Assessing load in ball mill using instrumented grinding media ScienceDirect Abstract Introduction Section snippets References (43) Cited by (10) Minerals Engineering Volume 173, 1 November 2021, 107198 Assessing load in ball mill using instrumented grinding media Ting Wang a b, Wenjie Zou a, Ruijing Xu a, Huaibing Xu a, Le Tao a,
An evaluation of Relo grinding media (RGM, Reuleaux tetrahedronshaped 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.
