Abstract

La présente invention concerne le mélangeage en continu de solides pulvérulents et de liquides. Elle propose un procédé de mélangeage qui consiste : - à introduire en continu la phase liquide dans une cuve de mélangeage; - à introduire en continu la phase solide dans ladite cuve avec un débit tel que soient respectées les proportions désirées de solide et de liquide dans le mélange; - à assurer la rotation des produits contenus dans la cuve de façon à former un vortex; - à régler les débits d'alimentation en solide et en liquide pour que se maintienne constamment un certain état de remplissage de la cuve; - à évacuer en continu le mélange des produits pour que se conserve cet état de remplissage. Elle propose également un dispositif pour mettre en oeuvre le procédé. Elle trouve une application dans la préparation des liants hydrauliques et en particulier dans la préparation en continu d'un mélange de plâtre et d'eau.The present invention relates to the continuous mixing of powdery solids and liquids. It proposes a mixing process which consists: in continuously introducing the liquid phase into a mixing tank; - Continuously introducing the solid phase into said tank at a rate such that the desired proportions of solid and liquid in the mixture are observed; - to ensure the rotation of the products contained in the tank so as to form a vortex; - Adjusting the solid and liquid feed rates so that a certain state of filling of the tank is constantly maintained; - continuously evacuating the mixture of products so that this state of filling is preserved. It also proposes a device for implementing the method. It finds an application in the preparation of hydraulic binders and in particular in the continuous preparation of a mixture of plaster and water.
