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.

Analysis and validation of a runofmine ore grinding mill circuit ...

Two types of mills commonly found in the minerals processing industry are ball and semiautogenous (SAG) mills, which use both ore and steel balls as grinding media (Wei and Craig, 2009b).In the case of a ball mill the ore is crushed before it enters the mill, whereas a SAG mill receives runofmine (ROM) ore directly (Stanley, 1987).A SAG mill in a singlestage closed circuit configuration ...
