GN Separation Equipment Manufacturer

GN Separation recently completed the fabrication of three units GNLW764 decanter centrifuges to a European sugar processing facility. The high-capacity machines, designed for dewatering applications, will play a critical role in treating wastewater generated during sugar beet washing operations.

Application of Decanter Centrifuges in Sugar Beet Processing

Sugar beet washing is a water-intensive process that generates large volumes of sludge-laden wastewater. If left untreated, this wastewater can pose environmental risks and increase operational costs for sugar producers. Decanter centrifuges, such as GN Separation’s GNLW764, are engineered to separate solids from liquids efficiently, reducing wastewater volume and enabling the recovery of reusable water. By treating beet washing effluent, these centrifuges help sugar processors comply with environmental regulations, lower water consumption, and improve operational sustainability.

Advanced Features of GN Separation’s GNLW764 Decanter Centrifuges

The GNLW764 is GN Separation’s largest independently designed dewatering decanter centrifuge, tailored for high-volume sludge dewatering in industries such as agriculture, mining, and tunneling. Key features that set it apart include:

1. Duplex Stainless Steel Bowl with Centrifugal Casting Technology
The centrifuge’s bowl, or "drum," is crafted from duplex stainless steel and manufactured using centrifugal casting. This process ensures uniform material density, eliminating internal defects and enhancing dynamic balance at high rotational speeds. The result is a durable, vibration-free operation that extends equipment lifespan and reduces maintenance needs.

2. Tungsten Carbide-Protected Screw and Discharge Port
To withstand abrasive wear from solids, the screw’s flights are reinforced with tungsten carbide wear plates, while the discharge port is protected by a tungsten carbide sleeve. These materials, known for their extreme hardness and corrosion resistance, minimize downtime caused by component degradation and lower long-term operating costs.

3. Automated Oil Lubrication System for Main Bearings
The GNLW764 features a real-time oil lubrication station for its main bearings, ensuring consistent lubrication under varying loads. This automation simplifies maintenance, reduces human error, and enhances reliability—critical factors for continuous operations in demanding industrial environments.

Applications beyond Sugar Beet Processing

While the GNLW764 excels in sugar beet wastewater treatment, its robust design and high throughput capacity make it ideal for other industries requiring large-scale sludge dewatering, including mining tailings dewatering, sewage sludge dewatering and tunneling mud recycling.
