<p>Apparatus is provided for blending batches of particulate material that are compositionally heterogeneous into batches of material that are compositionally uniform. The apparatus consists of two or more cylindrical static mixers, each mixer being substantially identical in volumetric capacity and construction. Each mixer contains six or more vertically aligned partition walls (31-36) that extend radially from the midpoint (37) of the mixer to the wall to divide the mixer into at least six storage compartments of substantially equal volumetric capacity. The vertical partition walls (31-36) differ in height in a regular descending order so that as material is charged to and fills one compartment, it overflows the shorter wall to fill the adjacent compartment. One embodiment includes means for feeding particulate material successively through each of the static mixers. A second embodiment includes means for simultaneously discharging lots of particulate material from each of the mixers at a substantially uniform rate into a common conveying means.</p> |
