With the widespread use of plastic products, the plastic extruder industry has developed rapidly, with twin-screw extruders being the fastest growing. Today, screw extruders have become an essential product for modern industry. In this article, we will combine the main features and working principles of twin-screw extruders with a brief analysis of their applications.
·What’s the working principle of Twin Screw Extruder?
·What are the features of Twin Screw Extruder?
·Examples of twin-screw extruder applications.
The working principle of a twin-screw compressor is not complicated, where there is no movement to any chemical reaction. For the basic mechanism of the extrusion process, it is simply a screw that rotates in the barrel and pushes the plastic forward. The screw structure is a ramp or slope wrapped around a central layer, the purpose of which is to increase the pressure in order to overcome the higher resistance. In short, a twin-screw extruder is an excellent machine for extruding a variety of different products.
The twin-screw extruder has high working efficiency and a simple structure. It has a wide range of applications and can be applied to the processing of a wide variety of materials. The extrusion process it uses is a highly productive process in the polymer processing field. In addition, its simple structure makes it easy to install and maintain, which greatly reduces the working time.
The twin-screw extruder has a speed of up to plus 500 rpm. This gives it a unique advantage in the processing of highly viscous, heat-sensitive materials. This is a feature that single-screw extruders do not have.
The twin-screw extruder allows for homogeneous dispersion and mixing of powders, and the machine is self-cleaning. The well-balanced and precise feeding system prevents bridging effectively.
The twin-screw extruder is highly customizable and its screw elements can be optimized to suit the requirements.
These are the main features of a twin-screw extruder. The twin-screw extruder has a wide range of applications and is a multifunctional machine. The gear box of our twin-screw extruder is equipped with independent lubricating oil and cooling system and low noise design. In terms of maintenance, it does not require an excessive cost.
Twin-screw extruders can be used to blend and extrude thermosetting plastics such as phenolic resins, epoxy resins, and powder coatings. Besides, It can be used for antistatic masterbatches, alloys, coloring, low-fill co-mingling granulation. In addition, there are high-filled material granulation, cable material granulation, such as sheathing material, insulation material.
Through the above description, we believe you have a certain understanding of the working principle and characteristics of twin-screw extruders and their applications. The twin-screw extruder is developed on the basis of the single-screw extruder, which is now commonly used in all major fields due to its better feeding performance, mixing and plasticizing performance, and stable exhaust performance.
