Decanter Centrifuge & Vibrating Screen Manufacturer

GN Separation is pleased to announce the shipment of 13 units of 5-deck stack vibrating screens for a mineral processing project focused on ilmenite ore grinding and classification. The equipment, shown in the project images titled “Frequency Stack Screen” and “Stack Vibrating Screen for Ilmenite”, will be installed in the customer’s fine classification circuit to support stable particle size control and enhance overall process performance.

 

This batch of equipment is designed for fine classification of ilmenite slurry within a closed-circuit grinding system. Each unit adopts a compact 5-deck structure, allowing multiple layers of screening within a single machine frame. This configuration offers a high screening surface area relative to the overall footprint, making it well suited for facilities where installation space is planned carefully. Compared with conventional screening approaches, the multi-deck arrangement provides improved utilization of equipment layout and helps the plant achieve a more organized process flow.

During the design and manufacturing process, GN prioritized stability, screening accuracy, and adaptability to various feed conditions. The high-frequency vibration system is engineered to support consistent stratification of fine particles, helping maintain a stable cut size and supporting uniform classification results. To accommodate the characteristics of ilmenite ore, the structure is built with abrasion-resistant materials, and key components are configured for durability in continuous operation.

In grinding circuits, precise classification plays an important role in overall process performance. The 5-deck stack vibrating screen is applied to separate fine particles suitable for downstream concentration from coarser material that requires further grinding. A stable classification process can support improved grinding efficiency, better management of circulating load, and a more predictable feed size distribution. These factors collectively contribute to a smoother production flow in ilmenite beneficiation.

To support long-term operation, GN has incorporated a modular screen panel design, enabling convenient replacement and maintenance. The vibration system and distribution manifold are arranged in a way that aims to reduce downtime during routine service operations.

Each of the 13 units has undergone factory testing prior to shipment, including vibration performance checks, structural inspections, and assembly verification. GN’s quality control procedures follow internal standards developed for mineral separation equipment, ensuring that every delivered machine aligns with the project’s technical requirements.

The deployment of these stack vibrating screens reflects GN Separation’s continued commitment to providing equipment solutions for mineral classification and fine particle processing. With experience in screening, solid-liquid separation, and mineral concentration support systems, GN aims to deliver equipment that meets operational expectations across different project scales.

GN Separation will continue to support the client throughout installation, commissioning, and operational phases. The company remains focused on upgrading its product line, developing technologies for fine classification, and serving mineral processing industries such as ilmenite, zircon, silica sand, and other industrial minerals.
