Jun 17, 2020 Two fundamentally different philosophies exist to drive horizonal mills While the gear unit and the electric motor of a central drive are located at the front of the mill and take up a lot of space, the lateral drive is placed at the side of the mill. The three-stage spur gear unit includes a mechanical torque split and contributes significantly to the extremely compact setup.

Relatively small slowly varying shaft position and velocity variations superimposed on the normal running speed of dual drive grinding mill motors can cause individual motor torque variations which disturb load sharing. The magnitude of load or torque unbalance is a function of the magnitude of the mechanical variation, the type of motors used, i.e., induction or synchronous, the number of ...
Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.

The following shows how the size or select the matching mill required to draw this power is calculated from known tables the old fashion way.
Aug 25, 2016 We are experiencing high vibration on our dual drive ball mill. The high vibration is on the motor DE bearing on axial direction. Dominant frequency is girth and pinion gear mesh. See attached spectrums and trends. Gearbox hold-down bolts are breaking due to high vibration.
2 GEARLESS MILL DES The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record
