Ringgeared mill drives Grinding ABB
We provide optimized mill drive solutions for all types of ringgeared mills: low and high speed, single and dual pinion, with and without a gearbox — all designed for reliable, long life and low maintenance operation Video explaining ABB ring geared mill drive technology Are you looking for support or purchase information?10/12/2012 To meet the high torque requirements of today's large ringgeared mills, low speed drives generally use synchronous motors The motors are usually rated in the range 35 to 9 MW and operate at a nominal speed of approximately 200 rpm Compared to the large 30 to 40 pole synchronous motors typically used in fixed speed drives, synchronous motors for variable speed operation have only 8 to Advantages of low speed drive solutions PACE7/2/2017 Logistic challenge: New stage goal The arrival of the low speed dualpinion mill drives for Collahuasi Copper Mine, ChileSiemens MiningindustrysThe arrival of Siemens low speed dualpinion mill drives
LOW SPEED ASYNCHRONOUS MOTORS FOR MILL APPLICATIONS
LOW SPEED ASYNCHRONOUS MOTORS FOR MILL APPLICATIONS V Matthews, Siemens Process Industries Drives, Alpharetta GA INTRODUCTION Typical grinding electrification requirements are defined by high power, constant torque and slow speed Dual pinion mills also include a need for tight tolerances in torque between the two motors, to avoidIn the world of mining and milling the “electrical term” LSSM stands for “Low Speed Synchronous Motor” and usually means a mill where the motor rated speed is in the range of 10 RPM, the same speed as the mill turns A high speed motor can run at 900 RPM and uses a gearbox to turn down the speed A medium speed motor runs in the range of 100 RPM and uses the gear ratio of the pinion LSSM = Low Speed Synchronous Motor Drive Operationof faults in gearless and lowspeed gear drives such as SAG (semiautogenous grinding) mills and HPGR (high pressure grinding rolls) drives It combines traditional condition monitoring reporting with a continuous, automated online monitoring system that provides timely alerts and fault analysis The reporting system is highly customisable, including options for both cloudbased and localised ONLINE MONITORING SYSTEM FOR GEARLESS AND LOWSPEED
