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