18.104.22.168 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
internal mill diameter ‘Di’. By calculating the ratio ‘H/Di’ and using the graph below (Figure 1), the charge filling degree in volume could be estimated. The number of visible plates on the shell liner could also be counted and an angle could be calculated (α) but the accuracy of this method is far lower than the
Milling was carried out in a laboratory ball mill 312 284 mm (diameter length). The ball distribution was fixed at equal volume fraction of 15 and 23 mm balls. The mill speed was set on N c =71%. The concentrate was charged to the mill and rotated for a specific time, and then discharged. Five samples with different Blaine specific

Oct 26, 2017 Ball mill shape factors in the period prior to 1927 averaged 1.1/1 for 29 center discharge mills and 1.0/1 for 30 peripheral discharge mills. With the resumption of new plant construction after the 1930’s depression, the Morenci concentrator continued the 1/1 ratio with its 3.1 x 3.1 m (10 x 10 ft) mills.
size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was
