Abstract:Simulation law and physical simulation were used to study the kinematic behaviorof inclusions in electromagnetic separation. It was found that velocity of spherical non-metallic particles shares different functions in different Reynolds number range. The function of spherical particle's velocity has been got by confirming the relationship between Reynolds number and resistance coefficient when Reynolds number is 0.2～10. For non-spherical particles, the moving behavior is influenced by shape and orientation while spherical coefficient has nothing to do with the velocity of irregular particles. The influence of orientation of cuboid particle on the electromagnetic expulsive force has been indicated by numerical computation.
