As mineral processing projects continue to demand higher efficiency and finer classification, GN Separation is proud to announce the delivery of 13 units of 5-deck stack vibrating screens for a large-scale ilmenite ore classification project. This milestone highlights GN’s commitment to providing reliable, high-performance screening solutions for the miningindustry.
Importance of Accurate Ilmenite Classification
Ilmenite is a major titanium-bearing mineral used widely in the production of titanium dioxide, a key material for paints, coatings, plastics, and aerospace applications. Effective classification during ore preparation is essential to ensure high recovery rates and stable product quality. GN’s multi-deck screening technology is designed to meet these demands by offering high-capacity, fine particle separation in a compact configuration.
Key Features of GN’s 5-Deck Stack Vibrating Screen
GN’s stack vibrating screen—also known as a stack sizer—is specifically developed for wet screening and fine classification of mineral ores. Each of the 13 units supplied for this project incorporates the following features:
1. High-Efficiency Multi-Deck Design
Each screen consists of five individual screening decks, allowing simultaneous separation of multiple size fractions while maintaining a small footprint.
2. High-Frequency Linear Vibration
Driven by two synchronized vibration motors, the screen operates through a two-degree-of-freedom resonance system. This design achieves high vibration strength, reduces screen blinding, and improves separation efficiency for fine and challenging materials.
3. Durable Polyurethane Screen Mesh
Each deck is equipped with high-strength polyurethane (PU) mesh panels known for their flexibility, anti-blocking performance, and long service life.
4. Modular Construction for Easy Maintenance
The feeding distribution box and screen frames are modular and easy to assemble or replace, enabling maintenance on individual decks without disassembling the entire unit.
5. Enhanced Wear and Corrosion Resistance
The screen surfaces are coated with a protective layer, and all structural components are treated to withstand abrasive and corrosive mining environments.
Benefits for Ilmenite Processing
For ilmenite classification, GN’s 5-deck stack vibrating screen provides several key advantages:
-
Stable and accurate particle size separation
-
Efficient handling of high-throughput slurry
-
Reduced processing footprint due to vertical stacking
-
Lower operating and maintenance costs through a durable, service-friendly design
-
Improved downstream performance for magnetic separation or flotation
By using multi-deck high-frequency screening, mineral processors can achieve higher recovery rates and better product consistency—critical factors in titanium ore beneficiation.
