A centrifugal ball mill wherein means are provided for actuating the planetary rotational movement and separate means for actuating the rotational movement of the mill barrel about its axis of rotation. The axis of the milling vessel can be parallel with the axis of the rotation of the planetary movement or perpendicular thereto. When the axis of rotation of the milling vessel is …
Induction Motors [2]. Figure 3 shows a ball mill with a dual pinion drive 2x 6500 kW with low speed induction motors (LSIM). The dual pinion drives demand tight tolerances in the torque between the two motors [2] to dynamically equalize the load on both pinions so that, in the long run, their duration is secured and the system availability
Torque is the measure of how much immediate rotational force a spindle drive motor can generate. Many times when machinists look at cutting tool speeds and feeds, they are often misled into believing that they should be concerned with horsepower. The real driving force is not horsepower, it's TORQUE.

The Ball mill operated in closed circuit with several vibrating screens, with the circuit designed to treat 1875tph of Uranium ore delivering a product of P80-350um. Both the SAG Mill and the Ball Mill were supplied as dual drive mills carrying full VSD capability, through supply of two ACS6000 VVVF Drives.
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.
Maintenance practices and recommendations to maintain the reliability of machinery. Prevention of unnecessary downtime and production losses.
Mill application features. Frozen charge protection – Detects frozen charge in the mill, minimizing equipment wear and liner replacements.; Coupling supervision – Detects if a failure or slippage occurs in the couplings and stops the system in case, preventing major damages.; Stand-still detection – Prevents the motors from re-starting if the mill is still rocking or moving after a …

High vibration on the ball mill drive train A and B. 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.
The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. 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'.
SER drives are now mature and ready for use on 2 X 10MW dual drive mills. Speed variation required is in the range of +/- 15% of synchronous motor speeds. VVVF drive packages from ABB and Siemens are also available for 2 x 10MW in low and high speed options. Dual hydraulic inching drives provide a much safer and
Mill speed is varied by changing the frequency of the current to the motor, allowing adjustments to the mill power draw as ore grindability changes. The gearless drive design was not applied to the mills in the mineral industry until 1981 when the then-world's largest ball mill, 6.5 m diameter and 9.65 m long driven by a 8.1 MW motor, was ...

According to Figure 1, the dynamic model of the ball mill is where is the rotation resistance coefficient of the drive motor, is the friction torque, and the rotation direction of the ball mill is determined by the sign function sign().. When the rotational speeds of the clutch are synchronised, i.e., =, the clutch no longer slips. The dynamic model can be written as follows:
