GN Separation has recently completed the delivery of over 10 sets of vibrating screening units for a domestic ilmenite mining operation. The order includes GN Stack Vibrating Screens as well as large-scale Banana Vibrating Screens, reinforcing GN's proven manufacturing strength and technical expertise in fine mineral processing and screening technology.

GN Stack Vibrating Screen — Precision Wet Screening & Dewatering

The GN Stack Vibrating Screen is engineered for wet screening, classification, and dewatering of fine-grained materials across mineral processing, coal preparation, and related industries. Depending on site-specific needs, the machine can be configured with 2 to 5 screen decks, delivering highly adaptable solutions for diverse operating conditions.

As a wholly self-developed GN product, the Stack Screen operates on a two-degree-of-freedom resonance principle. A single vibration source equipped with dual vibration motors drives the entire machine in a linear motion pattern.

Compared with traditional screening equipment, the GN Stack Vibrating Screen stands out for its distinctive vibration mode, superior screening efficiency, energy-saving performance, and high throughput capacity. Built with advanced engineering, the machine features a streamlined structure and dependable operation — positioning it among the most sophisticated fine-material screening solutions available today. Additionally, the screen is fitted with premium polyurethane screen panels that deliver outstanding wear resistance, extended service life, and reduced maintenance expenses.

GN Banana Vibrating Screen — High-Efficiency Coarse & Medium Particle Screening

For the coarse and medium particle screening stages of the project, GN supplied large Banana Vibrating Screens. Each unit comprises a box-type vibration exciter, screen box, vibration-damping springs, support frame, and driving system. The linear vibration trajectory ensures smooth material transport and consistently high screening performance.

The Banana Screen features a multi-stage broken-line screen surface with progressively changing angles. The steeper inclination at the feed end accelerates material movement and enables rapid stratification — ideal for screening easily separable particles. As the angle gradually decreases toward the discharge end, the material flow slows, increasing the probability of successful screening and markedly boosting overall efficiency.

Proven Capability, Global Reach

Backed by reliable product quality and deep expertise in mining and mineral separation, GN continues to deliver professional screening and separation solutions to customers worldwide. The successful commissioning of more than 10 sets of GN vibrating screens at this domestic ilmenite mine further validates GN's ability to manage large-scale mineral processing projects and provide equipment solutions that are efficient, stable, and cost-effective.

GN Separation is pleased to announce the successful delivery of a fully integrated, containerized oily sludge treatment system to a client based in Africa. This turnkey solution delivers efficient, safe, and environmentally responsible treatment of oily sludge, addressing the complex demands of industrial and oilfield operations across the region.

A Fully Integrated, Multi-Module System

The GN containerized system combines several purpose-built modules—including a pre-mixing tank, vibrating screen, three-phase decanter centrifuge, and chemical dosing unit—into one compact, mobile platform. Each module is precisely engineered to manage a specific stage of the treatment process, ensuring seamless and high-performance operation from start to finish.

The system employs a chemical-assisted mechanical separation process to fully treat oily sludge. Sludge is first heated and conditioned in the pre-mixing tank, then coarse solids are removed through the vibrating screen. The conditioned material is subsequently fed into the three-phase decanter centrifuge, where dewatering and precise oil-water-solid separation take place. Strategic chemical dosing further boosts oil recovery rates, ensuring that all treated output meets stringent discharge and environmental compliance standards.

Built for Diverse Sludge Types

GN's containerized solution is well-suited for a wide range of oily sludge, including refinery sludge, drilling waste, oil tank cleaning residues, and other industrial byproducts. By integrating chemical hot washing with advanced mechanical separation, the system achieves maximum oil recovery while significantly reducing waste volume—delivering a dependable and cost-effective answer for clients around the globe.

As a leading manufacturer of turnkey oily sludge treatment systems, GN specializes in customized solutions designed around the unique properties of each client's sludge. Our expert team performs in-depth analysis of sludge composition and operational needs, empowering clients to reach peak treatment performance and operational efficiency.

Compact, Mobile, and Ready for Deployment

Engineered for easy transport, fast setup, and a minimal on-site footprint, GN's containerized system is an ideal fit for remote or logistically challenging project sites. This latest delivery to our African partner reflects GN's ongoing dedication to innovation, sustainability, and excellence in oily sludge management.

With GN's containerized oily sludge treatment system, clients gain access to dependable oil recovery, environmentally compliant disposal, and streamlined operations—all from a single, fully integrated solution.
