TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL

TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL DRIVES FOR GRINDING APPLICATIONS M. Ahrens, ABB, Switzerland,The concept to drive the mill this way is relatively simple using the mill body as motor rotor and mounting the poles there. As a result the motor does not have a separate (motor) rotor and thus no separate (motor) bearings. The number of poles is based on the required speedMV Drives, July 2012 ABB drives in cement Medium voltage,,control of bag house fan, raw mill fan, cement mill fan and preheater fan Benefits High reliability and availability Reduced maintenance costs High efficiency Wider range of speed control (from 0 to 1000 rpm) Network power factor >0.95 Chettinad’s cement plant in Karikkali, IndiaGearless mill drives - Grinding | 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.

ABB drives in cement Medium voltage drives for reduced,

Mills In cement production, mills are process critical. Reliable and precise control has a high impact on production throughput and operating costs. Controlling them with variable speed drives results in the following benefits. Optimized plant production By controlling a mill with a VSD, the speed of the millBall Mill Critical Speed - Mineral Processing &,A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical,Cement | ABB,Increase production and save energy. CO 2 emissions of the fuels used in cement production are a hot topic in the industry discussions, but more and more also energy efficiency is increasing its importance. The reason for this is that in addition to the improved profitability, authorities are beginning to steer industries towards more efficient processes.
