GN Separation is proud to announce the successful shipment of one of our large model dewatering decanter centrifuges, the GNLW654-VFD, to an overseas client for industrial sludge treatment. This delivery highlights the increasing global demand for GN's high-performance separation equipment and showcases our technical expertise in providing efficient, reliable, and energy-saving solid-liquid separation solutions.

Powerful Performance for Demanding Applications

The GNLW654-VFD is part of GN’s T Series dewatering decanter centrifuges, engineered with an optimized beach angle of 8.5 degrees to enhance dewatering efficiency and discharge drier solids. This model is specifically designed to handle materials with large particle size, high solid-liquid density difference, high concentration, and low viscosity, making it ideal for municipal and industrial wastewater, oily sludge, drilling mud, chemical wastewater, sand washing water, and more.

Key Features of the GNLW654-VFD

• Large Bowl Design: With a 650 mm (25.6 inch) bowl diameter and 2730 mm (107.5 inch) length, the GNLW654 offers high throughput capacity and effective sludge dewatering performance.

• High G-Force: Operating at a max speed of 2873 RPM, this model generates a G-force up to 3000G, facilitating rapid and thorough separation.

• Premium Materials: The bowl and screw are made of duplex stainless steel (SUS2304 or SUS2205) through centrifugal casting, offering superior corrosion and wear resistance compared to conventional SS304 or SS316.

• Energy-Efficient & Low Noise: The design includes a deep liquid pool, optimized cone angle, and anti-turbulence structures, contributing to better clarity, reduced energy consumption, and quieter operation.

• Wear Protection: The solids discharge ports and screw flights are protected with tungsten carbide sleeves and replaceable wear-resistant tiles, ensuring long service life even under harsh working conditions.

• Smart Control: Equipped with a VFD+PLC+HMI control panel, the centrifuge allows real-time monitoring of vibration, temperature, torque, and lubrication status. Emergency protocols such as automatic plugging and shutdown procedures are in place for safe operation.

• Space-Saving Layout: Both motors are installed at one end of the unit for compact design and easier maintenance access.

Reliable Dewatering for a Wide Range of Materials

GN’s T Series decanter centrifuges are versatile and widely applied in industries such as:

• Municipal wastewater and sludge treatment

• Oilfield drilling fluids and oily sludge recovery

• Sand and mineral washing

• Steel-making and precision casting wastewater

• River and lake dredging

• Chemical, pharmaceutical, and food industry wastewater

• Salt and kaolin recovery

• Biomass, aquaculture, and more

For materials with fine particles, GN also recommends using flocculants to enhance solid aggregation before centrifugation, enabling more efficient separation.

GN Separation has recently achieved a significant milestone by successfully completing the assembly and rigorous factory testing of a mud dewatering centrifuge package tailored for engineering slurry applications. This comprehensive system, featuring a GN-engineered Decanter Centrifuge Model GNLW654-VFD and a complementary three-chamber flocculant dosing unit Model GNSJY2000, is scheduled for shipment to an international client in the near future.

The Decanter Centrifuge GNLW654-VFD is meticulously crafted to manage the substantial volumes of muddy mixtures generated in tunnel boring machine (TBM) operations, river and lake dredging projects, and hydraulic excavation endeavors. These processes yield considerable amounts of water-laden sludge, necessitating specialized machinery for efficient solid-liquid separation. The GNLW654-VFD model stands out in this domain, offering robust processing capabilities that meet the stringent requirements of large-scale engineering projects.

A pivotal attribute of the GNLW654-VFD is its Variable Frequency Drive (VFD) control panel, which offers unmatched adaptability in operational settings. This sophisticated control system empowers operators to dynamically adjust the centrifuge's rotational speed based on the unique properties of the incoming slurry and the targeted processing results. By fine-tuning the centrifuge's performance in real-time, the VFD technology guarantees optimal efficiency and effectiveness in separating solids from liquids, even amidst fluctuating conditions.

In conjunction with the centrifuge, the GNSJY2000 automatic polymer dosing unit plays a crucial role in enhancing the separation process. This three-chamber system is expertly designed to precisely formulate and dispense flocculant chemicals, which are instrumental in aggregating fine particles within the slurry. By effectively binding these microscopic particles together, the flocculant streamlines their removal during the centrifugation process. The GNSJY2000's integrated dosing pump ensures precise and consistent delivery of the flocculant, directly introducing it into the centrifuge to maximize the capture and separation of fine particles. This leads to a purer, more manageable solid output and a marked improvement in separation efficiency.

The triumphant conclusion of factory testing for the GN Decanter Centrifuge GNLW654-VFD and GNSJY2000 automatic flocculant dosing unit underscores GN Separation's engineering expertise and dedication to environmental responsibility. As the company gears up to dispatch this package to its overseas client, it remains steadfast in its mission to deliver solutions that foster sustainable advancement in the engineering and environmental realms.
