This Grindability Test orBond Ball MillWorkIndex Procedureis used to determine theBondWorkIndexof minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in aBall Millusing a standardballcharge. Below describes in general terms theBondWorkIndex Procedureused by a Professional Metallurgical Testing Laboratory.[email protected]

TheBond Ball MillWorkIndexis a measure of the resistance of the material to grinding in aball mill. It can be used to determine the grinding power required for a given throughput of material underball millgrinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.Get Price
