The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (Wi). This index is determined on a laboratory scale using a Bond ballmill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained. This happens only after 7-10 grinding cycles, which shows that the procedure is a lengthy and complex one and

Work Index• Purpose : to estimate the crushability of a rock and the energyconsumption. Test also called Bond Work Index, or Impact Work Index.• Range of values :- 8 for very easy material- 28 for very hard material• Sample : 10 to 15 cubical stones of 50 to 75 mm, with 2 parallel faces.The stones must come from the run of quarry, not from crushing.•

Bond Work Index Procedure and Method This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process 1/2″ ore

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes.
