 note = {In order to improve mixing efficiency for mixing process, vibratory mixer using stirring fin levitated in mixing tank by magnetically repulsive force is developed. Stirring fin performs reciprocating motion by excitation of periodical motion of external magnet form outside cylindrical mixing tank. Mixed liquid in the mixing tank can be isolated from external environment by adopting this excitation method, and then contamination into a mixed liquid can be prevented. In order to vibrate the string fin largely by magnetic repulsive force, magnetic spring with soft spring characteristic to support the stirring fin is used. This magnetic spring have strongly softening nonlinearity. The greatest characteristic of the developed vibratory mixer is to utilize nonlinear resonance effectively. In order to clarify vibration characteristics of stirring fin, some experiments are executed. The frequency responses of peak-to-peak (pp) amplitude and waveforms of stirring fin are shown. When stirring fin is excited in mixing tank filled with water, pp amplitude of stirring fin is about 67 mm at resonance frequency 2.1 Hz. This vibration of the string fin with low frequency and large amplitude can be used effectively for various liquid-liquid or liquid-powder mixing. In addition, damping coefficient of the stirring fin in the water is identified by the phase-method. It is confirmed that damping coefficient of stirring fin in mixing tank changes depending on the frequency.},
