Abstract

Ce dispositif amélioré (30) destiné au transport de substances particulaires (40) à doser se compose d'un conduit de transport (36) muni d'un orifice d'entrée (32), d'un orifice de sortie (34) et d'au moins une surface en mouvement (31) située entre ces deux orifices, et dont la surface d'entraînement est orientée vers l'aval. Le dispositif comporte également un équipement moteur destiné à animer la surface d'entraînement (31) entre l'orifice d'entrée (32) et l'orifice de sortie (34) en direction de cet orifice de sortie. Le dispositif comporte en outre un équipement de compactage des substances particulaires de façon suffisante pour la formation d'un pont se composant essentiellement de substances particulaires (40) reliées entre elles et s'étendant sur toute la largeur du conduit de transport (36). Ce dispositif est destiné au transport et au dosage de substances particulaires dans les conditions normales d'environnement et de pression.
