The transport of 2D powder mixtures is investigated using a model recently proposed by us to describe the fluidization of granular media. We simulate the behaviour of particles placed on a belt having vertical as well as horizontal vibrations. Using Molecular Dynamics we calculate the density field and velocity distributions of the particles and investigate the angular dependence of momentum transfer. We investigate these properties as functions of friction parameters and present predictions that might be checked experimentally.
