Abstract

An apparatus for cutting polymer includes a rotor having a base with a first side and a second side opposite the first side. The rotor includes an outer annular wall extending from the first side and defining a number of slots, an inner annular wall defining a number of slots and extending from the first side and surrounded by, and spaced apart from, the outer annular wall. The rotor also includes blades extending from the first side and positioned within the inner annular wall. A circular-shaped stator also defines a number of slots. At least a portion of the stator is positioned in a space between the outer annular wall and the inner annular wall of the rotor.

First claim

We claim:

1. An apparatus comprising:
a rotor having a base with a first side and a second side opposite the first side, the rotor further including:
an outer annular wall extending from the first side and defining a plurality of slots,
an inner annular wall defining a plurality of slots and extending from the first side and surrounded by, and spaced apart from, the outer annular wall, and
blades extending from the first side and positioned within the inner annular wall.

2. The apparatus of claim 1 , further comprising:
a circular-shaped stator defining a plurality of slots, at least a portion of which is positioned in a space between the outer annular wall and the inner annular wall.

3. The apparatus of claim 1 , wherein the base is disc shaped.

4. The apparatus of claim 1 , wherein the outer annular wall includes a greater number of slots than the inner annular wall.

5. The apparatus of claim 3 , wherein a height of each of the slots is the same.

6. The apparatus of claim 3 , wherein the outer annular wall includes rectangular slots elongated in a direction perpendicular to a surface of the first side of the base and wherein the inner annular wall includes slots elongated in a direction different than the rectangular slots.

7. The apparatus of claim 6 , wherein the slots of the inner annular wall have a width that decreases as the slots extend further from the base.

8. The apparatus of claim 6 , wherein the slots of the inner annular wall have a width that remains constant as the slots extend further from the base.

9. The apparatus of claim 3 , wherein the slots of at least one of the outer annular wall, the inner annular wall, and the stator are evenly spaced apart from each other.

10. The apparatus of claim 3 , wherein the slots of at least one of the outer annular wall, the inner annular wall, and the stator are unevenly spaced apart from each other.

11. The apparatus of claim 1 , wherein the rotor, rim, and hollow cylinder are integrally formed.

12. The apparatus of claim 1 , further comprising:
a shaft coupled to the base.

13. A cutting device comprising:
a rotor having a base with a first side and a second side opposite the first side, the rotor further including:
an outer annular wall extending from the first side,
an inner annular wall extending from the first side and surrounded by, and spaced apart from, the outer annular wall, and
blades extending from the first side and positioned within the inner annular wall; and

a circular-shaped stator, at least a portion of which is positioned in a space between the outer annular wall and the inner annular wall, wherein the outer annular wall, inner annular wall, and stator include slots defined therein.

14. The cutting device of claim 13 , wherein the base is disc shaped.

15. The cutting device of claim 14 , wherein the outer annular wall includes a greater number of slots than the inner annular wall.

16. The cutting device of claim 14 , wherein the outer annular wall includes rectangular slots elongated in a direction perpendicular to a surface of the first side of the base and wherein the inner annular wall includes slots elongated in a direction different than the rectangular slots.

17. The cutting device of claim 16 , wherein the slots of the inner annular wall have a width that decreases as the slots extend further from the base.

18. The cutting device of claim 17 , wherein the slots of the inner annular wall have a width that remains constant as the slots extend further from the base.

19. The cutting device of claim 14 , wherein the slots of at least one of the outer annular wall, the inner annular wall, and the stator are unevenly spaced apart from each other.

20. The cutting device of claim 14 , wherein the rotor, rim, and hollow cylinder are integrally formed.
