1. Introduction The Bond rodmill work index is used in conjunction with Bonds third theory of comminution to merely calculate net energy requirements for sizing rodmills. This test was originally developed in the mid 1930s by Bond. Though it was altered in succeeding years it has essentially remained unchanged since 1961 1 .

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements when siing ball mills. Various correction factors may have to be applied. The test is a closedcircuit dry grindability test performed in a standard rod mill. Get price
Essa® Bond TestWork Equipment. Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index and the Bond rod mill work index. These are empirical indices determined by close circuit grindability tests developed by in the mid 1930 s.

The Bond rod mill work index is not as common as the Bond ball mill work index and there are two different variations on the mill apparatus. The models expect a mill with a "wave liner" and is not compatible with mills using "smooth liners". Most laboratories outside of Australia use the wave liner style of machine these
