Large Banana Vibrating Screen

GN large banana vibrating screen is mainly composed of box type vibration exciter, screen box, vibration damping spring, support and driving device, and the running amplitude track is linear. The broken line screen surface design formed by the combination of continuous multi-stage angles is adopted, and the inclination angle of the screen surface at the feeding end is large, which can make the materials move and layer rapidly, which is conducive to the screening of easy screening materials.

The broken line screen surface design formed by the combination of continuous multi-stage angles is adopted, and the inclination angle of the screen surface at the feeding end is large, which can make the materials move and layer rapidly, which is conducive to the screening of easy screening materials. With the decrease of the inclination of the screen surface near the discharge end, the flow rate of the material decreases, which increases the screening probability of the material and improves the screening efficiency. GN large banana vibrating screen is mainly used in dry and wet classification, desliming, demineralization and other process links.

    Large Banana Vibrating Screen Features

    • The screen machine wallboard is not welded, and the plate is made of high-strength alloy steel plate with better impact toughness. The imported Huck rivets are used for hydraulic tension assembly. This advanced design makes the wallboard free of welding residual stress.
    • Through finite element analysis, optimize the structure and vibration parameters of the screen, avoid the natural frequencies of all levels of the screen, reduce the influence of resonance, and extend the service life of the whole machine.
    • The cross beam under the screen adopts rectangular tube design; The exciting beam box structure is designed with light weight, high strength and good toughness. The post welding heat treatment process of main components can effectively eliminate welding stress.
    • The surface of the beam is sprayed with polyurea by a spray machine imported from the United States. The parts that are easy to impact and wear can also be protected by rubber parts, which are resistant to erosion and wear.
    • High efficiency helical gear box type exciter, with super large exciting force, ultra-low noise, stable operation and long service life; The eccentric block is arranged outside the exciter box, so that the amplitude can be adjusted by changing the counterweight setting.
    • Product serialization to meet the production requirements of customers under different process conditions; Polyurethane screen panel is modular, more versatile and more convenient to replace.

    Large Banana Vibrating Screen Working Principles:

    1. GN large banana vibrating screen is equipped with two gear box vibrators, which make the screen body move back and forth in a linear motion by using the principle of forced synchronization.
    2. Under the action of exciting force, the screen machine drives the screen surface to vibrate synchronously, and transmits the force to the materials on the screen, so as to impact the materials to be thrown up on the screen surface for layering and screening and grading according to the specified particle size.
    3. The broken line screen surface design formed by the combination of continuous multi-stage angles is adopted, and the inclination angle of the screen surface at the feeding end is large, which can make the materials move and layer rapidly, which is conducive to the screening of easy screening materials. As the inclination angle of the screen surface near the discharge end decreases, the flow rate of the material decreases, which increases the screening probability of the material and improves the screening efficiency and processing capacity.
    4. The included angle between the direction of the exciting force and the level can be designed according to the properties of the materials on the customer's site. This included angle determines the running speed of the materials on the screen surface and the processing capacity of the equipment.
