Summary:Installation for dosing a powdery material comprising at least one hopper (TC), a conveyor (2) having a receptacle (6) provided with a filling opening underneath said hopper (TC), a weighing system (4) able to weigh at least said receptacle (6), means (20) able to move the weighing system (4) and the receptacle (6) so as to distance the receptacle (6) from the conveyor (2) and so that, in at least one distanced position, the weighing system (4) weighs solely the receptacle (6) and its content, said weighing system (4) comprising a first balance (8) supporting the receptacle (6) and a second balance (10) on which the first balance (8) rests. Said installation can comprise individual hoppers (T1, T2, T3) upstream of the hopper (TC), making it possible to produce mixtures of powders. Installation de dosage d'un matériau en poudre comportant au moins une trémie (TC), un convoyeur (2) disposant d'un récipient (6) muni d'une ouverture de remplissage en dessous de ladite trémie (TC), un système de pesée (4) apte à peser au moins ledit récipient (6), des moyens (20) aptes à déplacer le système de pesée (4) et le récipient (6) de sorte à écarter le récipient (6) du convoyeur (2) et de sorte que, dans au moins une position écartée, le système de pesée (4) pèse uniquement le récipient (6) et son contenu, ledit système de pesée (4) comportant une première balance (8) supportant le récipient (6) et une deuxième balance (10) sur laquelle repose la première balance (8). Ladite installation peut comporter des trémies individuelles (T1, T2, T3) en amont de la trémie (TC), permettant de réaliser des mélanges de poudres.
