The invention discloses a twin-screw extruder with specially crafted
yin and yang rotor profiles. The invention belongs to the field of twin-screw extruder, and especially relates to a twin-screw extruder with specially crafted
yin and yang rotor profiles. The extruder is an
extrusion device used for carrying out mixing and
extrusion upon particle raw materials. An extruder main body arranged on a frame is composed of a
machine head, a cylinder, a gas
discharge port, a heating and cooling device, a yin rotor, a yang rotor, a feeding device, and an end cap. The gas
discharge port is arranged on the cylinder on a place corresponding to a gas
discharge section. The feeding device is arranged on the cylinder on a place corresponding to a melting section. The heating and cooling device is covered on the outer wall of the cylinder. The
yin and yang rotors with a feeding section, the melting section, the gas discharge section, and a measuring section are composed of thread sections, kneading disc elements, and toothed disc elements. When the extruder operates, large mixing capacity, shearing capacity, plasticizing and kneading uniformity, and the like can be provided. The device can be widely applied in
processing and molding of various materials such as plastic, rubber, food, and
medicine preparation.
