GN Separation is excited to announce the dispatch of 13 five-deck stack vibrating screens for a mineral processing project centered on the grinding and classification of ilmenite ore. As illustrated in the project images labeled “Frequency Stack Screen” and “Stack Vibrating Screen for Ilmenite,” this equipment will be installed in the customer's fine classification circuit. Its purpose is to ensure stable particle size control and enhance the overall performance of the process.

Equipment Design and Functionality

This shipment of equipment is specifically tailored for the fine classification of ilmenite slurry within a closed-circuit grinding system. Each unit features a compact five-deck structure, enabling multiple layers of screening within a single machine frame. This design offers a large screening surface area relative to its overall footprint, making it an ideal choice for facilities where installation space is limited and carefully planned. Compared to traditional screening methods, the multi-deck setup optimizes equipment layout utilization and contributes to a more organized process flow within the plant.

During the design and manufacturing stages, GN placed a high priority on stability, screening accuracy, and adaptability to various feed conditions. The high-frequency vibration system is engineered to ensure consistent stratification of fine particles, maintaining a stable cut size and delivering uniform classification results. To withstand the unique characteristics of ilmenite ore, the structure is constructed using abrasion-resistant materials, and key components are designed for durability during continuous operation.

Importance in Grinding Circuits

In grinding circuits, precise classification is crucial for overall process performance. The five-deck stack vibrating screen is used to separate fine particles, which are suitable for downstream concentration processes, from coarser material that requires further grinding. A stable classification process enhances grinding efficiency, improves the management of the circulating load, and ensures a more predictable feed size distribution. These factors collectively contribute to a smoother production flow in ilmenite beneficiation.

Maintenance and Longevity

To facilitate long-term operation, GN has incorporated a modular screen panel design. This allows for easy replacement and maintenance of screen panels. Additionally, the vibration system and distribution manifold are arranged to minimize downtime during routine service operations, ensuring that the equipment remains operational with minimal interruptions.

Quality Assurance

Before shipment, each of the 13 units underwent comprehensive factory testing. This included checks on vibration performance, structural inspections, and assembly verification. GN's quality control procedures adhere to internal standards developed specifically for mineral separation equipment, ensuring that every machine delivered meets the project's technical requirements.
