ABSTRACT:
A centrifugal classifier is disclosed having a high and adjustable yield of fine material. The classifier has a substantially cylindrical upright housing with an approximately tangential sifting-air inlet, in which are arranged, at a radial distance from, and centrally of, the casing of the housing, a vane-ring and, at a radial distance, inwardly therefrom, a sifting rotor with a lamination-ring forming radial passages, an inlet for the granular material to be classified opening, at the top, into the classifying area located between the said vane-ring and sifting rotor, and an outlet for the sifting air, charged with fine material, being located adjacent the rotor, the diameter of the outlet corresponding approximately to the inside diameter of the rotor, and the sifting-air inlet and the vane-ring extending over approximately the same axial length as the rotor, characterized in that the classifier as a whole is adapted to pivot about a horizontal axis.
