SmartMill Grinding ABB
Combine ABB's variable-speed drive system with advanced process control ABB Ability™ Expert Optimizer for grinding to provide maximum mill control. It can be applied to new or existing AG, SAG and ball mills, powered by either ring-geared mill drives (RMD) or gearless mill drives (GMD). This solution was designed to control, stabilize andanswered. Depending on the mill size and type, the mill can be driven by several configurations of drive systems. The main options are single low speed motors connected to a pinion driving a ring gear, two low speed motors connected to two pinions and driving a ring gear, or a gearless motor mounted directly onto the mill. In addition, a TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS

Making remote mines and low ore grades economical and ABB
ABB GMDs use a high efficiency cycloconverter to drive the motor. The same efficiency applies to other system components like transformers and the motor control centres incorporated into ABB’s E-house solution called Control Block; together, these advancements can boost energy optimization in grinding mills by as much as 3%.SAG mill and two 26 ft ball mills, all made by TON. The drive systems that enable the mills to operate at benchmark levels of reliability, efficiency and availability were made by ABB, whose solution comprises a 23.5 MW gearless mill drive (GMD) for the SAG mill, and two 13 MW low-speed dual-pinion ring-geared mill drive (RMD) systems Mount Milligan mill drives ABB

Long Term Motor Storage Procedure ABB
5. Motors with anti--friction bearings are to be greased at the time of going into extended storage with periodic service as follows: a. Motors marked “Do Not Lubricate” on the nameplate do not need to be greased before or during storage. b. Ball and roller bearing (anti--friction) motor shafts are to be rotated manually and greased in2.1 Deep Groove Ball Bearings These ball bearings are the most common type of bearing. These bearings can handle both radial and thrust loads. Due to their low frictional torque, they are suitable for high speeds. In a ball bearing, the load is transmitted from the outer race to the Ball and from the ball to the inner race.Motor Bearings, Not Just a Piece of Metal ABB

gearless motor. Building a track record ABB's experience in optimizing gearless solutions for grinding applications extends over 50 years, making it the market leader with the largest number of installed units worldwide. In 1969, ABB commissioned the first GMD for a ball mill at Ciments Lambert-Lafarge, France. TheABB mill drive is very network friendly. Motor torque Motor speed Network current Figure 5. Calculated network current during start/stop sequence. Operation Area As soon as the cascading of load has been detected and the mill runs stable, the mill controller releases the drive to ramp up to the customer speed reference received from DCS.SOPHISTICATED RING GEARED MILL DRIVES: FEATURES
