  • Grinding Media Oscillation Effect On

    tumble mills are hollow cylindrical shells of large diameter carrying grinding media which, upon rotation of the mill, will be ground into fine powder. these mills rotate at low speeds using a gear reduction unit and often have vibration problems. these vibrationtorsional 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.
