How to deal with the vibration of coal mill vertical

vibration vertical roller mill Page 1 of 2 International . re vibration vertical roller mill. There are a number of reasons for high vibrations in vertical roller mills, such as: 1. Failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete.

High vibrations on a ball mill AMP Maintenance

21-01-2011  Now, when the mill is started, vibration values are around 14 mm/s, first 4 harmonics of the GM, and then for about half an hour they go up to 28 mm/s (again 4 harmonics of GM) - in horizontal direction while in the vertical and axial direction there is no such change.

An Experimental Investigation into Torsional Vibration in ...

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.
