A system (10) for mixing cementatious material, liquid and aggregate to form concrete includes a cementatious material measuring device (12) which provides dry cementatious material to an enclosed screw conveyor assembly (14). The dry cementatious material is thoroughly mixed with a liquid (68) within the screw conveyor (14) to form a flowable slurry without producing external cement dust pollution. The slurry is output by the screw conveyor (14) into a final product mixing chamber (16) where the flowable slurry is mixed together with aggregate to form concrete. The screw conveyor assembly (14) has an in-line input (20) and output (22), and space-saving diverging/converging conveyor sections (28, 56) to facilitate the retrofitting of existing concrete mixing plants. The conveyor assembly (14) includes a cement metering function as well as a slurry mixing function. A selectively openable and closable bypass gate (90) permits the dry cementatious material to be sent directly to the final product mixing chamber (16) in the event of conveyor failure.
Système de malaxage d'un liant hydraulique, d'un liquide et d'un agrégat pour former du béton. Il comprend un dispositif de mesure du liant hydraulique (12) qui alimente en liant hydraulique sec un transporteur à vis enfermé (14). Le liant hydraulique sec est complètement mélangé à un liquide (68) dans le transporteur à vis (14) pour former un coulis fluide sans produire de pollution extérieure due à la poussière de ciment. Le coulis est expulsé par le transporteur à vis (14) dans une chambre de malaxage du produit final (16) où il est mélangé à l'agrégat pour former du béton. Le transporteur à vis (14) possède une entrée (20) et une sortie (22) en ligne, et des sections divergentes ou convergentes compactes (28, 56) pour faciliter la modification des installations actuelles de malaxage du béton. Le transporteur à vis (14) comporte un dispositif de mesure du ciment et une capacité de malaxage du coulis. Une porte ouvrable et refermable de manière sélective (90) permet d'acheminer directement le liant hydraulique sec à la chambre de malaxage du produit final (16) en cas de défaillance du transporteur.
