GN Separation has recently finished delivering and commissioning a vibrating screen system for a domestic iron ore mine, bolstering the customer’s continuous endeavors to enhance mineral processing efficiency and comply with the increasingly rigorous industry standards. The supplied equipment comprises one Large Linear Vibrating Screen (GNLSP3073) and four 5-Deck Stack Vibrating Screens (GND5Z1014), which together create an integrated screening solution tailored to various stages of the beneficiation process.
In recent times, the iron ore mining and processing sector has encountered numerous challenges, including dwindling ore grades, elevated product quality demands, and intensified pressure on energy consumption and environmental impact. Consequently, efficient screening and classification equipment have emerged as crucial elements in optimizing process flows, ensuring stable downstream separation, and minimizing overall operational costs. Considering the customer’s site-specific conditions and process objectives, GN provided a blend of high-capacity linear screening and high-efficiency fine screening equipment to satisfy both throughput and precision needs.
The GN Large Linear Vibrating Screen (GNLSP3073) primarily consists of a box-type vibration exciter, screen box, vibration damping springs, support structure, and driving device. Its linear vibration path guarantees steady material movement and effective separation across the entire screen surface. The screen can be installed horizontally or at an inclined angle, depending on process requirements. In this iron mine project, the large linear vibrating screen is mainly utilized for wet classification, dewatering, and related processes, assisting in the removal of excess water and oversized particles prior to downstream beneficiation. This type of equipment finds broad applications not only in mineral processing but also in coal preparation, gravel aggregate production, construction materials, and the chemical industry. GN also offers customization options for single-layer or double-layer screen surface structures and overall screen dimensions to meet specific customer needs.
GN also provided four GND5Z1014 5-Deck Stack Vibrating Screens to boost fine material classification efficiency. This stack vibrating screen, developed independently by GN, is particularly well-suited for wet screening, classification, and dewatering of fine-grained materials. It can be configured with 2 to 5 screen decks according to on-site requirements, enabling multiple particle size separations within a compact space. The GN Stack Vibrating Screen employs a unique vibration mode, driven by a single vibration source with dual vibration motors. By leveraging the principle of two-degree-of-freedom resonance, the entire machine achieves linear vibration, combining energy efficiency with superior screening performance.
Thanks to its advanced design, the GN Stack Vibrating Screen boasts high screening efficiency, substantial processing capacity, a simple structure, and stable, reliable operation. It is widely acknowledged as one of the leading solutions in the field of fine particle screening. The equipment is equipped with polyurethane screen mesh, which effectively reduces maintenance frequency and operational costs for the mine.
The successful implementation of GN vibrating screens in this domestic iron mine once again underscores GN’s technical prowess and practical experience in mineral processing equipment. GN will persist in focusing on technological innovation and customized solutions, providing dependable screening and separation equipment to support the sustainable development of the mining and processing industry.
