  • Bond Work Index Tests Grinding Solutions Ltd

    The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a predefined media and ore charge The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits The test requires a minimum of 10kg of sample that has been stagecrushed to 100% passing size of <335 mm

    The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

    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 theoret1metallurgist
