Abstract

A mixing apparatus for uniformly mixing granular solid materials, comprising a reservoir, a receiver disposed below said reservoir, a plurality of conduits extending upwardly of said reservoir and formed with a series of openings at vertically spaced intervals along the the conduits arranged in communication with the interior of said reservoir for uniform sampling and extraction of the material from said reservoir, said conduits and openings being spaced apart so that geometrically substantially equal sections of the materials of the hopper are disposed in communication with the covered openings more upper of each of the ducts regardless of the level of the material in the hopper, having the indicated exit ducts to discharge the material inside said receiver, and means to maintain a substantially equal material flow rate descending through the aforementioned ducts and in such an amount that the materials passing down through said ducts is less than the free fall rate of the materials and so that only the most superior of the openings of each duct disposed under the level of the materials in said deposit it is operative to extract the materials from the repeated deposit.
