· Millpebs have been used as grinding media to achieve fine grinding in ball mills. These are 5 to 12mm 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 ...
