Abstract: Apparatus for feeding fine particulate material, comprising a supply chamber having a foraminous bottom member and superposed brush arms for brushing the material therethrough at a regulatable rate. A collecting funnel member is disposed beneath the foraminous member, with its large end open upward to receive the material. Conveying gas is admitted into the funnel member and passes out through the bottom opening of the funnel with the particulate material entrained therein. In three embodiments the funnel member is vibrated to maintain uniform flow of the material and gas may be admitted into the upper end of the funnel. In another embodiment the gas is admitted through gas manifold conduits rotating along a stationary funnel wall, and is directed along wall scrapers supported on these conduits. A vibratile screen preferably is interposed between the foraminous member and the upper end of the funnel to assist in deagglomeration of the falling particles and in obtaining uniform feeding of the material.
