Characteristics of Twin Screw Extruder

1. The twin-screw extruder is built on the building block principle. According to changes in the material system and process requirements, the screw configuration, barrel structure, length-to-diameter ratio, number of feeding and exhaust positions, screen changing and pelletizing methods, motor automatic control mode, and so on can be adjusted and optimized. It achieves a unified balance of broad multi-function, multi-purpose, versatility, and adaptability to specific needs.


2. The basic type of dual screw extruder: the screw element is a computer-designed fully meshing conjugate type with excellent self-cleaning and arbitrary interchangeability. With over ten years of rich experience in screw configuration research, development, and software technology, our dual screw extruder can realize various functions and technological processes. As needed, convey plasticization, mixing and kneading, shearing, dispersing, homogenizing, exhausting and devolatilizing, and pressure-reducing extrusion. As a result of the never-ending emergence of new polymer materials and processes, various new screw elements and combination configurations have been continuously introduced accordingly.


3. The main screw element of the dual screw extruder is connected with the mandrel. It adopts the horizontally synchronized involute spline form, which fully taps the potential of the limited structural space and takes into account the realization of higher working torque and larger screw working volume.


4. The twin screw extruder provides a wider choice for users at all levels according to the requirements of different material processes and uses.


5. The twin screw extruder's new torque distribution transmission device, strengthened design safety capacity, high-precision hard tooth surface grinding processing, all key bearings are imported. Its lubrication system possesses interlocking protection with the pursuit of higher reliability.


6. The multi-form metering and feeding structure and system of the twin screw extruder, single-screw, twin-screw, hollow spring type, meshing, non-meshing, etc., can cover all kinds of material conditions.


7. The twin screw extruder has a special pelletizing system, including water-cooled strand cutting, air-cooled strand cutting, air-cooled die hot face pellet, water ring die hot face pellet, eccentric water mist hot pellet, and underwater die face cut pellets, etc. You can choose according to your needs.


8. The conventional twin screw extruder is made of nitrided steel with surface nitriding treatment, which can meet the requirements of most operations. Special materials and treatment methods such as corresponding corrosion resistance, wear resistance, or abrasion resistance can be selected.


9. The twin screw extruder has low vibration and low noise. The whole machine can be installed without foundation and can be placed on flat ground, which reduces the requirements for site and installation and makes it more convenient to use.
