ABSTRACT:
An apparatus for deagglomerating powder in a mixture of liquid and powder, which contains a mixing tank, a rotatable shaft, at least two agitator disks connected to such shaft, and a vortex suppressor disposed above the topmost of such disks at a distance which is from about 30 to about 60 percent of the inside diameter of the mixing tank. The mixing tank has a height which is from about 9 inches to about 20 feet, and an inside diameter of from about 3 inches to about 3 feet; and the ratio of such height to such inside diameter is at least about 3/1. The distance between the agitator disks is from about 50 to about 200 percent of the diameter of the first agitator disk; each of such disks contains from about 4 to about 12 teeth attached around its periphery; the frontal area of each of said teeth is from about 0.02 to about 1.5 square inches; and each of such teeth is so attached that it forms an angle between the front face of the tooth and the radius of said disk of from about 5 to about 45 degrees. The agitator disks preferably contain two halves, each of which is attached to a hub connected to the shaft.
