<p>A regenerating system for waste powder coating is provided to reduce cost of law material by regenerating waste powder coating and to produce powder coating having good and uniform quality by mixing and melting waste powder coating with virgin powder coating uniformly. The regenerating system for waste powder coating includes a mixer, an extruder and a crusher. The extruder includes a barrel(40) and a shaft(50). The inside of the barrel(40) is divided into a transfer section(A), a first mixing section(B), a second mixing section(C) and an extruding section(D). The transfer section(A) transfers injected powder coating in a rear direction by forming a screw edge(52) on the outer circumferential surface of the shaft(50). In the first mixing section(B), mixing wings(54) are formed to go crisscross against the direction of the diameter of the shaft(50) a little on the outer circumferential surface of the shaft(50).</p> |
