In various industries such as mining, coal, building materials, metallurgy, and chemical engineering, the GN Dewatering Vibrating Screen finds extensive application. The linear motion dewatering vibrating screen is particularly suitable for dewatering, desliming, de-mucking, and dry discharge of tailings in mines. This equipment is designed with advanced techniques such as finite element analysis and fatigue analysis to ensure rational screen structure, low energy consumption, and high dewatering and dry discharge capacity. It can adapt to various corrosive and abrasive working conditions, offering high throughput, efficiency, and stable performance. Moreover, the machine dimensions can be customized according to customer requirements.The GN Dewatering Vibrating Screen is equipped with two vibration motors mounted on the top, utilizing the principle of reverse self-synchronization to induce linear motion in the screen body. The synchronous vibration of the screen body drives the material on the screen surface, causing the material to impact and bounce on the screen surface, thus achieving solid-liquid separation and coarse-fine particle separation. Material is continuously fed directly from the feed tank or cyclone separator onto the screen surface for dewatering and desliming. The materials on the upper and lower sides of the screen are respectively discharged into upper and lower receiving tanks and proceed to the next process. The angle between the direction of vibration force and the horizontal direction can be designed according to the characteristics of the materials on-site, determining the running speed of materials on the screen surface and the processing capacity of the equipment.

Recently, GN Separation has successfully completed the manufacturing and assembly of a batch of linear motion dewatering vibrating screens for iron ore, and successfully conducted factory trials. This innovative product is soon to be delivered to domestic customers, injecting new vitality into the iron ore screening process.

In the field of iron ore processing, dewatering screening is a crucial step in enhancing processing efficiency and quality. The linear motion dewatering vibrating screen from GN is specifically designed to meet this demand. Its outstanding features include the use of Huck rivets to connect the screen box wall panels, effectively avoiding stress issues associated with traditional welding. Additionally, it employs well-known OLI brand vibrating motors to ensure efficient and stable operation. The polyurethane screen deck, renowned for its excellent wear resistance and corrosion resistance, provides solid support for the equipment’s lifespan and screening efficiency.

Moreover, the modular installation design simplifies and speeds up screen panel replacement, significantly reducing downtime. The large screening area enables more efficient dewatering, rapidly boosting iron ore processing efficiency. The adjustable installation angle of the equipment adapts to different working environments and conditions, fully demonstrating GN’s technical prowess and innovative spirit.

The working principle of the GN linear dewatering vibrating screen is equally impressive. By installing two vibrating motors and utilizing the principle of reverse self-synchronization, the screen body is set into linear motion, transmitting force to the material on the screen. This impact causes the material to be thrown up on the screen surface, achieving solid-liquid separation and the separation of coarse and fine particles. Material is continuously fed through a feed chute or hydrocyclone, undergoing dewatering and desliming processes on the screen surface. The oversize and undersize materials are then discharged into separate collection bins, ready for the next processing stage. The angle between the excitation force direction and the horizontal can be designed based on the material properties at the customer site, as this angle determines the material’s movement speed on the screen surface and the equipment’s processing capacity.

In addition to linear dewatering vibrating screens, GN Separation offers a range of other mining vibrating screens, such as high-frequency fine screens, banana screens, and flip-flop screens. These equipment are widely used in screening operations for mineral resources such as iron ore, coal, and non-ferrous metals, providing customers with comprehensive and efficient screening solutions.

GN Separation has always been customer-oriented, committed to developing and producing efficient and stable mining screening equipment. In the future, GN will continue to delve deeper into the mining equipment sector, contributing more innovative forces to global mining development. Let’s look forward to GN’s continued excellent performance in the mining industry!
