We study the filling process of a two-dimensional silo with inelastic particles by simulation of a granular media lattice gas (GMLG) model. We calculate the surface shape and flow profiles for a monodisperse system and we introduce a novel generalization of the GMLG model for a binary mixture of particles of different friction properties where, for the first time, we measure segregation both on the surface and in the bulk. The results are in good agreement with a recent theory, and we explain the observed small deviations by the nonuniform velocity profile.
