GN Separation has successfully completed the assembly and factory testing of four GNLW764 Big Bowl Decanter Centrifuges for a client in Peru. These high-capacity machines, purpose-built for demanding industrial environments, will play a key role in tailings dewatering within the mining sector—helping operators improve water recovery, environmental compliance, and overall operational efficiency.
Mining operations generate enormous volumes of tailings—a slurry of water, fine solids, and residual minerals—that must be effectively treated before disposal or reuse. Traditional tailings management methods, such as ponds or dams, are increasingly challenged by limited space, environmental concerns, and stricter regulations.
Decanter centrifuges have emerged as a modern and sustainable alternative, enabling rapid and efficient solid-liquid separation. By mechanically separating solids from the liquid phase, these systems significantly reduce the need for large settling ponds and facilitate water recycling back into the process.
GNLW764: Engineered for Large-Scale Industrial Applications
The GNLW764 Decanter Centrifuge—GN Separation’s largest and most powerful model to date—is specifically engineered for high-throughput applications. With a bowl diameter of 30 inches (764 mm) and a robust construction, it is ideally suited for mining tailings dewatering, tunnel boring machine (TBM) slurry treatment, and other industrial processes requiring substantial processing capacity.
1. Tungsten Carbide Protection for Maximum Durability
Mining environments are highly abrasive, with tailings containing coarse particles that can quickly erode standard components. To address this, GN Separation equips the GNLW764 with tungsten carbide coatings on critical wear parts, including the screw conveyor blades and solids discharge ports.
Tungsten carbide’s exceptional hardness and resistance to wear and corrosion extend service life, reduce maintenance frequency, and ensure stable, long-term operation—even under the harshest conditions.
2. VFD Control Cabinet for Precision and Safety
Each GNLW764 centrifuge comes with a Variable Frequency Drive (VFD) control cabinet, allowing precise adjustment of bowl and conveyor speeds to match different feed conditions. This flexibility enables operators to fine-tune performance for materials ranging from fine clays to coarser minerals.
The VFD system also incorporates real-time monitoring of temperature, vibration, and other operating parameters, ensuring safe and reliable performance throughout operation.
Complementary Technology: GNSJY6000 Flocculation Dosing Unit
To maximize dewatering performance, GN Separation recommends pairing the GNLW764 with its GNSJY6000 Flocculation Dosing Unit. This automated system injects flocculants—chemicals that bind fine particles into larger aggregates—into the feed slurry. Optimized flocculation significantly enhances solids capture efficiency and water recovery, ensuring superior overall performance.
As the global mining industry continues to focus on sustainability, water management, and operational efficiency, GN Separation remains committed to supporting its clients through advanced technology, dedicated R&D, and a responsive global service network.
With the successful completion and shipment of these four GNLW764 centrifuges, GN Separation further strengthens its position as a leading provider of industrial separation solutions, contributing to a cleaner and more sustainable future for the mining industry.
