Unveiling the GN Large Flip-Flow Vibrating Screen: A Game Changer in Material Screening

At GN Separation, we continually push the boundaries of innovation to deliver solutions that meet the complex needs of industries worldwide. Today, we’re excited to introduce one of our products—the GN Large Flip-Flow Vibrating Screen. This powerful screening solution is designed to handle the most challenging materials, offering unparalleled efficiency and performance.

What Makes the GN Large Flip-Flow Vibrating Screen Stand Out?

The GN Large Flip-Flow Vibrating Screen is a sophisticated piece of machinery engineered to optimize the screening process. Its primary components include a box-type exciter, main vibrating screen frame, floating screen frame, shear spring, damping spring, flexible polyurethane screen mesh, support, and driving device. What sets this equipment apart is its linear running amplitude, making it exceptionally effective in various applications.

Key Features:

  • Double Mass Near Resonance Principle: The Flip-Flow Vibrating Screen operates on the double mass near resonance principle, which gives the floating screen frame a large amplitude. This allows the screen surface to deliver material with an acceleration of up to 50 G, ensuring thorough and efficient screening even for difficult materials.
  • Versatile Application: This screen is particularly suited for dry screening of medium to fine-grained, wet, sticky, and other hard-to-screen materials. The design prevents clogging, enhancing the screening efficiency significantly.
  • Robust Design: The screen machine wallboard is made from high-strength alloy steel, with Huck rivets used for hydraulic tension assembly, eliminating welding residual stress. The crossbeam under the screen utilizes a rectangular tube design, while the lightweight, high-strength exciting beam box structure ensures durability and longevity.
  • Customizable Amplitude: The amplitude of the floating screen frame can be adjusted by altering the number of shear springs, allowing for fine-tuning based on the material being processed.
  • Efficient Exciter: The high-efficiency helical gear box-type exciter provides substantial exciting force with ultra-low noise, stable operation, and a long service life. The eccentric block outside the exciter box enables easy adjustment of the amplitude.

Model Options to Meet Various Needs

The GN Large Flip-Flow Vibrating Screen comes in several models, including the GNFS2461, GNFS3061, GNFS3085, GNFS3673, GNFS3690, and GNFS43100, each offering different screen areas, power, and capacities to suit diverse industrial needs. For instance, the GNFS43100 model provides a screen area of 43 square meters and can handle capacities up to 950 tons per hour.

For more demanding applications, GN Separation also offers double-deck models like the GNFD2461 and GNFD43100, which double the screen area and enhance capacity, making them ideal for heavy-duty operations.

Advanced Design for Superior Performance

Our engineers have meticulously optimized the structure and vibration parameters of the GN Large Flip-Flow Vibrating Screen using finite element analysis. This approach helps avoid natural frequencies at all levels of the screen, reducing the risk of resonance and extending the machine’s service life.

The screen’s flexible polyurethane mesh is installed using a pressing method, simplifying the replacement process. The mesh’s elastic deformation provides a self-cleaning function, effectively preventing clogging, especially with fine, wet, and viscous materials.

The Science Behind the Flip-Flow Vibrating Screen

The working principle of the Flip-Flow Vibrating Screen revolves around double mass near resonance, where a single drive generates double vibrations. The main vibrating screen frame, driven by exciting force, performs basic vibrations. Meanwhile, the floating screen frame and the main vibrating screen frame are connected via a shear spring, moving relative to each other in a near-resonance state.

This relative movement causes the polyurethane screen mesh to stretch and relax continuously, generating a high acceleration that fully throws up and layers the material, ensuring effective screening. The screen can transmit up to 50 G of acceleration to the material, loosening it and ensuring it passes through the screen for efficient separation.

Conclusion

The GN Large Flip-Flow Vibrating Screen is more than just a piece of equipment—it’s a solution to some of the toughest screening challenges faced by industries today. Whether you’re dealing with sticky, wet materials or fine particles that are difficult to screen, this advanced vibrating screen is designed to deliver exceptional performance and durability.
