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 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

ABB: a 28 MW GMD for a 40' SAG mill and two 22 MW GMDs for 28' ball mills, to be installed at the highest altitude ever of 4600 meters above sea level. In addition, ABB has also delivered a 28 MW GMD for the world's first 42' SAG mill and is well positioned to continue the push for larger and more powerful mills.
For coarse and hard materials, larger steel balls should be selected, for fine and brittle materials, with smaller diameter steel balls, the impact times of steel balls in the mill increase with the decrease of ball diameter, and the grinding between balls increases. The clearance is dense with a decrease of spherical diameter.
compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant. Moreover, as this paper seeks to demon-

Use a 1,190 µm screen to close the rod mill Wi test for these purposes. Choose a closing screen for the ball mill test that is one (standard square root of 2 series) mesh size coarser than the plant ball mill circuit P80. If choos-ing between two standard mesh sizes, choose the finer one.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".
