## 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 Mehr zu 911metallurgist anzeigenGeschätzte Lesezeit: 10 min## What Is Bond Ball Mill Work Index labornrwde

A bond ball mill work index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits sample requirements a minimum of 8 kg of material crushed to nominally minus 10 mm is preferred jktech would stage crush the sample to minus 335 mm as required for the bond ball mill work index test Look more > Look more > inquiry > inquiry >

## Bond Work Index an overview ScienceDirect Topics

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5 ) Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 )

## Correction of Bond Ball Mill Work Index Test for Closing

07122018 It is commonly known that one must run the Bond ball mill work index test such you pick a closing mesh to give a P80 close to desired grind size This is because work index frequently changes as a function of the product size in comminution If target grind size during a project is changed, or if
