• fred bond ball mill power draw equations

    The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments. Although, Bonds method has been widely used, the required link to classifiion is missing. Bond Work Index FormulaEquationThe basic work index equation is:W = 10 Wi/P 10 Wi/F(1)where W is the work

    For small ball mills, the power draw under dry batch grinding conditions was derived by Austin et al. [5] and the same considerations apply for rod mills. Equation () indies that like any tubular mill the variation of mill power with speed in a rod mill is almost linear. This is true at the initial stages but breaks down when the critical ...

  • Size Reduction and Energy Requirement

     · This equation reverts to the Bond equation (Equation ) by taking the value of B as 12 and integrating; thus, () E = k 1 P 6 12 − 1 F 6 12 which in effect is the Bond equation. Bond's original work on establishing the energy for size reduction was established in a m (8 foot) internal diameter wet grinding overflow type ball mill.
