More DetailsWithin 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.
More Details2011-6-28tative sample for size distribution is easy to achieve for fine particles and challenging for coarse particles. This is due to the numbers of particles issue, with there being too few large particles to give a representative sample for a manageable sample size. For AGSAG feed, good access to 1020 m of the feed conveyor is essential.
