A vertical turbulent separator for classifying aqueous paper material comprises a lower cylindrical inlet chamber having an inlet arranged thereon to impart to the aqueous paper material a rotational flow path, an upper cylindrical working chamber and an intermediate annular body connecting the lower and upper chambers. The aqueous paper material is separated as a result of centrifugal forces into fractions of varying specific weight distributed in the form of rotational rings along the inner walls of the annular body and working chamber. A first outlet is provided on the annular body for removing a heavy fraction, and a second outlet and a discharge tube are provided on the working chamber for removing respectively a classified fraction and a light fraction. The separator of the invention is particularly useful for separating granules of polystyrene foam. |
