Method of preparing grinding media consisting

However, the process used to produce such grinding media is cost-intensive, since it involves making spherical particles from a physical mixture of titania, alumina, and silica. Further, these grinding media have a relatively high weight percentage of alumina which contributes to their having generally good wear-resistance properties.

Sino Grinding Mineral Processing

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 dryer. Mill operators optimize the pattern within the mill to ensure grinding media
