Apparatus for assisting the pneumatic conveying of generally dry particulate matter through a closed conduit is disclosed. The apparatus is for use where vacuum pressure applied at one end of the conduit creates a suction force which moves the dry particulate matter through the conduit, and involves the use of a small tube or the like for injecting a gaseous fluid under positive pressure into the particulate matter to loosen it and enable it to be conveyed through the conduit.
