摘要：Apparatus for blending pulverulent material which employs the technique offluidizing the material by means of an aerated silo bottom. The silo bottom is divided intoquadrants with air under pressure supplied to each quadrant. While each of thequadrants is being aerated, a greater volume of air may be supplied to any one of thequadrants so that the material in that quadrant will spill over onto the adjacentquadrants and the material in the adjacent quadrants will flow into that quadrant tothereby blend the material in the silo. The apparatus employs a novel aeration unit whichincludes a gas conducting pipe dimensioned to act as a receiver so that the aeration unitsmay be of substantial length.
