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.

Abstract. Stirred mills were first introduced in the 1950`s as an alternative to ball mills in a regrind application. Since then they have been used to grind a range of materials from limestone to coal to sulfide concentrates. A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill.
