Ring Type Synchronous Motor of double winding, fed by two Three–Phased Cycloconverters. The rotor has salient poles without dumping windings and it consists of 72 poles. The cycloconverters work in the out-of-circulation current mode and they are connected to a 13.6 MVA transformer.Modeling and Evaluation of Cycloconverter-Fed Two-Stator,,This paper presents and evaluates three different modeling options for the SAG mill drive and considers the equivalent one-stator synchronous motor fed by an ideal converter that produces purely sinusoidal voltage and current waveforms. Typical drive configurations of high-capacity SAG mills use a two-stator-winding vector-controlled synchronous motor, with a 30° shift
Difference Between Sag Mill vs Ball Mill - mech4study
12-10-2017· 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.SIMINE Gearless mill drives - assets.new.siemens,stator axis 7. Sophisticated design –, Whether you’re talking about SAG or a ball mill, space is a delicate issue, especially in the concentrator. That’s why we always design our Gearless mill drives drives to combine maximum performance with limited space requirements.The Siemens 42ft gearless mill drive, still an,,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.(PDF) Evaluation of synchronous motors on grinding mills,The subject of this paper is a synchronous drive of grinding ball mills 4 MW, 150 rpm, 6 kV, 50 Hz on the base of PWM CSI.

Making remote mines and low ore grades economical and,
Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, round-the-clock reliability and the opportunity to mine in remote areas. This makes low ore grades economical to grind.TMdrive -10SPR Product Application Guide,Slip Power Recovery Drive System for a grinding mill SAG Mill and Motor The Best Solution: TMdrive-10SPR for each pump • The SPR drive carrying slip power is much smaller and less expensive than an MV drive carrying all the motor power at full speed (4 kV voltage) • The SPR drive has a smaller footprint than a large stator supply drive,,,,
