This paper describes the separation and transportation of works with various friction coefficients using elliptical vibration. Elliptical vibration machine has a horizontal vibratory system and a vertical vibratory system. Transportation velocity is depends on amplitude, phase difference and friction coefficients. When a friction coefficient differs by form or material of works, transportation velocity is changed also including the direction of positive/negative, even if elliptical vibration machine has same amplitude and phase difference. Using this phenomenon, works with which different friction coefficients can be separated by transporting difference direction.
