Let's delve deeper into the intricacies of this remarkable machinery.

Introduction to GN Large Linear Vibrating Screen

The GN Large Linear Vibrating Screen is a sophisticated piece of equipment that integrates advanced technology with robust construction. Its core components include a box-type vibration exciter, a sturdy screen box, vibration damping springs, a supportive structure, and a driving device. The unique design ensures that the machine operates with a linear amplitude track, allowing for precise and efficient screening processes.

This versatile screen can be configured horizontally or at an inclined angle, catering to the specific requirements of different industrial processes. Its widespread adoption underscores its ability to handle wet classification, dewatering, demineralization, tailings dry discharge, and numerous other critical process links.

Screen Surface Structure and Customization

The GN Large Linear Vibrating Screen offers flexibility in terms of its screen surface structure, which can be configured as either single-layer or double-layer depending on the screening requirements. This design feature ensures that the machine can be tailored to suit a variety of materials and particle sizes.

Moreover, the model of the screen unit can be customized according to customer specifications. This level of customization ensures that each installation is optimized for maximum performance and efficiency, meeting the unique needs of each industrial application.

Working Principle

The GN Large Linear Vibrating Screen operates on a well-established and highly effective principle. Here's a step-by-step breakdown of its working mechanism:

Forced Synchronization: Equipped with two gearbox vibrators, the screen body is driven to move back and forth in a linear motion. This movement is achieved through the principle of forced synchronization, ensuring smooth and consistent vibration.

Synchronous Vibration: Under the influence of the exciting force generated by the vibrators, the screen surface vibrates synchronously. This vibration is transmitted to the materials placed on the screen, causing them to be thrown up and layered on the screen surface.

Screening and Grading: As the materials are impacted and thrown up, they are screened and graded according to their specified particle sizes. The continuous buffering and input of materials from the feeding trough to the receiving plate ensure a seamless screening process.

Material Discharge: The screened materials are then discharged into separate receiving troughs located above and below the screen surface. This separation facilitates the easy transfer of materials to the next process link.

Adjustable Inclination Angle: The included angle between the direction of the exciting force and the horizontal plane can be designed specifically for the materials being processed. This angle plays a crucial role in determining the running speed of the materials on the screen surface and, consequently, the overall processing capacity of the equipment.

The GN Large Linear Vibrating Screen is a testament to the fusion of advanced technology and robust engineering from GN Separation. Its versatility, precision, and customization options make it an invaluable asset for industries that rely on efficient and reliable screening processes. Whether it's mineral processing, coal preparation, or gravel aggregate production, this machine consistently delivers outstanding performance, ensuring that materials are screened and graded to the highest standards.

GN proudly present: Classification Vibrating Screen. Extensively utilized in the classification and screening of various materials, including iron ore, coal, non-ferrous metal ore, building materials, and products from the chemical industry, this equipment incorporates advanced design techniques, such as finite element analysis and anti-fatigue analysis, to ensure a reasonable structure, low energy consumption, and a substantial screening and classification capacity. It is adept at functioning in diverse working conditions that are prone to corrosion and wear, demonstrating large processing capacity, high efficiency, and stable performance. Notably, the size of the screen machine can be customized to meet specific customer requirements.

Equipped with two vibrating motors, the GN Classification Vibrating Screen operates by utilizing the principle of reverse self-synchronization, enabling the screen body to move in a linear line. The screen body drives the screen panel to vibrate synchronously, transmitting force to the materials on the panel. This action impacts the materials, causing them to be thrown up on the screen surface for layering. Subsequently, the materials are graded according to the specified particle size as they pass through the screen.

The GN Classification Vibrating Screen boasts several notable features:

Advanced Wallboard Design: The wallboard is not welded. Instead, it is constructed using a steel plate with enhanced impact toughness and cold bending properties. It is assembled using imported HUCK rivets for hydraulic tension, eliminating welding residual stress and material defects. This design prevents the reduction of fatigue strength in the wallboard due to such defects.

Optimized Structural Strength: Through finite element analysis, the structural strength and vibration quality of the screen machine are optimized to the fullest extent, reducing stress and prolonging the equipment's service life.

Durable Fluids-Touching and Wear Parts: The fluids-touching parts and easily worn components are sprayed with polyurea using a spraying machine imported from the United States. This coating is corrosion-resistant, erosion-resistant, and wear-resistant.

Effective Post-Weld Treatment: The main components undergo a post-weld heat treatment process, which effectively eliminates welding stress.

Product Serialization and Modular Design: The product is serialized to meet manufacturing requirements under different process conditions. The polyurethane screen panel is modular, providing versatility and convenience during replacement.

Adjustable Installation Angle: The whole machine is installed at a positive inclination angle, with the installation angle adjustable up to 4 degrees. This adaptability suits the requirements of different process materials.

Optimized Screen Surface Design: The plane design of the entire screen surface facilitates screening and grading materials, maximizing the effective screening area.

Rubber Damping Spring Design: This design offers advantages such as good damping effect, low noise, a small resonance field, good resilience, stable mechanical performance, long service life, and low cost.
