A method for feeding and conveying material in a pneumatic material conveying system, such as a waste conveying system, which conveying system comprises at least one feed point (61) of material, particularly of waste material, a material conveying pipe (100) which is connectable to the feed point (61), a separator device (20) in which the material being conveyed is separated from conveying air, and means (3, 4) for providing a pressure difference in the conveying pipe (100) at least during the conveyance of the material. Underpressure is provided in the conveying pipe (100) at least at the point of the feed point (61) intended to be emptied, the feed points are emptied to the conveying pipe (100) using an emptying sequence in which first is emptied a feed point located closer to the separator device (20) in the material conveying direction and next a feed point (61) located substantially farther from the separator device (20) in the material conveying direction.
L'invention concerne un procédé permettant d'amener et de transporter des matières dans un système de transport de matières pneumatique, notamment un système de transport de déchets. Selon l'invention, le système de transport comprend: au moins un point d'alimentation (61) en matières, en particulier en déchets; un conduit de transport (100) de matières pouvant être relié au point d'alimentation (61) en matières; un dispositif de séparation (20) dans lequel la matière transportée est séparée de l'air de transport; et un moyen (3, 4) permettant de produire une différence de pression dans le conduit de transport (100), au moins pendant le transport des matières. Une sous-pression est crée dans le conduit de transport (100), au moins au point d'alimentation (61) destiné à être vidé, les points d'alimentation étant vidés dans le conduit de transport (100) selon une séquence de vidage dans laquelle le point d'alimentation le plus proche du dispositif de séparation (20) dans la direction de transport des matières est vidé en premier, puis est vidé un point d'alimentation (61) sensiblement plus éloigné du dispositif de séparation (20) dans la direction de transport des matières.
