Abstract

L'invention concerne un procédé pour le transport d'un matériau en vrac au moyen d'un dispositif de transport présentant un canal de transport et au moins deux éléments de transport (266, 269) se trouvant de manière volante dans un canal de transport, dans lequel les éléments de transport sont entraînés mécaniquement dans le sens du transport dans une première section du canal de transport avant que le matériau en vrac ne soit introduit dans le canal de transport dans une deuxième section du canal de transport. Le matériau en vrac est transporté par le mouvement des éléments de transport le long du sens de transport dans une troisième section du canal de transport, le premier élément de transport (269) étant poussé dans cette troisième section du canal de transport par le deuxième élément de transport (266) et/ou par le matériau en vrac au travers du canal de transport dans le sens du transport. L'invention comprend également un dispositif de transport pour réaliser ce procédé.
