3. Ball mill reducer bearing heating: In addition to take the inspection of ball mill bearing temperature rise, we should check whether the reducer vent is blocked, to dredge the vent. 4. After the ball mill motor starts with the reducer, it vibrates. The main reason is that the bearing outer ring is active.

The ball mill machine cannot be started or the motor is overloaded when starting. Reasons: there are problems in the motor system, there are obstacles in the rotating part, the materials and grinding medium in the continuous ball mill are not removed in time after a long time of shutdown, which makes the wet materials condense into agglomerates.

Solution of a Serious Repetitive Vibration Problem on a 4500-hp Single-Pinion Synchronous Motor Ball Mill Drive Abstract: Vibration problems which occur after some considerable period of operation are often solved by simply replacing or repairing worm system components.

Torsional vibration in ball mills can be a serious problem -even leading to failure. In the design of such mills it is therefore important to be able to design them so that such vibration will not be a problem. It is thus desirable to be able to model the torsional vibration of a rotating system which includes a ball mill.
