Abstract

Il est décrit une centrifugeuse décanteuse qui comporte un bol; un transporteur à vis; un tube ascendant; une chambre pour les matières premières; un accélérateur dans la chambre pour les matières premières; et une buse de redirection des matières premières; le transporteur à vis comporte un corps de transporteur et une vis sans fin, le transporteur à vis définissant un passage axial entre le corps de transporteur et un bord orienté de manière radiale vers lintérieur de la vis sans fin; la centrifugeuse décanteuse est structurée de telle sorte que, lors de son utilisation, un mélange de matières premières passe à travers le tube ascendant et dans la zone des matières premières où la vitesse angulaire du mélange de matières premières est augmentée par laccélérateur, le mélange de matières premières sort ensuite de la zone des matières premières, est redirigé par la buse de redirection des matières premières dans une direction axiale vers une chambre de sédimentation à lintérieur du bol et à travers le passage axial, et la rotation du transporteur et du bol provoque une sédimentation à lintérieur du bol, pour séparer les solides et les liquides dans le mélange de matières premières.
