  • Using stirred media mills in ore grindingTechnologie

    May 24 2021  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.
