Grupo Mexico will use GE''s advanced synchronous motor technology to add 84 megawatts (MW) of power at six Buenavista ball mills. Quadramatic motors run at fixed speeds with minimum system losses to promote high efficiency, thus lowering the mine''s energy requirements.
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
Ball Mill Cyclone Iron Ore Iron Ore Process Roller Press More efficient process compared to Ball Mill crushers. Energy savings of 10 to 30% compared to ball mills Reasons to use VFD with Roller Press Using variable speed motors it is possible to adjust system demand for upstream and downstream process. VFD allows higher efficiency and
Efficiency after reconstruction. The Chinaware ball mill can realize automatic control and can switch between the variable speed drive and mains supply. Through the VFD drive''s automatic voltage adjustment function, the motor can achieve its highest efficiency. Starting current is only 1/5 of the previous, realizing soft start.

When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pullin torque, and 225% pullout torque. These assume no greater than a 10% voltage drop at the motor terminals. VBELT Ball Mill DRIVE Vbelt or polyV drives are generally used on grinding mills consuming 350 HP or less.
These ball mills are relatively small, bearing mounted on a steel frame. All ball mills are sold with motor, gears, steel liners and optional grinding media charge/load. Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be ...
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ringgear, 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.
