Standard Bond Ball Mill Grindability Test Method ProcedureInvestigation into the applicability of Bond Work Index

Here is the old Allis Chalmers Bond Work Index Grindability Test Procedure The standard feed is prepared by stage crushing to all passing a 6 mesh sieve but finer feed can be used when necessary It is screen analyzed and packed by shaking in a cc graduated cylinder and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load The mill is 12 in x 12 Oct 15 32 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 size •
