Abstract
A device for distributing powdery materials comprises a suspension sleeve which extends a rotary cage axially upwards through a plate. A running ring is fixed using a first collar to a suspension sleeve and using a second collar to an annular flange supported by the support structure above the horizontal plate. A ring forms part of the supply channel and is coaxial with the suspension sleeve. Leaktightness is ensured by a first leaktight seal between the suspension sleeve and this ring, and by a second leaktight seal between the suspension sleeve and the horizontal plate.
