It is a measurement of how hard the rock is and an expression of the resistance that a material has to crusher. Shown in the table below is typical Work Index, reflecting the different rock characteristics.
The most widely used parameter to measure ore hardness is the Bond work index Wi. Calculations involving Bond’s work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (Wi C, CWi or IWi (impact work index)).Work Index, Work Index Efficiency, Bond Work Index testing 4.INTRODUCTION AND BACKGROUND The Bond method allows for quantification and com-parison of relative energy efficiencies of most industrial comminution circuits. It is an essential tool for managing the important business (cost) of grinding. For early analyses of plant grinding.
