Unlike imbalance, misalignment does not produce forces that are similar in the radius of the machine. Vibration in one radial direction may be very different in amplitude when compared to vibration in another radial direction. This is one instance where amplitude readings are not only helpful in detecting a problem but also helpful in diagnosing a problem.

It makes the material loose with the vibration of the motor, so that it can eliminate the material arching camber, blocking, attaching problems. Working principle: With the Motor power on, it will form an inertial exciting force, so that the spherical activates to produce a strong horizontal vibration
Ball mills are predominantly used machines for grinding in the cement industry. Tube mill with precrushing unit vertical shaft impactor (VSI) or horizontal impact crusher production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific

motor vibration problems on a tube ball mill. Development of a Tubeball Coal Mill Mathematical Model Using, optimization problems with a faster convergence rate than, The Tube Ball mill used by EDF is a motor driven tumbling barrel charged, Figure 1 Tube Ball Mill Principle of Operation, outlet temperature vibrates away from the measured mill,
A good routine vibration program using a portable data collector, or permanent online vibration monitoring, will become the foundation of any predictive maintenance initiative. Measuring, trending, alarming and analyzing fan and motor vibration will provide earlier warning of developing problems and allow replacement parts to be ordered.

As such you will find it is designed and constructed according to heavy duty specifications. It is designed along sound engineering principles
rotating system which includes a ball mill. The major difficulty with modelling torsional vibration is the low level of damping in rotating systems and insufficient information about its magnitude. This paper describes an experimental investigation of the torsional vibration of a ball mill with a particular emphasis on the damping of the mill itself.

Choosing vibration monitoring methods These mills are characterized by their large diameter and short length, as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore monitoring of this type of equipment is crucial for modern mining operations.

levels of vibration are indications of condition except where structural resonances (: bearing housings, or motor bases) amplify vibrations at certain frequencies (usually integer multiples of shaft speed). Dynamic response at vibration test points can be measured on new installations to assist in establishing standards for absolute vibrations.
However, vibration can also be a result of an underlying issue with the motor, such as loose bearings, misalignment, or corrosion. Possible Solution: Motors should be checked regularly for vibration, using a motor analysing tool such as the SKF EXP4000 Dynamic Motor Analyser. In order to reduce vibration
