Research on the Vertical Vibration Characteristics of

The rolling mill with hydraulic system is widely used in the production of strip steel. For the problem of vertical vibration of the rolling mill the effects of different equivalent damping coefficient leakage coefficient and proportional coefficient of the controller on the hydraulic screw down system of the rolling mill are studied respectively.

Causes And Treatment Of Vertical Mill Vibration

 · The vertical mill can clearly feel the impact of the rising grinding pressure on the vibration of the mill. When the feeding amount is fixed and the pressure is too high the grinding capacity will be greater than the capacity required for the material to become the finished product resulting in the vibration of the mill.
