2045638 9008723 PCTABS00001 A feeder for particulate material for connecting a mechanical feeding device (14) to a pneumatic conveying line comprises a funnel (7) formed of a gas pervious material which is mounted in a closed outer housing (1) formed of an impervious material wherein the walls of the funnel and the outer housing together defining a plenum chamber (10) which is provided with an inlet (11) for connection to supply of conveying gas under pressure. The funnel (7) is adapted to form a sealing engagement with the outlet of the mechanical feeding device (14) and the funnel (7) at or towards its narrow end communicates with the pneumatic conveying line. In use, conveying gas, under pressure, enters the plenum chamber (10) and then passes through the walls of the funnel (7). The particulate material delivered to the funnel (7) by the mechanical feeding device is flushed out of the funnel and into the conveying line by the conveying gas. The feeder enables a uniform flow of particulate material using one pressurized gas supply for conveying particulate material from bulk storage to discharge.
