An evaluation of Relo grinding media (RGM, Reuleaux tetrahedron-shaped bodies) performance versus standard grinding media (balls) was made through a series of grinding tests, including a slight modification of the standard Bond test procedure. Standard Bond tests showed a reduction in the Bond ball mill work index (wi) of the mineral sample used in this study when using Relo grinding media.

A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.

Similarly, in ball mills, it is known that grinding finer than approximately 40 μm will result in overgrinding of fines as well as high media consumption. However, it must be noted that the product size to which a mill can efficiently grind depends on the feed material, the F80, and media type and size.

Ball Mill Media (kg/kWh) = 0.0944*Ai^0.299. Aidan Giblet and J. Seidel published a paper on the 2011 SAG conference (MEASURING, PREDICTING AND MANAGING GRINDING MEDIA WEAR) and they obtained. Ball Mill Media (kg/kWh) = 0.0817x(Ai)0.498. the two equations are very similar.
