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.
