ABSTRACT:
A liquid agitator having agitator blades attached to a rotary shaft centrally located within a liquid containing vessel is provided with a vibration suppressing stabilizer, consisting of one or more plates attached to the agitator shaft. The span of the stabilizer is somewhat less than the diameter of the agitator blades, but equal to at least about 20% of the blade diameter. The height of the stabilizer is also equal to at least about 20% of the blade diameter. The stabilizer is located in a portion of the liquid within the vessel which rotates about the agitator shaft with a tangential velocity proportional to the distance from the shaft. Interaction between this liquid and the stabilizer suppresses agitator vibrations.
