Oct 10, 2016018332Pipe ball mill Pic. 3 provided with a drive with construction similar to the drive of rolling mills. The central drive shaft has milled protrusions and depressions at the ends and enters them into the corresponding coupling. In this arrangement the axial displacement of the mill is not transmitted to the reducer or motor. i. 4.

SAG mills with a rated power of up to 35 MW. As well as ever larger SAG mills, ball mills are also expanding in size. In the late 1990s the trend moved towards using GMDs to power these larger ball mills, as well as using the drive to vary the speed. GMDs quickly moved from 20 ball mills, expanding to 24, 25 and then 26 mills.
