Bond Index Ball Mill / Rod Mill BT 100 XL RETSCH. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to mm whereas Ball Mill Work Index (BWI) is used for the range from mm down to 100 µm.
The Bond work index (Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger's law. Accordingly, the energy consumed in reducing the particle size from x F to …
Abstract The Bond work index, Wi, is defined in a Bond ball mill on the samples of standard size − 3.327 + 0 mm. In practice, it is possible to find materials of non-standard size that are finer than 3.327 mm. In this work, a procedure for the calculation of the Bond work index is suggested for cases when the Bond grindability test is conducted on samples of non-standard size.
Alternative Approaches for Determination of Bond Work, The Bond's work index of the above rock samples calculated from the Hardgrove index value has shown a variation from 77 to 103 kWh/sht A correlation is found between the friability value and work index The correlation coefficient of 093 between the friability value (S1) and Bond's work index, Wi = -18193 Ln (S1) + 66747 has been found
