ABSTRACT:
In a centrifugal separator, in particular for separating light materials, such as grass seed, from an air flow, a whirl chamber is provided between a circumferential wall of the separator casing and a radially inner filter consisting of a louvred shell imparting a change of direction of about 180.degree. to the air flow on its way from the whirl chamber to the air outlet of the casing, thereby creating within the shell a counter-rotating whirl of air and material passed through the slits together with air.
To separate such material from the air, the shell is provided with a vertically extending slot associated with an ejector rail adapted to remove the outer portions of the counter-rotating whirl and feed them back for renewed separation in the whirl chamber of the separator casing. The slits may then be given such a size that they will not be blocked up by the material or give rise to an increased loss of pressure, as the ejector rail provides for regaining the material passed through the slits.
