Mill grinding Wikipedia

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 There are several advantages to the tower mill low

Energy Use of Fine Grinding in Mineral Processing

· Millpebs have been used as grinding media to achieve fine grinding in ball mills These are 5 to 12 mm spherical or oblong cast steel pellets charged into ball mills as a replacement of or in addition to balls While Millpebs can give significantly lower energy use when grinding to finer sizes they also can lead to high fines production and high media use Millpebs were tested for fine
