The invention relates to a method for transporting a powdery material by potential fluidisation, according to which a device is installed between the supply region and the region to be supplied, said device comprising at least one substantially horizontal conveyor (3), called "aeroducting", which has a lower duct (6) for the circulation of a gas and an upper duct (7) for the circulation of the powdery material, the lower duct and the upper duct being separated by a porous gas-permeable wall (5). According to said method, the upper duct is filled with the powdery material and the lower duct is supplied with pressurised gas enabling the potential fluidisation of the powdery material in the upper duct provided with at least one pressure equalisation column (4.1, 4.2). The minimum bubbling speed corresponding to the maximum vacuum rate is determined in advance, and the fluidisation pressure is regulated to a value such that the fluidisation speed of the gas is between 0.8 and 1.5 the minimum bubbling speed, preferably between 0.9 and 1.3 times the minimum bubbling speed.
Procédé permettant de transporter, par fluidisation potentielle, un matériau pulvérulent, dans lequel on installe un dispositif entre la zone d'alimentation, et la zone à alimenter, ledit dispositif comprenant au moins un convoyeur (3) substantiellement horizontal appelé "aérocanalisation", qui comprend un canal inférieur (6) destiné à la circulation d'un gaz et un canal supérieur (7) destiné à la circulation du matériau pulvérulent, ledit canal inférieur et ledit canal supérieur étant séparés par une paroi poreuse (5) pouvant être traversée par ledit gaz, procédé dans lequel on remplit le canal supérieur avec ledit matériau pulvérulent et on alimente le canal inférieur en gaz sous une pression permettant la fluidisation potentielle dudit matériau pulvérulent dans ledit canal supérieur', ledit canal supérieur étant muni d'au moins une colonne d' équilibrage (4.1, 4.2). Dans ce procédé, on détermine au préalable la vitesse minimale de bullage, qui correspond au taux de vide maximum et on règle la pression de fluidisation à une valeur telle que la vitesse de fluidisation dudit gaz est entre 0,8 et 1, 5 fois ladite vitesse minimale de bullage, de préférence entre 0,9 et 1,3 fois ladite vitesse minimale de bullage,
