## 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

## Bond Work Index an overview ScienceDirect Topics

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

## Bond Work Index FormulaEquation

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## Services Offered by 1Metallurgy Capabilities

## Technical Information SMC Testing

BackgroundSample QuantityNumber of SamplesSize ScalingThe SMC Test® is a precision test that uses either crushed rock pieces that are very closely sized (socalled crush and select method) (Figure 4) or particles that are cut to similar size from drill core using a diamond saw (Figure 5) The latter approach (socalled cutcore method) is used when limited drill core sample is available Almost any drill core size is suitable, even core that has been quartered (slivered) The chosen particles are broken using a closely controlled range of impact energies The high degree o[PDF]## Bond EfficiencyGMGICEv1r04 Determining
