Abstract

Procédé et appareil pour le triage par grosseur de solides véhiculés par un liquide Un tuyau principal d'arrivée communique transversalement avec un tuyau auxiliaire 10 par des fentes 12 dont la largeur augmente graduellement d'amont en aval et dont la section s'élargit graduellement de 9 vers 10. Les plus gros solides descendent sur le fond du tuyau 9, le long duquel ils sont entraînés dans un concasseur. Les petites solides traversent les fentes 12 sans trop risquer de les boucher du fait que ces fentes s'étendent suivant la direction d'écoulement et ont une section trapézoïdale. Application notamment au triage des déblais d'excavation
