  • determination of the bond work index on samples

    · the bond work index, w i, 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.
