Mining operations produce enormous volumes of tailings — a slurry composed of fine solids, water, and residual minerals — that must be properly treated before reuse or disposal. Traditional tailings ponds and dams are facing increasing challenges, from limited space to stricter environmental regulations. In this context, decanter centrifuges are transforming tailings management by enabling rapid, efficient solid-liquid separation with minimal environmental impact.
GNLW764: Engineered for Large-Scale Mining Applications
The GNLW764 Decanter Centrifuge, GN Separation’s largest and most powerful model, is specifically designed for large-scale operations such as mining tailings dewatering and TBM slurry treatment. Featuring a 30-inch (764 mm) bowl and heavy-duty construction, it delivers high throughput and reliable performance under demanding conditions. To withstand abrasive slurries, critical wear zones — including the screw conveyor blades and solids discharge ports — are protected with tungsten carbide coatings, ensuring exceptional durability, reduced maintenance, and long service life.

The centrifuge is also equipped with a Variable Frequency Drive (VFD) control cabinet, allowing precise adjustment of rotational speed to suit different materials. Real-time monitoring of vibration and temperature enhances operational safety and ensures stable, efficient performance.
Optimized Dewatering with the GNSJY6000 Flocculation Unit
For even better separation results, GN recommends integrating the GNLW764 with its GNSJY6000 Flocculation Dosing Unit. This automated system accurately injects flocculants into the slurry, causing fine particles to bind into larger clusters that separate more easily. The combined setup boosts solids recovery, increases water clarity, and reduces overall processing costs.
In summary, the GNLW764 Decanter Centrifuge represents a powerful, sustainable solution for modern mining operations. By combining advanced materials, intelligent control, and complementary flocculation technology, it helps operators achieve efficient, eco-friendly, and cost-effective tailings management.
With the GNLW764 Decanter Centrifuges now ready for dispatch, GN Separation is poised to strengthen its position as a professional solution provider in industrial separation technologies, delivering value to clients and contributing to a more sustainable future for the mining industry.
