Ball mills are a fundamental part of the manufacturing industry in the USA as well as around the world. Ball mills crush material into various sizes and extract resources from mined materials. Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less.
Ball-Mill Base with Ventilated Motor-Cover Removed The Ball-Mill Drive System Looking inside the mill's motor compartment, you can now see the motor, with a small fan and pulley on its shaft. That small pulley is connected by a drive belt to a large pulley which is mounted on the unit's drive roller. The other roller is the idler roller which ...

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:

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 motor is usually fitted with a variable speed drive (VSD) to control the rpm of the ball mill. Gearbox – used for speed reduction from the motor to the ball mill. Balls – usually manufactured from manganese alloy steel, but the material depends upon for what material the mill will grind ( chrome steel alloy and rubber also available).
