    Bond Rod Mill Grindability Test. Grinding Solutions can carry out Bond Rod Mill Work Index tests to determine the energy requirements for milling ore in a rod mill. The test requires a minimum of 20kg of -12.5mm material. Closing screen sizes typically range from 4.75mm to 212µm. Abrasion Index Test

  • Bond Work Index Formula-Equation

    Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack EnergyThe basic index equation is:W = 10 Wi/√P – 10 Wi/√F(1)where W is the input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the 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

    Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.
