Abstract

Disclosed herein is an apparatus for dispersing a nanocomposite material. That apparatus includes an inner chamber in which a metal powder, a nanocomposite material and inner pellets are charged. The inner chamber also includes a plurality of apertures each having a smaller diameter than that of each inner pellet. Furthermore, the apparatus includes an outer chamber that surrounds the inner chamber and includes outer pellets in a space between a wall of the inner chamber and a wall of the outer chamber.

First claim

What is claimed is:

1. An apparatus for dispersing a nanocomposite material, comprising:
an inner chamber configured such that a metal powder, a nanocomposite material and a plurality of inner pellets are charged therein, wherein the inner chamber includes a plurality of apertures each having a smaller diameter than each of the inner pellets, and the plurality of apertures are formed in a wall of the inner chamber
an outer chamber that surrounds the inner chamber, wherein the outer chamber includes a plurality of outer pellets in a space between the wall of the inner chamber and a wall of the outer chamber; and
a control unit operated by a controller and configured to rotate the inner chamber and the outer chamber;
wherein the control unit is operated by the controller such that a mixing time in the outer chamber must not exceed a mixing time in the inner chamber.

2. The apparatus of claim 1 , wherein a diameter of each aperture is about 3˜10 times larger than the diameter of the metal powder.

3. The apparatus of claim 1 , wherein a diameter of each inner pellet is about 10˜200 times larger than the diameter of the metal powder.

4. The apparatus of claim 1 , wherein the plurality of outer pellets are larger than the plurality of inner pellets.

5. The apparatus of claim 1 , wherein a diameter of each outer pellet is about 200˜1000 times larger than the diameter of the metal powder.

6. The apparatus of claim 1 , wherein the control unit operated by the controller is configured to rotate the inner chamber and the outer chamber to obtain the mixing time in the inner chamber of about 5˜300 minutes and the mixing time in the outer chamber of about 5˜180 minutes.

7. The apparatus of claim 1 , further comprising:
an outermost chamber that surrounds the outer chamber and includes a plurality of outermost pellets in a space between the wall of the outer chamber and a wall of the outermost chamber, wherein the wall of the outer chamber includes a plurality of apertures each having a diameter smaller than that of each outermost pellet.

8. The apparatus of claim 7 , wherein the outermost pellets are smaller than the outer pellets.
