Abstract：

The mixing and segregation processes of  binary granular mixture of partcles with different properties (sizes and densities) suvjected ti hor zontal oscillatory exciation are investigated in this study . The spatial distributions of vibrated binart mixture are good agreement . The time evolutions of pattem formation show that the stripes perpendicular to the  driving direction are developed . The segregation transitions of granular mixtures are stongly dependent on the volume faction of fifferent species ，the particles properties and the vibration conditions.The mechanism of segregation processes is strongly dependent on the momentum exchange of each species .the particles properties and the vibration conditions The mechanism of segregation processes is strongly dependent on the momentum exchange of each species The drag forces provided by friction with the tray influence the segregation pjenomena of the segregation the segregation intensity was detrnined to qyabtify the segregation rate if mixtures We shiw that the segregation rates of the the mixtures increase witth the sizes ratio density ratio and vibration srrenth .
