In the plastic recycling industry, the choice of plastic pelletizing system has a crucial impact on the quality and production efficiency of the final product. Common granulation systems include strand pelletizing systems and water ring pelletizing systems, each of which is suitable for different material and process requirements.
This article will provide a brief analysis of the principles, applicable materials, and respective advantages of two granulation systems to help companies choose the most suitable plastic pelletizing system.
Strand Pelletizing System
The strand pelletizer extrudes molten plastic strips from the die, cools them in a water tank, and then cuts the cooled strips into granules using a pellet cutter machine.
This system is mainly suitable for processing harder and less deformable plastic materials such as PP, PE, PET, etc., especially for materials that require longer cooling times during the granulation process.
Advantages of Strand Type Pelletizing
- Simple operation: The entire process of strand pelletizing is intuitive, making it easy to monitor and adjust during production.
- Wide application range: It is suitable for handling various common thermoplastics, with particularly good results in processing rigid materials.
- Uniform pellets: The water-cooling process ensures that the final pellets are uniformly shaped, making them ideal for high-quality plastic pellet production.
Water-ring Pelletizing System
The water ring pelletizing system uses high-pressure water at the die head to cool and cut the molten plastic directly into pellets.
This plastic pelletizing system is often used for materials with high melting temperatures and low melt viscosity, such as LDPE, LLDPE, and EVA. It can quickly form pellets without the need for extended cooling.
Advantages of Water-ring Pelletizing
- Efficient production: The water ring pelletizing system quickly cools and cuts pellets, reducing cooling time, and making it suitable for large-scale and high-efficiency production needs.
- High automation: The water ring granulation synchronizes cooling and pelletizing, simplifying the process, reducing operational difficulty, and enhancing automation levels.
- Stable production: continuous running without the risk of strand-breaking.
Choosing the Right Plastic Pelletizing System
The strand pelletizing system and the water ring pelletizing system each have their advantages and are suitable for different plastic materials and production needs. By thoroughly understanding the characteristics of these two systems, businesses can make an informed decision based on their specific requirements, ensuring a smooth production process and high-quality final products.
