GN GNLW364 Dewatering Decanter Centrifuge Applied by Overseas Environmental Protection Company

GN Separation recently delivered its GNLW364 T Series Dewatering Decanter Centrifuge to an overseas environmental protection company, further expanding its global footprint in industrial and municipal sludge treatment. Known for its efficient performance and robust design, the GNLW364 centrifuge is ideally suited for high-demand dewatering applications across various industries.

Optimized for Dewatering Performance

The GNLW364 model belongs to GN’s T Series, a line of decanter centrifuges specifically engineered for dewatering and thickening purposes. Featuring an optimized beach angle of 8.5 degrees, the T Series is designed to extend the drying zone within the bowl, allowing for higher solid dryness and clearer liquid separation.

This series is widely applied for municipal and industrial wastewater sludge, where efficient dewatering and reduced moisture content are critical. For materials containing fine particles and low viscosity, flocculants are typically added to enhance solid-liquid separation performance before processing through the T Series decanter.

Key Features of the GNLW364 T Series Decanter Centrifuge

  • Bowl Diameter: 360 mm

  • Bowl Length: 1520 mm

  • Max Speed: 3964 RPM

  • Max G-force: 3200 G

  • Main Motor Power: 22–37 kW

  • Backdrive Motor Power: 7.5–11 kW

  • Beach Angle: 8.5°

Intelligent and Safe Operation

This unit is equipped with a three-frequency conversion control cabinet — a smart electrical system that allows for independent control of the main motor, backdrive motor, and feed pump. Combined with real-time monitoring sensors for temperature and vibration, the system ensures safe, stable, and efficient operation, even under demanding conditions.

GN also integrates a complete alarm and protection system. If abnormal parameters such as overload, high temperature, or excessive vibration are detected, the machine automatically initiates safety protocols, including switching to plug removal or emergency shutdown procedures.

Durable Materials and High-Quality Construction

To guarantee longevity and performance, the bowl and end caps are made from duplex stainless steel (SUS2205 or SUS2304) via centrifugal casting, which provides superior resistance to corrosion and stress compared to conventional stainless steel grades like SUS304 or SUS316.

The screw conveyor is protected by replaceable tungsten carbide tiles, and the discharge ports are reinforced with wear-resistant tungsten carbide sleeves, significantly extending the service life of these high-wear components.

Compact and Service-Friendly Design

The GNLW364 adopts a compact layout, with both motors positioned at one end of the machine. This design not only saves space but also simplifies maintenance. GN’s decanters are also engineered for easy disassembly, and for larger models, hydraulic bearing removal systems are available to reduce the risk of component damage during maintenance.

Trusted by Global Environmental Companies

The overseas environmental firm selected the GNLW364 after rigorous evaluation due to its high dewatering performance, intelligent control system, and low maintenance requirements. With its reliable performance and energy-efficient operation, the GNLW364 is now playing a key role in helping the company meet strict environmental discharge standards and reduce waste handling costs.
