Advantages of Ball Mills. 1. It produces very fine powder (particle size less than or equal to 10 microns). 2. It is suitable for milling toxic materials since it can be used in a completely enclosed form. 3. Has a wide application. 4. It can be used for continuous operation.
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 400mm sometimes even larger and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 4000 while the ball mill s
Its also possible to note in figure 7 that k from vertical mill decreased along the year even reaching smaller values than those for ball mills in some points. This is due the wear of cyclones apexes and consequently the increase on vertical mill circulating load which reached values over 500 by the end of the year.
