2. Process Optimization: Enhancing concentrate quality through precise moisture control improves downstream metallurgical yields
3. Environmental Stewardship: Minimizing wastewater generation aligns with strict environmental regulations while reducing disposal liabilities

Innovative Features of the GNLMZ1836 Series

The GNLMZ1836 model incorporates cutting-edge engineering solutions that establish new benchmarks for durability and operational efficiency:

1. FEA-Engineered Screen Deck Architecture
   • Advanced finite element analysis ensures optimized structural integrity under extreme dynamic loads
   • Custom-designed frame geometry distributes stress patterns for enhanced longevity in abrasive environments
2. HUCK Fastening Technology
   • Patented HUCK rivets replace conventional welding, creating maintenance-free joints with superior shear strength
   • Eliminates stress concentrations and corrosion vulnerabilities inherent in welded assemblies
3. Polyurea Protective Systems
   • Dual-layer polyurea coating provides unmatched resistance to abrasion and chemical corrosion
   • Extends component service life by 30-50% compared to standard epoxy coatings
4. Modular Polyurethane Screening
   • Interchangeable polyurethane panels enable rapid screen media replacement (under 2 hours)
   • Available in multiple aperture configurations to accommodate varying ore characteristics

The system's proprietary vibration mechanism integrates frequency-controlled exciters with intelligent amplitude modulation, ensuring precise particle stratification and efficient slurry dewatering across feed rates from 50-500 t/h. This technological synergy positions GN Separation at the forefront of mineral processing innovation, delivering solutions engineered to maximize operational uptime and return on investment.

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;
Environmentally friendly: modular design supports rapid disassembly and recycling, reducing industrial waste.

GN Separation, a global leader in industrial separation, will be exhibiting at the 26th IE expo China, which will be held April 21-23, 2025 at the Shanghai New International Expo Center (SNIEC). As Asia's premier environmental technology event, the show will attract more than 2,500 exhibitors and 100,000 professional visitors, and GN Separation will bring its three core separation equipment - full hydraulic centrifuge, three-phase decanter centrifuge, and solids vacuum pump - to showcase its industry-leading technology and green solutions. Green solutions.

Fully hydraulic centrifuge: a new benchmark for high-efficiency solid-liquid separation
Breaking through the limitations of traditional mechanical drive, GN fully hydraulic centrifuge realizes compact design and low-maintenance operation through innovative hydraulic system. Its core advantage lies in the stepless speed control technology, which can precisely regulate the speed to suit complex materials with different solid contents (such as high-viscosity slurries or thin suspensions), ensuring separation efficiency while significantly reducing energy consumption. This technology is particularly suitable for the chemical, mining and environmental protection sectors, providing a flexible solution for industrial scenarios where multi-phase mixtures are handled.

Three-phase decanter centrifuge: three-phase separation in one machine
Equipped with patented centripetal pump technology, the three-phase decanter centrifuge separates light and heavy liquids and solids in a single continuous process by means of ultra-strong centrifugal force, completely overturning the multi-phase separation model. Its application scenarios cover:

Oil and gas industry: efficient separation of oil, water and rock chips in drilling fluid;
Biofuel industry: extraction of glycerol, methanol and separation of biomass residue;
Chemical manufacturing: purification of solvents and catalyst recovery.
This equipment helps companies realize cost reduction and efficiency by reducing the space occupied by the equipment and operating costs.
Solid vacuum pumps: all-round material handling innovators
Designed on the fully pneumatic conveying principle, the solids vacuum pump can flexibly handle a wide range of materials from low-solid slurries to high-solid suspensions, powders and even gravel. Its modular design supports rapid adaptation to different working conditions, significantly improving production efficiency. In the building materials, food and environmental protection sectors, the pumps are the preferred choice for material handling due to their stability and low maintenance costs.
