2023-02-02
The twin-screw extruder is divided into the following system parts:
1. Feeding system: including hopper, stirring motor and feeding motor. It can prevent material accumulation and facilitate its smooth entry into the feed port.
2. External heating system: mainly use the heating rod and cylinder to heat the material efficiently and promote plasticization.
3. Cooling system: The heat exchange system composed of heat transfer oil or water is used to reduce the heat of the fuselage, so as to effectively control the temperature of the cylinder.
4. Hydraulic screen changing system: Use replaceable filter screen to intercept impurities, improve the degree of plasticization, and ensure the uniformity and stability of the quality of the output materials.
5. Vacuum system: extract moisture and other low molecular volatiles from the material.
6. Electronic control system: responsible for monitoring and controlling the relevant equipment of the main and auxiliary material system.
7. Screw system: an important part of the twin-screw extruder, which can be divided into a conveying section, a melting section (exhaust port), a plasticizing section (vacuum port), and a discharge section.
The screw system mainly completes the plasticization and conveying process of the material, which has a great influence on the performance and quality of the finished product. The screw parameter settings of different models and equipment from different manufacturers are different, so it needs to be paid attention to.
Segmentation of the screw
The screw system of parallel twin-screw extruder is generally divided into 4 sections: conveying section, melting section (exhaust port), plasticizing section (vacuum port), and discharge section.
1. Conveying section: it is used to convey materials and prevent material return.
2. Melting section: This section makes the materials fully melt and mix through heat conduction and frictional shearing.
3. Plasticizing section: to further melt and mix the components of the material, with the function of distributive and dispersive mixing.
