Abstract
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 vertically aligned cylindrical mixers, including means to transfer product from the first mixer to the second mixer. Each mixer contains six or more vertically aligned partition walls that extend radially from the midpoint 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 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.
