How to choose the pelletizing method of twin-screw extruder?
Twin-screw extruder is currently one of the most common equipment in the field of plastics processing, which is widely used in the production process of plastic products. In the operation of twin-screw extruder, it is especially important to choose the right pelletizing method. Today, we will introduce you to several common pelletizing methods: water ring pelletizing system, underwater pelletizing system, pull-strip underwater pelletizing system, die face hot cutting pelletizing system, water pull-strip pelletizing system, and air-cooled pull-strip pelletizing system, to help you in the choice of a more comfortable.
The water ring cutting pelletizing system has received a lot of attention for its high efficiency and environmental friendly features. The system cuts the extruded plastic strips into required pellets through water ring cutting, and then sends the pellets to the next process through the hydraulic conveying system. Its stable operation and low energy consumption make it suitable for high-volume processing needs.
Underwater cutting pelletizing system is suitable for the pelletizing process which requires high precision. With the help of underwater cutting technology, it cuts the extrudate into uniform pellets and transmits them to the subsequent process through hydrodynamic transmission. This system has the advantages of high cutting precision and uniform particle size, and is suitable for the demanding processing of plastic products.
The pull-strip underwater pelletizing system is an innovative solution that combines pull-strip technology and underwater cutting technology. The system forms the plastic extrudate into long blanks by means of pulling strips, and then cuts the blanks into the required pellet shapes by means of underwater cutting. This type of pelletizing ensures pellet uniformity while providing greater flexibility in meeting the needs of different pellet shapes
The Die Face Hot Cut Pelletizing System rapidly cuts extrudates into desired pellets by means of hot die face cutting technology. This system is easy to operate, can be applied to various shapes of pelletizing needs, and the cutting effect is stable, which is a kind of high-efficiency pelletizing method.
The water puller pelletizing system introduces water cooling on the basis of the traditional puller technology, which can realize rapid pelletizing. The system mechanically pulls the extrudate flat and cuts it into pellets, which are then cooled by a water cooling system. This type of pelletizing is flexible and suitable for the preparation of pellets of different sizes and shapes.
The air-cooled drawbar pelletizing system has attracted much attention for its high efficiency and low energy consumption. The system cools the extrudate and cuts it into pellets by means of air-cooling, which is easy to operate, eliminates the need for a water cooling system, and is suitable for pelletizing different materials and shapes.
When choosing the pelletizing method of twin-screw extruder, it is necessary to make comprehensive consideration according to different production requirements and product characteristics. The above introduction of several types of pelletizing methods have their own characteristics, and I hope to help you better choose a suitable pelletizing method. Let us work together to create more fine and beautiful plastic products!
