The vertical roller mill equipped with an internal classifier is often said to be more energy efficient than tumbling mills working on the same material and the same size step (e.g. Gerold et al., 2012). It is long established in the cement industry and gains more and more importance in the industrial mineral and iron ore sectors.

A vertical vibration model of a 3-DOF strip rolling mill with a compound roll bearing failure on the outer raceway and inner raceway is established. Through MATLAB simulation, the vertical vibration characteris-tics of the strip mill work roll are compared and analyzed under the condition that the outer raceway
