Using stirred media mills in ore grinding - Technologie ...

In stirred media milling, a smaller grinding media size compared to a conventional ball mill makes high-speed movement possible, thus higher force on the ore particles trapped in media is applied. This is significant since as the particle size becomes smaller, the force needed to break the particles increases.
