Low-Speed Pelletizing Technology: Energy-Saving And Efficient Processing

The low-speed waste plastic film pelletizer production line adopts the leading low-speed pelletizing technology, which has significant advantages over the traditional high-speed pelletizer. The low-speed pelletizing technology operates at a lower speed, effectively reducing mechanical wear, prolonging the equipment’s service life, and reducing energy consumption.

Energy saving and environmental protection

  • The low-speed pelletizer adopts DC variable speed control technology, which can adjust the rotational speed according to the actual production demand, avoiding the waste of electric energy. In addition, low-speed operation reduces friction and heat generation, further reducing energy consumption and carbon dioxide emissions, which aligns with the green production concept.

Excellent granule quality

  • The slow rotation of the low-speed pelletizer provides sufficient residence time for the melt to ensure full plasticization and uniform mixing of the plastic pellets. At the same time, low-speed operation reduces shear and heat stress, avoiding pellet degradation and thus improving pellet quality and strength.

Highly adaptable to processing

  • Low-speed pelletizing technology is suitable for a wide range of low melting point plastic wastes, including polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET). By adjusting the screw design and process parameters, the low-speed pelletizer can be adapted to the characteristics of different wastes to achieve efficient and stable pelletizing production.


Pretreatment Of Used Films: Optimizing Recycling Efficiency

In the granulation process of used plastic films, the pretreatment step is crucial, as it determines the recycling efficiency and the quality of the subsequent granulation. To optimize the recycling solution, experts recommend the following pretreatment measures for film characteristics:

Classification and Sorting

  • The sorting and packaging of waste film are based on characteristics such as film type, thickness, color, etc. This helps to improve the quality of subsequent pelletizing. This helps to improve the quality and efficiency of subsequent granulation and avoid interactions between different film materials.

Cleaning and Dewatering

  • Remove surface contaminants, such as grease, dust, paper, etc., from the waste film. Water or chemical washing is used to thoroughly remove these impurities and improve the purity of the film to provide clean raw materials for subsequent pelletizing.

Crushing and shredding

  • After sorting, the waste film is crushed into smaller pieces or powder. The degree of crushing depends on the requirements of the pelletizing equipment. Smaller particle sizes are conducive to improved pelletizing efficiency and quality.

Metal sorting

  • The waste film may present metal impurities like bottle caps, zippers, etc. Metal sorting equipment is used to remove these metals to prevent them from damaging the pelletizing equipment or affecting the quality of the pellets.

Drying and deodorizing

  • The crushed or pulverized film material is dried to remove moisture. The drying process prevents water vapor from being generated during the pelletizing process, which can affect the formation and quality of the pellets. In addition, deodorization equipment removes odors from the film to ensure the pellets have a good sensory quality.

By implementing these pre-processing measures, we can effectively improve the efficiency of waste film recycling, provide high-quality raw materials for subsequent pelletizing, and ensure the quality and value of the pellets.


Low-Speed Waste Plastic Film Pelletizer Production Line: Customized Solutions

The recycling characteristics of used plastic film vary greatly, so customized solutions are required for efficient processing. Low-speed used plastic film granulator production lines can be customized to meet specific needs based on film type, contamination level, and output requirements.

The key to a customized line is a thorough understanding of the characteristics of the film material and the desired output goals. Based on the results, specialized pelletizer line providers will carefully evaluate film composition, thickness, and contamination and recommend the most appropriate machine configuration and processing parameters.

  • Film Pretreatment: Film pretreatment equipment, such as crushers and washers, can be customized according to the level of film contamination to optimize the pelletizing process and ensure granule quality.
  • Pelletizing equipment: The parameters of the pelletizer, such as aspect ratio, screw design, and heating system, can be adjusted according to the melt flow characteristics of the film and the output requirements.
  • Post-processing technology: Post-processing equipment, such as cooling machines, pelletizers, and packaging machines, can be customized according to the specifications of the pellets and packaging requirements to achieve automated production and high-quality pellets.

Through customized line design, low-speed pelletizing technology can optimize the efficiency and economy of film recycling and produce high-quality pellets that meet specific application requirements.

Operational optimization of a low-speed used plastic film granulator production line

Key Operational Parameters

The operational efficiency of a low-speed pelletizer line depends on the optimization of several critical operating parameters, including:

  • Feed Rate: Controls the rate at which waste film enters the pelletizer to avoid overloading or undersupply.
  • Screw Speed: Adjusts the speed of screw rotation to control the efficiency of plastic melting and mixing.
  • Temperature Setting: Manage the temperature of each area of the pelletizer to ensure uniform melting and pelletizing of plastic.
  • Cooling Water Temperature: Controls the temperature of the cooling water flowing through the pelletizing head to cool and solidify the plastic pellets.
  • Cutter Speed: Adjusts the cutter’s rotation speed to control the pellets’ size and uniformity.
  • Data Monitoring and Control: Continuous monitoring and control of these operating parameters is essential to ensure stable line operation and high-quality pellets. Advanced control systems allow real-time monitoring and adjustment to optimize production parameters and maximize output.
  • Preventive Maintenance: Regular maintenance is the key to keeping the production line running efficiently. Equipment should be inspected and lubricated, and consumables should be replaced according to the manufacturer’s recommendations. Preventive maintenance helps prevent equipment breakdowns and delays and extends the line’s life.
  • Operator Training: Qualified operators are critical to successfully operating a low-speed pelletizer line. They should be thoroughly trained to understand the production process, operational controls, and equipment maintenance. Well-trained operators can quickly respond to production problems and keep the line running smoothly.


Post-processing technology: ensuring high-quality particles

Post-processing technology in a low-speed used plastic film pelletizer line is essential to ensure high-quality pellets. A proper post-processing procedure removes impurities, moisture, and odor from the pellets, increasing the availability and market value.

Key post-processing steps:

  • Secado: Removes moisture from the pellets to prevent problems during subsequent processing.
  • Sorting: Sorting the pellets according to size, shape, and density to meet specific quality standards.
  • Deodorization: removing odors from the pellets to make them suitable for various applications.

The choice of post-processing equipment depends on the type of waste plastic film, the pelletizer specifications, and the pellets’ expected quality. Professional granulator manufacturers can provide customized reprocessing solutions to meet specific customer requirements.

Types of post-processing equipment:

  • Centrifugal Dehydrator: Removes water from the pellets by centrifugal force.
  • Vibratory Sieve: Sorts particles according to size and shape.
  • Hot Air Dryer: Hot air is removed from the pellets using the Deodorizing towers. Remove odors from the pellets by air or water flow.

Optimizing the finishing process improves the quality of the pellets and extends the life of the granulator. By investing in high-quality post-processing equipment and implementing best practices, companies can realize the total value of recycling used plastic film.
