  • Method of separating granular pourable materials of different densities in a gaseous or liquid medium
    Patent number: 4191642
    Abstract: A method of separating granular pourable materials in fluidized bed layers formed by fluid media. These layers are withdrawn by a fluidizing medium from the top downwardly one after the other down to slightly above the border surface of the lowest layer but one. Subsequently, the fluidizing medium which remains above the residual layer is rotated, and the residual layer is completely withdrawn by means of the thus created secondary radial flow toward the central region.
