    Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills also known as primary mills where grinding media is released like hammers to assist in the ore cracking / grinding process. The mix of media and ore rises and falls in the mill like clothes in a The OED Mill has been designed to maximize slurry transport and minimize slurry pooling. This increases throughput capacity and improves grinding efficiency due to increased impact energy. Slurry pooling minimization in the OED Mill is facilitated by a novel grate-supporting spider.
