Key Features of the GN High Shear Circular Screen

1. Single Excitation Source: The screen operates with a single vibration motor as the excitation source, providing stable and reliable circular motion for the screen deck. This unique vibration mode ensures high screening efficiency and large processing capacity.

2. Large Screening Area: The GN High Shear Circular Screen is designed with a large screening area, arranged in a single layer and multiple sections. This increases the material throughput, improving performance and operational cost-effectiveness.

3. Adjustable Screen Deck Angle: The angle of the screen deck can be easily adjusted for optimal screening results, depending on the material being processed.

4. Energy-Efficient and Compact Design: The circular screen uses less power while delivering exceptional results. Its compact design allows for easy installation in tight spaces, making it a versatile tool for many industries.

5. Durable and Long-Lasting: The screen box assembly is heat-treated for long-term operation under high vibration intensity. Its flexible polyurethane fine screen mesh offers a high opening rate (28-45%) with a lifespan exceeding six months, ensuring durability and reduced maintenance costs.

6. Reliable Components: GN Separation uses imported vibration motors from Martin or OLI, ensuring reliable operation. Additionally, the electrical components are sourced from international brands like Siemens or Schneider, providing high operational safety and longevity.
