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.

GNLMZ2448 Linear Dewatering Vibrating Screen Successfully Shipped Out of the Factory to Serve Domestic Mining Development Soon


GN Separation, a global leader in solid-liquid separation, announced that its flagship mid-weight linear dewatering vibrating screen GNLMZ2448, which was developed independently, has passed the full process test and will be delivered to a large domestic mining site for production. With five core technology breakthroughs, this equipment redefines the market standard of mid-range mining vibrating screen, helping mining customers realize the goal of cost reduction and efficiency and sustainable development.
Linear dewatering screen: the core hub of modern ore dressing process
In the complex and changeable ore processing process, linear dewatering screen bears a double mission: it needs to efficiently separate solid-liquid mixtures and accurately complete the classification of particle size. Its core value is reflected in:
Enhancement of quality and efficiency: through the optimization of material distribution and dewatering path, concentrate recovery can be increased by 5-8%;
Cost control: reduce the load of downstream thickening and filtration, lowering overall operating costs;
Process adaptation: modular design can flexibly match the wet processing needs of different ore types (e.g. iron ore, copper ore, gold ore).
GNLMZ2448: Five Innovations Leading the Industry Upgrade
As the benchmark of GN Separation's middle-weight product line, the GNLMZ2448 integrates a number of patented technologies and is specially designed for severe working conditions:
Upgraded power heart
Equipped with double OLI industrial-grade vibration motors, the brand is known for “millions of hours of trouble-free operation” to ensure the stability of 7×24 hours continuous operation, and reduce energy consumption by 12% compared with traditional motors.
Weldless screen surface structure
Aircraft-grade Huck riveting process is used instead of traditional welding, eliminating the risk of metal fatigue caused by thermal stress, and extending the life of the screen body by more than 30%.
Intelligent modularized screen panels
The polyurethane screen panels are installed independently in sections, and can be replaced within 15 minutes for localized wear and tear, which improves the maintenance efficiency by 60%; the special rhombic hole design prevents clogging of the holes, and the permeability rate is increased by 22%.
Conveying and accelerating system
The feed end is equipped with 30°adjustable deflector, forming “waterfall” material distribution, increasing the dewatering efficiency by 40%, and the processing capacity is up to 800 tons/hour.
Full-dimensional protection system
Critical areas are coated with 3mm thick polyurea elastomer coating, which has been verified by ASTM G154-16 UV test, and the weather resistance is 8 times higher than that of ordinary epoxy coating, effectively resisting the corrosion of ore slurry.
Technology Empowerment for Green Mining
The launch of GNLMZ2448 responds to the global trend of ESG transformation in the mining industry:
Resource Recycling: Reduce the loss of fine-grained minerals and improve resource utilization through precise particle size control;
Low-carbon operation: High-efficiency motors and lightweight design reduce carbon emissions;
