GN Separation recently completed the delivery and commissioning of a vibrating screen system for a domestic iron mine, supporting the customer’s ongoing efforts to enhance mineral processing efficiency and comply with increasingly stringent industry requirements. The supplied system includes one large linear vibrating screen (GNLSP3073) and four units of 5-Deck Stack Vibrating Screens (GND5Z1014), forming an integrated screening solution covering multiple stages of the beneficiation process.

In recent years, the iron ore mining and processing industry has faced growing challenges, including declining ore grades, higher product quality expectations, and increasing pressure to reduce energy consumption and environmental impact. Under these conditions, efficient screening and classification equipment has become a critical factor in optimizing process flows, stabilizing downstream separation performance, and lowering overall operating costs. Based on the customer’s site conditions and process objectives, GN provided a tailored combination of high-capacity coarse screening and high-efficiency fine screening equipment to meet both throughput and accuracy requirements.

The GN large linear vibrating screen GNLSP3073 consists mainly of a box-type vibration exciter, screen box, vibration isolation springs, support structure, and drive system. Its linear vibration trajectory ensures uniform material distribution and stable movement across the entire screen surface, enabling effective separation. The screen can be installed horizontally or at an inclined angle to suit specific process needs. In this iron mine project, the large linear vibrating screen is primarily used for wet classification, dewatering, and related process stages, effectively removing excess water and oversized particles prior to downstream beneficiation. This type of equipment is widely applied not only in mineral processing, but also in coal preparation, sand and aggregate production, building materials, and chemical industries. GN can customize single-deck or double-deck screen configurations, as well as overall dimensions, to meet specific customer requirements.

To further enhance fine material classification efficiency, GN Separation supplied four units of the GND5Z1014 5-Deck Stack Vibrating Screens. This stack vibrating screen is a self-developed GN product, specifically designed for wet screening, fine classification, and dewatering of fine-grained materials. Depending on on-site process demands, the equipment can be configured with 2 to 5 screen decks, enabling multiple particle size separations within a compact footprint. The GN Stack Vibrating Screen adopts a unique vibration mode driven by a single excitation source with dual vibration motors. By applying the principle of two-degree-of-freedom resonance, the machine achieves linear vibration while maintaining high energy efficiency and excellent screening performance.

With its advanced design, the GN Stack Vibrating Screen offers high screening efficiency, large processing capacity, a simple structure, and stable, reliable operation. It is widely recognized as an advanced solution for fine particle screening. The equipment is fitted with polyurethane screen panels, which significantly extend service life while reducing maintenance frequency and overall operating costs for the mine.

This successful application of GN vibrating screen equipment at a domestic iron mine once again demonstrates GN Separation’s strong technical capabilities and extensive practical experience in mineral processing solutions. GN will continue to focus on technological innovation and customized system design, providing reliable screening and separation equipment to support the sustainable development of the global mining and mineral processing industry.
