Die Erfindung betrifft ein Verfahren zum vertikalen Mischen von gasförmigen, flüssigen, pulverförmigen und/oder pastösen Produkten mit z.B. einer in einem Gehäuse angeordneten Hohlwelle (2) und Innenwelle (3), wobei an der Hohlwelle (2) paddelförmige Mischwerkzeuge (4) und an der Innenwelle (3) eine unterhalb eines Auslasses (8) des Mischers (1) angeordnete Austragsvorrichtung(9) vorgesehen ist. Der Mischer (1) ist dabei im Betriebszustand voll gefüllt und das Produkt (11) und Zugaben werden mittels der Mischwerkzeuge (4) an die Innenwand des Gehäuses gedrückt. das Produkt fliesst aufgrund der Schwerkraft stetig nach unten und wirkt den teils rückwärtsfördernden Paddeln entgegen. Der kontinuierliche Produktfluss wird mit dem am Auslass (8) vorgesehenen Drehschieber (9) geregelt. Der Mischer (1) eignet sich insbesondere als Dosiervorrichtung und/oder zum Befetten von Extruder- und/oder Expanderprodukten.

A blender assembly including a blender vessel and a blender hub. The blender hub having a plurality of first guide elements. The blender vessel having a rim, the blender vessel further having a plurality of second guide elements that each cooperate with a respective one of the first guide elements for forming a coupled and a sealed engagement to the blender hub. By releasing the coupling, the first and second guide elements cooperate to provide a two-stage release. A first stage of the release breaking the sealed engagement, and maintaining a loose coupled engagement, between the blender hub and the bender vessel. A second stage of the release, subsequent to the first stage of the release, releasing the coupled engagement between the blender hub and the blender vessel.

On met en contact au moins un monomère gazeux dans les conditions de réaction avec un catalyseur solide, dans une zone de polymérisation agitée. On utilise une zone de polymérisation (24) délimitée par une paroi sphérique (S4) et on réalise l'agitation à l'aide d'un ensemble-turbine (T4) à pales, entraîné en rotation, lesdites pales affleurant ladite paroi sur 10 à 60% de sa surface, les particules de catalyseur ainsi que la poudre de polymère (P) en croissance étant entraînées par la force centrifuge sur au moins une partie de la paroi sphérique et retombant dans la partie centrale de la zone sphérique, en assurant ainsi un brassage énergique et uniforme et sans zone morte. L'invention concerne aussi un réacteur de forme générale sphérique. Application à la prépolymérisation, à l'homopolymérisation et à la copolymérisation des oléfines.

The invention relates to a mixer-transport apparatus for floor mortar and the like, comprising a mixing tank having a filling hole that can be sealed and a transport hose connected to the mixing tank for the pneumatic transport of an earth-humid sand-cement mixture to a site where it is used. According to the invention a remote-controlled shut-off valve (23) is arranged for pivotal movement about a vertical shaft (20) is arranged at the filling hole (18) of the mixing tank (5). The vertical valve shaft (20) can be moved vertically over an adjustable distance (X) between a pivoting position, in which the valve (23) is just clear of an O-ring (17) mounted in an annular groove (16) provided in the bottom surface of a ring (14) surrounding the filling hole (18), and a sealing position, in which the valve (23), owing to the pressure in the mixing tank (5), is pressed into sealing engagement with the O-ring (17).
