 · re vibration vertical roller mill. Hello Ashkan, The most important factor which determines the level of vibration in a VRM is the thickness and consistency of the grinding bed. The bed thickness may be affected by the following variables;-Feed rate too low, too high or changing too quickly. Particle size of feed too large or too small.

When the machine is operating under certain driving force, resonance will largely increase the vibration and may cause damage. The rotation speed causing resonance is called 'danger rotation speed'. This could be danger in grinding mill operating. To reduce parts resonance, manufacturers must try to increase the value of 'danger rotation speed'.

A vibration is a variable deflection, thus, no defection means no vibration. Vibrations in a cutting tool are triggered and maintained by a dynamic cutting force. Even in a continuous cut, the cutting force will have small rapid changes in both size and direction around a certain average.
