Author PowderScience Read MoreTorsional 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.
