Using the Benshaw Low Voltage Drive for positioning a MV synchronous motor driven ball mill is another great solution. The Benshaw variable frequency drive powers the 4160v synchronous ball mill motor during positioning to smoothly rotate the ball mill, providing full torque at zero speed to start and rotate the mill during the positioning process.

Motor The GMD is a drive system without any gear where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. The concept to drive the mill this way is relatively simple using the mill body as motor rotor and mounting the poles there.

Analysis of Variant Ball Mill Drive Systems. The basic element of a ball mill is the drum, in which the milling process takes place ( Figure 1 ). The length of the drum in the analyzed mill (without the lining) is m, and the internal diameter is m. The mass of the drum without the grinding media is 84 Mg.

Energy savings may also be found in the ball mill drive systems. In the scale of a processing plant, the electric motors of these drive systems account for 95% of the total electric energy demand [23]. Therefore, the type of the motor used has a significant influence on the efficiency of the drive system. One of the solutions aimed at improving

The main motor is connected to one side of the gear unit, while the auxiliary drive is connected to the other side. The pinion at the mill's girth gear can be connected via a doublejointed coupling with spacer to ensure the adjustability of the pinion. Single pinion drives are supplied in both fixed and selfaligning design.
