Shell supported ball mills are ideal for the use of ring motor drives: 3 Because of the high rigidity of the mill shell, troublefree transmission of the magnetic forces is assured. 3 Due to the individual self-adjustment of the sliding shoes, the pole pads attached to the mill shell can be centered in the stator of the ring motor.

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
not an option for a 42ft Gearless Mill Drive. The ring motor is not self-supported and needs the mill to fix the rotor poles to and it needs the mill foundation to support the stator. Finally you would need a few thousand tons of ore and possibly even an earthquake would be needed to have a realistic test environment representative of a mine site.
Sag Mill Motor Complete Stator. sag mill motor complete stator. Gearless mill drivesGrinding ABB. Our GMD eliminates all mechanical components of a conventional mill drive system such as ring-gear pinion gearbox coupling motor shaft and motor bearings By mounting the rotor poles directly onto the mill the mill itself becomes the rotor of the gearless motor.
