The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 12.7 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 0.305m by 0.610m, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.

Testwork: Bond abrasion index  SAGMILLING.COM
The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off the test coupon).

Bond Work Index  an overview  ScienceDirect
The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining the rod mill work index (Wi R or RWi).

Geometallurgy  Wikipedia
Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design. It is also used, to a lesser extent, for

Mineral Comminution fine / ultrafine grinding

Essa® Bond TestWork Equipment – Mineral Stats
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 F.C.Bond in the mid 1930's.

Bond Work Index Rod Mill  Titan Process
The Titan Bond Work Index Rod Mill is onepiece cast construction with integral wave liners of a form described by Bond. This mill is used to perform the necessary metallurgical testing to determine the grinding characteristics of ores and power requirements for operating productionsize rod mills.

Rod mills, how they function  Mine Engineer.Com
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
