grinding media on sag mill

Wear of grinding media in the mineral processing industry

Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding (SAG), rod milling, and conventional ball milling. Each of these mill environments presents a unique environment for grinding media, requiring the application of specific physical and chemical properties for optimum grinding media performance. The environments are

SINGLE STAGE SAG/AG MILLING DESIGN

Lack of grinding media in the S/AG mill will result in high circulating loads which can result in slurry pool formation due to grate and pulp lifter restrictions, further adversely affecting circuit performance. capacity is too high for a single SAG mill, a two stage grinding or alternate circuit is generally recommended. 4

Either by impacting of grinding balls on the rocks (SAG mill) or by interaction between rocks on the one side and mill shell and toe of the grinding charge on the other side (FAG mills). The trajectories of grinding media and rocks promote size reduction by im-pacts. This grinding mechanism is required in SAG and FAG mill applications. 2

Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising
