Test data from the Bond ball mill work index test is used to calculate the fine grinding index (M ib). The M ia and M ib indices are used to calculate specific energy for the coarse (W a) and fine (W b) components of the total grinding specific energy at the pinion (W T) according to Equation 7. W i = 4.K.M i.[Pf(P)-Ff(F)] (6) W

* Bond F. C., "Crushing Tests by Pressure and Impact", Trans AIME, Vol 169, 1947, pp 58-66. 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.

### Procedure for determination of ball Bond work

The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling. The values obtained by this procedure do not differ by more than 7% from those obtained in the standard Bond test.
