 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. •
The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (W i).This index is determined on a laboratoryscale using a Bond ballmill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained.
grindability is Bond''s work index which is defined as the resistance of the material to grinding. The standard equation used by them for the ball mill work index (Bond work index) is as follows. 230. 82 1 10 / 80 > 10 / 80 1.
