Elastic mill sag by weight of mill balls and materia! to grind A: After temporary alignment of the teeth of pinion and girth gear with the mill empty, Fig. 8a, realignment should be undertaken with the mill filled with mill balls, i. e. with reference to the elastic sag in cold con dition, Fig. 8b.
Because of an impact when a bar enters the mill, the pinion "bounces" within the gear tooth space, causing high dynamic tooth loads. Raymond J. Drago is chief engineer of Drive Systems
Brochure QdX4 Mill Drive system. SAG mill 32 ft. single drive. The natural progression in gear/pinion mill drives: The QdX4TM Mill Drive provides the next step in the evolution of change in internal torque splitting capability transmitting motor input power to the pinion shaft and equally dividing into two mill
Ball mill speed can be reduced during short maintenance measures, e.g. inspections of the SAG mill. This avoids fixed speed pinion drives have to be stopped with a prior grindingout / drainout process before interruption and the necessary time to restart. As a consequence, variablespeed capability helps the operator to reduce downtime.

The following five drives systems are to be studied: •. Drive 1 A 5000 HP, 1200 rpm wound rotor motor with liquid rheostat and power factor correction capacitors to a dual pinion gear driven mill. •. Drive 2 A 5000 HP, WEG Provides Innovation in Ball Mill and SAG Drives with Dual . WEG Provides Innovation in Ball Mill and SAG Drives with
SAG Mill Components Manufacturing limitations from gear vendors determine the minimum number of pinions which can be used to drive the mill as well as the number of gear sections. If the advantages of a synchronous motor are desired on any dual pinion drive appliion, dual synchronous motors are available to drive dual pinion gear
The Ernest Henry SAG mill. (11 MW) is currently the largest twin pinion single drive mill installed in Australia. Problems have been experienced with the twin pinion drive at . Single pinion drive Appliions Flender. Flexible and Precise Gear Units for Optimum Tooth Mesh.
Overview on the grinding mills and their dual pinion mill drives The grinding process with one 34'' x 20'' SAG mill and two 24'' x 39.5'' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion
Sag Mill Syncronis Motor high axial vibration non drive end Nov 1, 2014 On site we have a Sag Mill Driven by a 5500KW Motor. Is the vibration coming from the motor and going to the pinion
Some consultants have the view that the gear drive is limited in power. Mr Craig Denecki (Falk Milwaukee) in his paper, presented at the 1996 SAG mill conference, provided details of the then largest gear drive in operation on a SAG mill (34ft x 18ft) at Escondida 13.4MW, which began operation in 1995. The reason for not having larger gear drives
Mill Pinion Gears. Our high torque, high precision integral and nonintegral mill pinions are used in SAG, horizontal ball mill and rotary kiln appliions across the globe. Supplied as an individual component or as a fully optimised system comprising a girth gear, mill drive gearbox, pinion and barring drive, our pinions are manufactured
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.
A SAG mill requirement might be 225250% torque based on Full Load Motor Torque (FLMT). This is the amount of torque the drive motor can produce on a temporary basis during start up. Wichita Clutch has designed its multiplate Grinding Mill Clutch (GMC) specifically for use on challenging ball and SAG mill

GROSS POWER CALCULATOR General measured at the shaft which drives the pinion gear in a gearandpinion drive. Apart from in pilotscale mills, the power at pinion is never directly measured in full scale operating mills but is estimated from the power draw of an AG/SAG mill to drop can be gauged by switching the discharge mechanism
Based on ABB''s 800xA platform, the RMDcockpit is a specific mill appliion tool comprised of a touch screen panel allowing full access to the main parameters of the drive system as well as to the mill appliion features such as automatic positioning and creeping modes.

Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive.
