GN Separation has developed its high-frequency stack vibrating screen technology to provide efficient fine particle screening and classification solutions for the mining industry. Recently, GN introduced its Stack Vibrating Screen to a domestic mining company, offering a solution designed to improve screening efficiency, optimise processing capacity and reduce equipment footprint.

High-Efficiency Fine Particle Screening

In mineral processing operations, efficient fine particle screening is essential for improving product quality and optimising downstream processes. Conventional screening equipment can face challenges when handling fine materials, particularly in wet screening applications where screen blinding and limited screening capacity may affect operational efficiency.

GN High Frequency Stack Vibrating Screen is specifically designed for wet screening, particle classification and dewatering applications involving fine-grained materials.

Featuring a multi-layer screen deck configuration, the equipment can be customised with 2 to 5 screening layers according to the customer's processing requirements. This design allows multiple screening operations to be performed within a compact footprint, increasing the effective screening area per unit of installation space.

Advanced Vibration Technology

GN Stack Vibrating Screen adopts a dual-motor self-synchronisation design based on the two-degree-of-freedom resonance principle. Driven by two vibration motors, the screen box generates linear vibration to achieve efficient material separation.

Operating at a vibration frequency of 25 Hz, the equipment is designed to deliver high screening efficiency while maintaining relatively low energy consumption and stable operation.

Key technical advantages include:

• Multi-layer screening design: Available in 2 to 5 screening layers to accommodate different classification requirements.

• High screening efficiency: Designed for fine particle separation, with mesh apertures ranging from 0.045 mm to 2 mm.

• Compact footprint: Multiple screening decks increase screening capacity per unit of installation area.

• Energy-efficient operation: Resonance-based vibration technology helps reduce power consumption.

• Reliable operation: Dual imported vibration motors provide stable vibration performance.

Polyurethane Screen Mesh for Extended Service Life

The GN Stack Vibrating Screen is equipped with polyurethane screen mesh, offering good elasticity, wear resistance and resistance to screen blinding.

The polyurethane screen mesh features an opening ratio of approximately 28%–45%, helping maintain effective screening performance while handling fine materials.

Under suitable operating conditions, the average service life of the screen mesh can exceed six months, helping reduce replacement frequency and routine maintenance requirements.

The screen deck also accommodates multiple screen panels within each layer, providing flexibility for different screening configurations.

Designed for Mining Applications

GN Stack Vibrating Screen is suitable for a range of mineral processing and coal preparation applications, particularly where fine particle wet screening, classification and dewatering are required.

Its modular multi-layer configuration allows the equipment to be selected according to material characteristics, required separation size, processing capacity and available installation space.

For mining operations looking to improve fine particle screening efficiency, GN provides customised equipment configurations to meet individual project requirements.
