The GNLS3661 Large Linear Vibrating Screen is part of the heavy-duty screening equipment range designed and manufactured by GN Separation Equipment Co., Ltd, a global supplier specializing in solid-liquid separation and industrial screening technologies for mining, aggregates, coal processing, and mineral beneficiation industries.
This model is engineered for high throughput applications where consistent particle separation and operational stability are required. It is built on a linear motion vibration principle, driven by dual vibration exciters that generate a controlled linear trajectory across the screen surface. This motion ensures efficient material stratification and continuous conveying along the deck.
Technical overview
The GNLS3661 is designed with a relatively large screening area of approximately 21.96 m², making it suitable for medium-to-high capacity operations. Its main technical parameters include:
Vibration frequency: 14–16 Hz
Double amplitude: 7–10 mm
Motor power: 45 kW
Mesh size range: 0.2–25 mm
Processing capacity: 100–480 tons per hour
Vibration angle: 45°
Horizontal installation (0° inclination)
These parameters allow the machine to handle a wide range of materials, from fine particles to coarse aggregates, under both dry and wet conditions.
Industrial applications
The GNLS3661 is widely applied in:
Mining and mineral processing plants
Coal preparation and classification systems
Construction aggregate production
Chemical and bulk material industries
Typical operations include size classification, dewatering, desliming, and impurity removal, depending on the process configuration.
Engineering design and performance benefits
One of the key strengths of this equipment lies in its robust structural design. The screen box is engineered to minimize stress concentration and improve fatigue resistance, ensuring long-term stability under continuous operation.
The linear motion design enhances screening efficiency by improving material stratification and reducing blinding of the screen surface. This results in higher throughput and more consistent separation performance.
Maintenance is simplified through modular screen panels, which can be replaced individually without extensive downtime. Additionally, the vibration system is optimized for energy efficiency, reducing operational costs in long-term use.
System integration and process efficiency
In modern industrial plants, the GNLS3661 is often integrated into complete separation systems provided by GN Separation, alongside decanter centrifuges, dewatering equipment, and conveying systems. This allows operators to build fully integrated processing lines with improved automation and material handling efficiency.
Overall, the GNLS3661 Large Linear Vibrating Screen represents a reliable solution for industries requiring high-capacity, continuous screening performance with stable operation and low maintenance demands.
