Gearless motor drives are also known as ring motors or wrap around motors. The motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill. This is similar to the rotor of a conventional motor.
We will begin with the mills bull gear assembly and work towards the motor, The BULL GEAR, sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill. By mill we refer to Ball Mills, Rod Mills and SAG Mills. Anything gear and pinion really. The discharge end of the mill; For the operator this only becomes a problem should the
Ring gear drives huge grinding mill Machine On the outside, horizontal grinding mills often face the elements. SKF solutions help drive grinding mill reliability and safety while reducing maintenance and Today Polysius grinding mills are exclusively built as shellsupported units.

mill and two 24'' x '' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. Copper Mountain has installed on all three mills, the new stateofthe art dual pinion mill drives. All the inherent operation and maintenance features of this
Grinding Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semiautogenous. The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles.
Traditional ringgeared mill drives have a ringshaped gear that encircles the mill and drives it through one or two pinions followed by conventional motors. GMDs mount rotor poles directly to the mill body and surround it with the stator ring, incorporating the mill itself into the motor.
A crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached. It is a mechanical part able to perform a conversion between reciprocating motion and rotational a reciprocating engine, it translates reciprocating motion of the piston into rotational motion, whereas in a reciprocating
Girth gear drive provide optimum performance as mechanical systems for reducing motor speed to working speed of mill As an important component in gear drive assembly, these can be offered in multiple segments including 2, 4 or 8 equal sizes
The userfriendly LM201 can be fitted with 800, 1000 or 2000 cc single disctype grinding bowls, and the standard size ringandroller grinding bowls. It typically grinds

answered. 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 gearbox
As Figure 2 shows, the gears are huge. Pinions range from 2 to 4ft pitch diameter and 4 to 10 ft long. Usually, all gear drives (and supporting bearings) in a mill are lubricated by a common
