รายละเอียดเพิ่มเติมThe Bond rod-mill work index is used in conjunction with Bond's third theory of comminution to merely calculate net energy requirements for sizing rod-mills. This test was originally developed in the mid 1930s by F.C. Bond. Though, it was altered in succeeding years, it has essentially remained unchanged since 1961 [1].
รายละเอียดเพิ่มเติมCommentary on the apparatus of the Bond rod mill work index The Bond "Third Theory" of comminution was originally divided into three size classes reflecting the varieties of comminution equipment common during the time period when Bond (and his collaborators) were gathering the information to calibrate comminution models.
รายละเอียดเพิ่มเติมThe 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. The test is a closed-circuit dry grindability test performed in a standard rod mill.
