What is the difference between a SAG mill and ball mill
Like ball mills grinding steel balls or pebbles are often added to stirred mills to help grind ore however these mills contain a large screw mounted vertically to lift and grind material In tower mills there is no cascading action as in standard grinding mills Stirred mills are also common for mixing quicklime CaO into a lime slurry.

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.
