A centrifugal classifier comprising a housing, which is provided with inlets for material to be classified and classifying air or with an inlet for material to be classified and classifying air and with outlets for fines and for coarses, and at least one rotor, which essentially consists of an annular series of blades and is movably mounted in the housing. The rotor is movably mounted in the housing by at least one bearing, which is adapted to be purged by a fluid and which serves also as a seal between the rotor or rotor shaft and the housing.
