We are excited to announce that four units of the GNLS3061 Large Linear Vibrating Screen are ready for shipment to a domestic iron mine! This significant milestone underscores our commitment to delivering high-quality, efficient equipment tailored to meet the diverse needs of our customers in the mining and mineral processing industries.

Overview of GNLS3061 Large Linear Vibrating Screen

The GNLS3061 is a robust and versatile large linear vibrating screen designed to handle various bulk material processing tasks. Here’s a closer look at what makes this model a standout choice for mining and industrial applications:

1. High Screening Efficiency and Versatility

The GNLS3061 offers a substantial screen area of 18.3 m², making it suitable for high-capacity applications. This model is part of our large linear vibrating screen series, which includes other models such as GNLS2461, GNLS3661, GNLS3673, GNLS4361, and GNLS4373, catering to a range of capacities and screen area requirements.

2. Advanced Design Features

The GNLS3061 features advanced design elements that enhance its performance and longevity:

• Durable Construction: The screen machine is constructed from high-strength alloy steel plate with superior impact toughness. Instead of welding, the plate is assembled using imported Huck rivets, which eliminates welding residual stress and improves the screen’s durability.
• Optimized Structure: Finite element analysis has been used to optimize the structure and vibration parameters of the screen, reducing resonance and extending the service life of the machine.
• Efficient Vibration System: The screen is equipped with a high-efficiency helical gear box type exciter. This exciter generates a large exciting force with minimal noise, ensuring stable operation and a long service life. The amplitude can be adjusted by changing the counterweight setting on the eccentric block.
• Robust Beam Design: The cross beam under the screen uses a rectangular tube design for high strength and good toughness. Additionally, the surface of the beam is sprayed with polyurea for wear resistance, and rubber parts protect against erosion and wear in high-impact areas.
• Modular Screen Panels: The polyurethane screen panels are modular, making them versatile and easy to replace.

3. Working Principle

The GNLS3061 operates based on the principle of forced synchronization. Two gear box vibrators create a linear back-and-forth motion, which drives the screen surface to vibrate. This vibration causes the materials on the screen to move, allowing for effective screening, grading, and separation.

Materials are fed into the screen through a feeding trough, where they are subjected to the vibrating screen’s action. The materials are classified based on particle size, with the finer particles passing through the screen and the larger particles being conveyed to the next process.

The angle between the vibration direction and the horizontal plane can be adjusted based on the material properties and site requirements, which influences the processing capacity and efficiency of the equipment.

4. Technical Specifications

Here are some key technical specifications for the GNLS3061 model:

• Screen Area: 18.3 m²
• Vibration Direction Angle: 45°
• Vibration Frequency: 14–16 Hz
• Power: 30 kW
• Double Amplitude: 7–10 mm
• Mesh Size: 0.2–25 mm
• Capacity: 80–300 t/h

At GN SEPARATION, we take pride in our new solutions for industrial waste management. One of our flagship products, the GN Solids Vacuum Pump, also known as the sludge vacuum pump, is an innovation in the field of solids transfer. This vacuum loading solids transfer pump is fully powered by compressed air, making it an efficient and reliable solution for transferring solids, powder, slurry, and sludge.

What Makes GN Solids Vacuum Pump Stand Out?

The GN Solids Vacuum Pump is designed to be compact, robust, and incredibly efficient. It utilizes a powerful vacuum of 25″ hg to load materials and is capable of delivering them over distances of up to 500 meters. Available in three different capacities (10 m3/h, 20 m3/h, and 40 m3/h), these pumps can also be customized as Group Pump Units on a single skid, offering versatile and scalable solutions for various industrial needs.

Key Applications

The versatility of the GN Solids Vacuum Pump makes it suitable for a wide range of applications, including:

• Thickener De-sludge: Efficiently removes sludge from thickeners.
• Tunneling & TBM Applications: Ideal for tunnel boring machines and excavation projects.
• Sump and Shaft Cleaning: Cleans sumps and shafts effectively.

Working Principle of the GN Solids Vacuum Pump

The GN Solids Vacuum Pump operates on a simple yet powerful principle. Compressed air is fed into the pump, creating a high vacuum inside the pump tank. This vacuum draws materials into the tank through the suction line. After a few seconds, the valve changes the air direction to create positive pressure, pushing the material out of the pump tank through the discharge line.

The GNSP-40A, a larger model, offers both manual and automatic modes, while the smaller models, GNSP-10A and GNSP-20A, operate automatically. This pneumatic operation ensures safety and reliability, especially in hazardous environments like the oil, gas, and coal industries, where explosion-proof equipment is essential.
