An apparatus (10) for transporting and metering particulate material including a transport duct having an inlet (14), an outlet (16), and at least one moving surface located therebetween having a downstream facing drive surface (56). The apparatus further includes a motive device for moving the moving surface between the inlet and the outlet towards the outlet (16). The particulate material being compacted sufficiently to cause the formation of a bridge composed of substantially interlocking particulates spanning the width of the transport duct. The bridging of the particulates causes the particulates to become semi-hydrostatic in nature such that the force exerted by the downstream facing drive surface (56) upon particulates within the transport duct drives the entice mass of material through the transport duct towards the outlet (16). The apparatus is used to transport and meter particulate material under ambient conditions and against pressure.

L'appareil (10) permet de transporter et de doser un matériau particulaire et comprend un conduit de transport ayant une admission (14), une sortie (16) et au moins une surface de déplacement située entre l'admission et la sortie et ayant une surface d'entraînement (56) regardant en aval. L'appareil comprend également un dispositif moteur permettant de mettre en mouvement la surface de déplacement entre l'entrée et la sortie, dans le sens allant vers la sortie (16). Le matériau particulaire est suffisamment compacté pour former un pont constitué de particules imbriquées entre-elles et enjambant la largeur du conduit de transport. Cet effet de pont des particules les rend de nature semi-hydrostatique de sorte que la force exercée par la surface d'entraînement (56) sur les particules dans le conduit de transport assure le déplacement de toute la masse de matière particulaire dans le conduit de transport vers la sortie (16). L'appareil est utilisé pour transporter et doser un matériau particulaire dans des conditions ambiantes et contre une pression.
