GN Separation Equipment Manufacturer

GN Separation has recently announced the successful completion of factory trial runs for its latest batch of High-Frequency Fine Vibrating Screen. The order, featuring the model of GNFG1440, is now set for shipment to a key client overseas, where it will support critical operations onsite.

Design Drives Performance: The GNFG1440 Model
The GNFG1440 High-Frequency Fine Vibrating Screen is mainly used in wet screening and dewatering technology. Powered by two long-stroke vibration motors, the equipment utilizes a reverse self-synchronization principle to generate precise, high-frequency vibrations. This design ensures a linear motion trajectory, optimizing material stratification and enhancing screening efficiency for fine-grained particles. The model’s compact yet robust structure makes it ideal for applications requiring high throughput and accuracy in industries such as mining, coal preparation, and metallurgy.

Key Features and Technological Advancements
1. Enhanced Structural Integrity with Q245R Steel
The GNFG1440’s screen deck is constructed from Q245R high-strength steel, a material renowned for its superior weldability and durability compared to conventional Q235 steel. After assembly, the entire screen box undergoes stress-relief heat treatment, eliminating residual welding stresses and minimizing deformation risks. This process ensures long-term structural stability, even under continuous heavy-duty operation.
2. International-Brand Vibration Motors for Reliability
To guarantee consistent 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 lifecycle costs.
3. Polyurea Coating for Corrosion and Wear Resistance
The screen deck is protected by a polyurea spray coating, a material known for its exceptional resistance to chemicals, moisture, and abrasion. This coating extends the equipment’s service life significantly compared to traditional paints or epoxy resins, ensuring reliable performance in corrosive environments such as coal slurry processing or mineral tailings handling.
4. Modular Screen Frame with 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 meshs, 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. Buffer-Enhanced Feed Box for Smooth Material Flow
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.

Versatile Applications in Wet Processing Industries
The High Frequency Fine Vibrating Screen is engineered to excel in wet screening, classification, and dewatering tasks across diverse 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.
