Critical speed - Wikipedia
All rotating shafts, even in the absence of external load, will deflect during rotation. The unbalanced mass of the rotating object causes deflection that will create resonant vibration at certain speeds, known as the critical speeds. The magnitude of deflection depends upon the following: • Stiffness of the shaft and its support• Total mass of shaft and attached parts

Industrial Mixers - WMProcess
Critical Speed is the rotational speed at which a top entry shaft mixer vibrates dangerously and can cause serious equipment damage. Every rotating shaft has a critical speed at which the natural harmonics of the shaft begin to build and increase the shaft deflection to the point where parts of the mixer may contact the mixing vessel.
