The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is by, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.
Rod tangling is a problem that should be avoided by using straight rods. Rods < 6 meters are generally never straight. Rods should be 152mm shorter than mill length. Rod life is maximized of rod lengthtomill diameter is maintained between to Rods wear unequally with thin rod formed at the feed end and forming an elliptical shape.
Bond Rod Mill Grindability Test. Grinding Solutions can carry out Bond Rod Mill Work Index tests to determine the energy requirements for milling ore in a rod mill. The test requires a minimum of 20kg of material. Closing screen sizes typically range from to 212µm. Abrasion Index Test
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 models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners".

Commentary on the apparatus of the Bond rod mill Work Index by Alex Doll December, 2015 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. The middle .
The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.
