Abstract
(DE)
Die Erfindung betrifft eine Dosiervorrichtung zum Beschicken von Vorrichtungen, wie z. B. Extruder, Spritzgussmaschinen oder dergleichen, mit Schüttgütern wie Pellets, Spänen, Granulaten, Pulvern, Flakes, Körnern, Mehl oder dergleichen mit einem Gehäuse. Es wird aufgezeigt, wie ein möglichst glatter Durchlauf von derartigen Schüttgütern durch eine derartige Dosiervorrichtung möglich ist, ohne dass es zu Nestbildungen und Durchflussstörungen im Zuführkanal kommen kann.
(EN)
The invention relates to a dosing device for feeding devices, such as extruders, injection molding machines, or the like, with bulk goods such as pellets, chips, granulates, powders, flakes, grains, meal, or the like, having a housing. The invention discloses how as smooth a flow as possible of bulk goods of such type can be achieved by such a dosing device, without allowing nest formation and disturbances in flow in the feeding channel.
(FR)
L'invention concerne un dispositif de dosage avec carter, destiné à alimenter des équipements, tels que des extrudeuses, des machines de moulage par injection ou similaires, en produits en vrac, tels que des boulettes, des copeaux, des granulés, des poudres, des flocons, des grains, de la farine ou similaires. Il est montré comment le passage de tels produits en vrac dans un tel dispositif de dosage peut se produire régulièrement, sans qu'il ne se forme des îlots et des perturbations de l'écoulement dans le canal d'alimentation.
