The most notable feature of the co-rotating twin-screw extruder is that both the screw and barrel adopt a "building block" design. By combining various threaded elements, the co-rotating twin-screw extruder has the functions of feeding, melting, mixing, exhausting, pressure holding and conveying, realizing various process such as material conveying, plasticizing, shearing, exhausting, pressure holding and extrusion.

Prolonging the service life of the twin screw granulator requires attention to some key aspects, including correct operation, regular maintenance and proper care. Here are some suggestions:1. Correct operation 2. Regular maintenance 3. Cleaning and lubrication 4. Temperature control 5. Avoid no-load operation 6. Repair faults promptly 7. Regularly check the electrical system 8. Staff training 9. Check the cooling system regularly 10. Purchase high-quality raw materials

As the workhorse in the field of compounding, the twin-screw extruder's superior performance and customizability are its advantageous features in this position. It can combine different additives and fillers to achieve different particle shapes and properties with different properties. While a variety of additives and fillers can be processed for extrusion, some methods of obtaining these products can also lead to contamination problems and low flow or low pressure in many areas throughout the barrel.

The template of the extruder consists of a template body with a discharge hole and a heat insulation layer, and is fixed to the die head with a threaded rod. Only when the discharge speed of each die hole is consistent can particles of uniform size be cut out. During use, there are many factors that affect the smooth flow of the template. When the template is severely blocked, it will affect the appearance of the particles, the service life of the cutter, and cause shutdown.

Process parameters that affect mixing in the kneader: 1: Filling coefficient and feeding materials 2: Mixing procedure and feeding sequence 3: Mixing temperature 4: Mixing time 5: Rotor speed

According to whether the axis lines of the twin screws are parallel or not, they can be divided into two types of extruders: those with parallel axis lines and those with intersecting axis lines. The one with parallel axis lines is a parallel twin screw extruder, and the one with intersecting axis lines is a conical twin screw extruder.

When the material moves forward along the screw, it experiences changes in temperature, pressure, viscosity, etc. This change is not the same throughout the entire length of the screw. According to the changing characteristics of the material, the screw can be divided into a feeding section, a compression section and a homoge0nization section.

The specific structure of plastic twin-screw extruders is based on the actual twin-screw extruders, and specially designed twin-screw extruders can be divided into meshing types and non-meshing types according to the relative positions of the two screws. Plastic twin-screw extruders can arrange and combine thread elements and barrel elements of various geometric shapes. Based on experience-theory-practice-test, the design can be optimized for different mixing requirements to adapt to the needs of different process formulas, making the co-rotating twin-screw extruder highly adaptable.
