GN Separation, a global leader in industrial separation, will be exhibiting at the 26th IE expo China, which will be held April 21-23, 2025 at the Shanghai New International Expo Center (SNIEC). As Asia's premier environmental technology event, the show will attract more than 2,500 exhibitors and 100,000 professional visitors, and GN Separation will bring its three core separation equipment - full hydraulic centrifuge, three-phase decanter centrifuge, and solids vacuum pump - to showcase its industry-leading technology and green solutions. Green solutions.

Fully hydraulic centrifuge: a new benchmark for high-efficiency solid-liquid separation
Breaking through the limitations of traditional mechanical drive, GN fully hydraulic centrifuge realizes compact design and low-maintenance operation through innovative hydraulic system. Its core advantage lies in the stepless speed control technology, which can precisely regulate the speed to suit complex materials with different solid contents (such as high-viscosity slurries or thin suspensions), ensuring separation efficiency while significantly reducing energy consumption. This technology is particularly suitable for the chemical, mining and environmental protection sectors, providing a flexible solution for industrial scenarios where multi-phase mixtures are handled.

Three-phase decanter centrifuge: three-phase separation in one machine
Equipped with patented centripetal pump technology, the three-phase decanter centrifuge separates light and heavy liquids and solids in a single continuous process by means of ultra-strong centrifugal force, completely overturning the multi-phase separation model. Its application scenarios cover:

Oil and gas industry: efficient separation of oil, water and rock chips in drilling fluid;
Biofuel industry: extraction of glycerol, methanol and separation of biomass residue;
Chemical manufacturing: purification of solvents and catalyst recovery.
This equipment helps companies realize cost reduction and efficiency by reducing the space occupied by the equipment and operating costs.
Solid vacuum pumps: all-round material handling innovators
Designed on the fully pneumatic conveying principle, the solids vacuum pump can flexibly handle a wide range of materials from low-solid slurries to high-solid suspensions, powders and even gravel. Its modular design supports rapid adaptation to different working conditions, significantly improving production efficiency. In the building materials, food and environmental protection sectors, the pumps are the preferred choice for material handling due to their stability and low maintenance costs.

GN Synergistic Frequency Vibrating Screen is a self-developed, high-performance screening machine that integrates linear vibration frequency and partial electromagnetic vibration frequency to enhance efficiency and accuracy. Designed for screening, grading, and separation of fine-grained materials, this advanced vibrating screen is widely used in industries such as coal processing, metallurgical mineral processing, chemical production, and ceramics.

GN Separation Company, a renowned expert in solid-liquid separation solutions, successfully concluded the factory assembly of a comprehensive tailings dewatering centrifuge system tailored for a mining company in South America. The system's core component, the GNLW764-VFD Dewatering Centrifuge, is ready for transportation and installation at the client's site.

The GNLW764-VFD Dewatering Centrifuge is specifically engineered for efficient solid-liquid separation of tailings slurries. Tailings, the residual materials left after ore processing, often contain substantial amounts of water that must be removed before disposal or further utilization. The advanced variable frequency drive (VFD) technology integrated into the GNLW764-VFD offers unparalleled control over the dewatering process, ensuring optimal performance and reliability.

Dewatering centrifuges play a pivotal role in the mining industry, particularly in processing tailings. These machines leverage centrifugal force to separate solid particles from the liquid phase. Tailings slurry is fed into the rotating centrifuge bowl, where the centrifugal force pushes the heavier solid particles towards the bowl's wall, forming a cake that is continuously scraped off and discharged. The clarified liquid, known as filtrate, is collected and can be reused or disposed of as per regulatory requirements.

One of the key advantages of dewatering centrifuges in tailings dewatering is their ability to handle slurries with high solids content. Unlike other separation techniques, such as filtration or settlement, centrifuges can achieve a much higher solids concentration in the cake, thereby reducing waste volume and lowering transportation and disposal costs. Furthermore, the continuous nature of the process allows for higher throughput and productivity.

The GNLW764-VFD Dewatering Centrifuge stands out due to its integration of VFD technology, which enables precise control over the centrifuge bowl's rotational speed. This adaptability ensures high efficiency, reduces energy consumption, and minimizes wear and tear on the equipment. Additionally, the VFD provides a soft start and stop function, minimizing mechanical stress and prolonging the machine's lifespan.

The GNLW764-VFD Dewatering Centrifuge operates in synergy with the GNSJY-6000 Chemical Dosing Unit to enhance the overall efficiency of the tailings dewatering process. The Chemical Dosing Unit prepares and doses flocculants, chemicals that promote the aggregation of solid particles in the slurry, making them easier to separate.

The tailings dewatering system also includes a centrifuge support skid frame, designed to securely install and support the GNLW764-VFD Dewatering Centrifuge, ensuring safe operation and minimizing the risk of accidents or damage. The system features a tailings receiving tank that serves as a buffer for incoming tailings slurry, ensuring a continuous supply to the dewatering centrifuge. A screw pump, strategically positioned between the receiving tank and the centrifuge, ensures optimal slurry feeding rates, maintaining consistent performance and efficiency.

With the factory assembly completed, GN Separation is now preparing for the transportation and installation of the tailings dewatering system at the client's site in South America. The system is expected to significantly enhance the client's tailings dewatering capabilities, improving productivity, reducing costs, and minimizing environmental impact. GN Separation remains dedicated to providing innovative solutions for the mining industry, helping clients worldwide achieve sustainable and profitable operations.
