• Bond Work Index - an overview ScienceDirect Topics

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. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

• Bond Work Index Formula-Equation

Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack EnergyThe basic work index equation is:W = 10 Wi/√P – 10 Wi/√F(1)where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the work index, or the grinding resistance parameter. It represents the energy input required in kilowatt hours to reduce a short ton from theoret在911metallurgist上查看更多信息

• Determination of Work Index of Gyel-Bukuru Columbite

2015-5-27  The most widely used parameter to measure ore grindability is the Bond work index, W i [6]. Work index is the energy required in kWh/short-ton to reduce a given material from theoretically infinite size to 80% passing size, 100 microns [7]. The determination of work index using Bond’s method can be compared to the method of
