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.

Recently, GN Separation successfully finished manufacturing two sets of GNOST-15 Oil Sludge Treatment Systems (OSTS). These systems are now going through rigorous factory trial assemblies to guarantee top-notch performance before being deployed.

A Holistic Approach to Oil Sludge Treatment

The GNOST-15 oil sludge treatment system consists of seven interconnected modules, each designed to carry out specific functions. Together, they convert toxic oil sludge into reusable resources. The system effectively tackles issues like high solid content, emulsified oils, and varying viscosity, ensuring efficient separation of oil, water, and solids while keeping operational costs and environmental impact to a minimum.

1. Slurry Feed Pump Module: Precise Delivery for Continuous Processing

The slurry feed pump module marks the starting point of the system, transporting raw oil sludge into the treatment sequence. It is fitted with high-pressure, corrosion-resistant pumps that guarantee a steady flow of material, even in tough conditions.

2. Pre-Mixing Tank Module: Intelligent Conditioning for Better Separation

Raw oil sludge often contains emulsified oils and dense solids that make direct separation difficult. The pre-mixing tank module addresses this by diluting and conditioning the feed through controlled stirring, temperature control, and chemical addition. The integrated steam generator module produces steam to heat the sludge to ideal temperatures (usually 60–80°C), breaking down thick emulsions and improving flow. This step is vital for preparing the sludge for subsequent processes, ensuring higher separation efficiency.

3. Shale Shaker Module: Precise Removal of Large Solids

To shield downstream equipment from damage and blockages, the shale shaker module employs a high-frequency shale shaker to eliminate coarse solids (>2 mm). The shaker is equipped with an anti-splash cover and spray nozzles to prevent material from escaping and ensure uninterrupted operation without manual assistance. This module lightens the load of solids on subsequent centrifuges, extending their lifespan and boosting performance.

4. GNLW-554 Two-Phase Decanter Centrifuge Module: Fine Solid Separation for Cleaner Output

The GNLW-554 two-phase decanter centrifuge is a key part of the system, using centrifugal force (up to 3,000 G) to separate fine solids from liquids. By adding flocculants during operation, the module achieves outstanding solid removal rates (>95%), resulting in an oil-water mixture with reduced solids content. This step is crucial for enhancing the efficiency of the final oil-water separation stage.

5. GNLWS-554 Three-Phase Centrifuge Module: Maximizing Oil Recovery

The GNLWS-554 three-phase centrifuge module stands at the forefront of oil-water-solid separation technology. It uses differential speed control and a sophisticated bowl design to efficiently split the incoming mixture into three streams: recovered oil, treated water, and residual solids. This module not only ensures adherence to environmental standards but also allows clients to recover valuable hydrocarbons, boosting project profitability.

6. Chemical Dosing Module: Tailored Formulations for Peak Performance

Given that oil sludge composition differs greatly across industries, GN Separation's chemical dosing unit enables real-time adjustment of treatment parameters. Operators can prepare and inject demulsifiers, pH adjusters, and flocculants in precise amounts using pumps.

7. Steam Generator Module: Energy-Efficient Heating for Improved Process Efficiency

Heating plays a pivotal role in breaking emulsions and reducing viscosity. The steam generator module generates clean, dry steam to heat the pre-mixing tank and maintain optimal process temperatures.

Factory Trials: Ensuring Dependability in Real-World Scenarios

The two GNOST-15 systems are currently being assembled for factory trials at GN Separation's facility in China.
