Abstract

Pneumatic conveying apparatus for powdery or granular materials, comprising a tank provided with a loading hole in its upper part and, in the lower part, an outlet hole connected to a transport pipe into which a supply pipe with air ends. (or other gas) compressed, the lower portion of the tank containing a porous wall sealed with a seal to the outlet orifice in order to form, in the tank, a lower chamber connected by a fluidization pipe with the supply pipe with compressed air, a first normally open valve but whose control is modulated as a function of the prevailing pressure in the transport line, which is provided on the fluidization line and a second normally open and control valve is modulated as a function of pressure (B) in the supply line with compressed air below the beginning of the fluldization line, characterized in that the second valid The valve, which is normally only partially open, is controlled so that it only opens more when the first valve is completely closed.
