  • A procedure for rapid determination of the Bond work index

    01-09-1989 · The Bond work index has been widely used in designing full-scale mills but the Bond test is rather complex lengthy and susceptible to procedural errors and this is why attempts have been made to abbreviate and simplify Bond's test procedure. Smith and Lee (1968) compared Bond grindability with straight batch-type grindability.
