Abstract：

The mixing and segregation processes of binaty granular mixture of particles with different properties(size and densities) subjected to horizontal osillatory excitation are investigated in this study. The spatial distributions of vibrated binary mixture are visualized by experiment and DEM simulation and get good agrcement.The time evolutions of pattern formarions show that the stripes perpendicular to the driving direction are developed. The segregation transitions of granular mixtures are strongly dependent on the volurne fractions of different species，the particles，properties and the vibration conditions.For understanding the extent of the segregation，the segregation intensity wes determined to quantify the segregation rate of mixtures.We show that the segregation rates of the mixtures increase with the sizes ratio，density ratio and vibration strength.
