Abstract

An improved closed apparatus for conveying powder materials from a storage region to at least one region to be supplied. The apparatus includes at least one horizontal conveyor formed by a lower gas flow duct, an upper duct for flow of the powder and gas, and a porous wall separating the ducts. At least one conduit supplies gas to the lower duct, permitting the establishment of a pressure Pf. The conveyor is provided with at least one balancing column the height of filling of which balances the pressure Pf of the potential fluidization gas for the purpose of potentially fluidizing the material filling the conveyor.
