Double column non-stop screen changer: an efficient choice for plastic recycling granulation
Double column non-stop screen changers are indeed an efficient choice for plastic recycling granulation processes. Here’s why:
Efficiency and Continuity
Non-Stop Operation: As the name suggests, double column non-stop screen changers allow for continuous operation without the need to stop the production line to change the screen. This significantly enhances productivity and reduces downtime.
Alternate Working Mode: These screen changers typically feature an alternate working mode, where one screen is active while the other is being prepared for use. This ensures a seamless transition between screens, maintaining a continuous and stable material flow.

Technical Advantages
Advanced Pressure Seal Technology: Double column non-stop screen changers adopt advanced pressure seal technology. This technology uses the pressure of the polymers to drive seal components, achieving an optimal sealing effect and allowing for quicker screen changes.
High-Quality Materials: Constructed from high-grade alloy steel that has undergone a nitriding process, these screen changers exhibit extended lifespans and durability.
Rheological Optimization: The honeycomb panel of these screen changers is optimized to reduce fluid shear during the extrusion process, which can improve the quality of the recycled plastic granules.
Modular Design and Versatility
Modular Combination Mode: The modular design of double column non-stop screen changers makes them suitable for different standard extruders. This versatility allows them to be easily integrated into various plastic recycling granulation lines.
Easy to Clean and Maintain: The modular design also facilitates easy cleaning and maintenance, which is crucial for maintaining the efficiency and longevity of the equipment.

Application in Plastic Recycling Granulation
Wide Range of Materials: Double column non-stop screen changers can handle a wide range of plastic materials, including PP, PE, PS, ABS, PET, and more. This makes them ideal for recycling a variety of plastic waste.
Improved Product Quality: By ensuring a continuous and stable material flow, these screen changers contribute to the production of high-quality recycled plastic granules. These granules can be used in various applications, such as manufacturing new plastic products or as raw materials for other processes.

In summary, double column non-stop hydraulic screen changers offer a combination of efficiency, technical advantages, modular design, and versatility that makes them an excellent choice for plastic recycling granulation processes. They help to reduce downtime, improve productivity, and enhance the quality of recycled plastic granules. As such, they are a valuable addition to any plastic recycling operation looking to optimize its processes and improve its output.
