GN Separation has recently proudly announced the successful completion of factory trial runs for its newest batch of High-Frequency Fine Vibrating Screens. The order, consisting of the GNFG1440 model, is now ready for shipment to a major overseas client, where these screens will play a crucial role in supporting onsite operations.

Design: The Foundation of Performance - The GNFG1440 Model

The GNFG1440 High-Frequency Fine Vibrating Screen is primarily designed for wet screening and dewatering applications. Powered by two long-stroke vibration motors, the equipment employs a reverse self-synchronization principle to generate precise, high-frequency vibrations. This innovative design ensures a linear motion path, facilitating optimal material stratification and significantly enhancing screening efficiency for fine-grained particles. With its compact yet sturdy construction, the GNFG1440 is perfectly suited for industries that demand high throughput and accuracy, such as mining, coal preparation, and metallurgy.

Key Features and Technological Innovations

1. Superior Structural Integrity with Q245R Steel

The screen deck of the GNFG1440 is crafted from Q245R high-strength steel, a material known for its excellent weldability and durability, surpassing that of conventional Q235 steel. After assembly, the entire screen box undergoes stress-relief heat treatment, effectively eliminating residual welding stresses and minimizing the risk of deformation. This process guarantees long-term structural stability, even under continuous heavy-duty use.

2. Reliable Performance with International-Brand Vibration Motors

To ensure consistent and reliable performance, GN Separation has equipped the GNFG1440 with world-class vibration motors sourced from leading manufacturers. These motors are engineered for low-maintenance operation, reducing downtime and lowering lifecycle costs.

3. Long-Lasting Protection with Polyurea Coating

The screen deck is protected by a polyurea spray coating, renowned for its exceptional resistance to chemicals, moisture, and abrasion. This coating significantly extends the equipment's service life compared to traditional paints or epoxy resins, ensuring reliable performance in corrosive environments such as coal slurry processing or mineral tailings handling.

4. Easy Maintenance with Modular Screen Frame and Polyurethane Flexible Screen Mesh

The GNFG1440 features a multi-segment screen deck that simplifies maintenance and screen mesh replacement. Its design accommodates polyurethane flexible screen meshes, which offer superior durability and elasticity compared to metal screens. Additionally, the frame supports optional spray pipe assemblies for automated screen cleaning, preventing clogging and maintaining optimal screening efficiency.

5. Smooth Material Flow with Buffer-Enhanced Feed Box

The equipment's feed box adopts a modular design with multiple integrated buffer plates. These plates dissipate the kinetic energy of incoming materials, reducing impact stress on the screen surface and extending component lifespan. A rubber-lined interior further protects the feed box from wear, minimizing the need for frequent repairs.

Diverse Applications in Wet Processing Industries

The High-Frequency Fine Vibrating Screen is engineered to excel in a variety of wet screening, classification, and dewatering tasks across multiple sectors:

• Mineral Processing: Efficiently separates fine ore particles in gold, copper, and iron ore beneficiation plants.
• Coal Preparation: Dewaters coal slurry to produce clean, market-ready coal products while minimizing water content.
• Metallurgical Industries: Classifies and dewaters tailings, reducing environmental impact and enabling water recycling.
• Chemical and Construction Materials: Processes quartz sand, limestone, and other fine-grained materials with precision.
