GRINDING MILLS. United States Patent 3739993. Abstract: An autogenous grinding mill of large diameter has curved lifters to give improved radially inward displacement of reduced material, after passage through the primary grates; and secondary grates in the form of box sections combined with the curved surfaces of the lifters, for segregation ...

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.
