(PDF) Evaluation of synchronous motors on grinding mills

Synchronous motors continue to be a viable alternative to induction motors because of efficiency advantages. Long used for providing leading kVARs for PF improvement and helping with the device...

SAG Mill Components - Mineral Processing & Metallurgy

A cyclo-converter reduces the power frequency and a synchronous motor is either wrapped around shell or mounted on a trunnion extension. This makes the mill essentially a part of a synchronous.motor rotor with the stator in its usual position around the rotor. Inherent in this type of drive is limited speed variation.

motors of sag mill -

For SAG 2, Siemens supplies two 8 pole, high speed induction motors to replace the existing slip-ring motors, eliminating all brush or slip-ring related outages and maintenance activities. The four identical variable speed drives (VSD) operating all four mill motors are Sinamics Perfect Harmony GH180 units.

Ring gear drives huge grinding mill | Machine Design

SAG mills can operate at a fixed speed or adjustable speed through the use of ac synchronous motors or dc motors. They typically range up to 16,000-hp. A secondary, or ball mill, works a lot like a...

On site we have a Sag Mill Driven by a 5500KW Motor. We have a vibration issue right across the Mill. The highest vibration is 30mm/sec RMS axial on the motor non drive end bearing.(White metal Bearing) The gear mesh frequency is 4200 CPM. The dominant frequency is 2400 CPM.

synchronous motor specficications which used for ball mills

Synchronous Motors - Drive Technology - Siemens. Our rugged high voltage IEC synchronous motors are used in a wide variety of applications, which call for the highest power and torques capabilities, as well as a maximum plant availability In applications such as central gas compressor stations, blast furnaces, rolling mills or ore mills.

Teco-Westinghouse Custom Synchronous Motors

Synchronous machines can be found wherever there is a demand for highly efficient, cost-effective, dependable machines. They are frequently used for rolling, ball and sag mills, chippers, mixers, pulp refiners, pumps, fans, and compressor (reprocating and centrifical) drives.

Advantages of SER drives for SAG mills |

So at say 85% speed, 15% of the motor rated power is returned from the rotor to the supply. At a hyper-synchronous speed, the SER drive feeds power into the motor rotor allowing it to run faster than synchronous speed. So for a fixed torque and higher speed, the power obtained from the motor is higher than the motor nameplate rating.

Autogenous and Semi-Autogenous Mills | FLSmidth

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

Blecher Motoren GmbH is among the leading motor suppliers in Germany. With a stock of over 10.000 motors, we own one of the largest motor parks of Hesse and our motors are used for applications in various industries: Wind turbine


he gearless motor (also called wrap- around motor or ring motor) is a very large synchronous motor. The poles of the motor are directly installed on a pole flange on the mill shell: this means the mill body becomes the rotor. The stator of the gearless motor is then wrapped around the mill.

Mining - Grinding and Processing | WEG

Designed to drive and control the speed of the medium voltage motors coupled to the SAG/AG, ball and HPGR mills with single or double pinion, the MVW01 frequency drive uses state of the art technology through a multilevel structure with medium voltage IGBTs, reducing the harmonic currents on the motor to extremely low levels.
