ABSTRACT:
The invention relates to an apparatus for separating and recovering solid particles transported by a gaseous flow. The apparatus includes a separation chamber (40), an admission conduit (43) by which the gaseous flow laden with particles arrives, an escape conduit (44) by which the flow leaves after having been relieved of its particles, a discharge conduit (47) toward which the particles separated from the gaseous flow are urged, a movable flap (49) making it possible with the discharge conduit to comprise a particle recovery box, and a helical device (52) placed in the discharge conduit to prevent the particles thus recovered from being re-aspirated by the rising flow that escapes via the escape conduit (44). The invention is applicable to magnetographic printing machines.
