In order to improve the efficiency in agitation process, the mixer using a vibration impeller with reciprocating motion in cylinder vessel is developed. This impeller is levitated by repelling force of permanent magnet executes vibrating motion. In order to increase the resonance frequency of the vibration impeller, new type of the vibration impeller are developed, and the magnetic levitation system of the mixer is improved by using waterproofed Neodymium magnets. The analytical model of the vibration impeller becomes the nonlinear oscillator because the magnetically repulsive force has strong non-linearity. The equation of motion of the impeller with non-dimensional form is derived to analyze the motion of the vibration impeller. Experimental devices on a trial basis are manufactured. In older to investigate the characteristics of motion of the vibration impeller, some experiments are perfumed. The frequency responses of amplitude of the vibration impeller are shown. When the vibration impeller is excited in a container with water, the resonance frequency of the vibration impeller of the developed mixer can be in excess of 15.5Hz. The peak-to-peak amplitude of the vibration impeller is 3.4mm at the resonance frequency.
