Chemical Engineering, Vol 6., Nos 6 and 8). A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant. Where possible, it is carried out on a sample of ore.
While grinding, the mill repeats a tilting cycle during the 100 revolutions. It runs level for 8 revolutions, then tilts up five degrees for one revolution, then down at five degrees for one revolution, and then returns to level, and the cycle is repeated. *Bond, F.C. 1961. “Crushing and Grinding Calculations Part I and II”, British.

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 pre-densified particles close to the target.
