Rapid determination of Bond rod-mill work index by ...

2013-1-1  The 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.
