Mill Steel Charge Volume Calculation. Mar 19, 2017 We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill
· 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 ...
