GN Large Linear Vibrating Screen is widely using in fields of metallurgical mines, coal, non-ferrous metals, construction materials, chemical industry and others.

GN Large Banana Vibrating Screen is largely using in raw coal classification, desliming and coal demineralization, crushing and classification of metal mines, sand and gravel aggregate and other industries.

1. Large Linear Vibrating Screen

Large linear vibrating screen is a linear motion screen composed by Box Type Vibration Exciter, Screen Box, Vibration Damp Spring, Support and Driving Device. The screen deck can be working horizontally or at an inclined angle, and screen deck can be build by single layer or double layers to meet various harsh working conditions.

In wet classification, demineralization, dewatering, tailings dry discharge and other processes related with mineral processing, coal preparation, gravel aggregate, construction materials, chemical industry and other industries, GN large linear vibrating screen always plays a vital important role.

2. Large Banana Vibrating Screen

Banana vibrating screen is also known as equal thickness screen, it adopts the principle of equal thickness screening and the screen surface adopts the design method of different inclination angles’ multiple screens like the modeling of banana. With its large processing capacity, high screening efficiency and stable performance, it has won the favor of the majority of users. GN Large Banana Vibrating Screen is suitable both for dry classification and wet dehydration, and screening of ore or coal and other materials no matter it is large or medium-sized coal mines, power plants, chemicals, steel and other industries.

GN large banana vibrating screen has pretty similar composition with GN large linear vibrating screen. The combination of continuous multi-stage angles screen surface design has the advantage of large feeding end, which can move the materials rapidly in different layers, and screening materials effectively. With the decrease of the inclination of the screen surface near the discharge end, the flow rate of the material decreases accordingly, which increases the screening probability and efficiency. GN large banana vibrating screen is mainly used in dry and wet classification, desliming, demineralization and other related processes.

• Low impact toughness due to the high-strength alloy steel plate screen wallboard is without welding. Free of welding residual stress by using imported Huck rivets for hydraulic tension assembly.
• Excellent structure and vibration parameters by the apply of finite element analysis to reduce the influence of resonance, and extend the service life.
• Rectangular tube to compose the cross beam; Light weight, high strength and good toughness of the exciting beam box structure. The post welding heat treatment process of main components without welding stress.
• Beam surface is sprayed with Polyurea by one US made Spray Machine. Wearable parts are protected by rubber parts, which are resistant to erosion and wear.
• High efficiency helical gear box type exciter, with super large exciting force, stable operation, ultra-low noise and long service life; Outer design of eccentric block, the amplitude can be adjusted easily by changing the counterweight setting.
• Customized design to meet different customers’ demand; Modular Polyurethane screen panel, more versatile and more convenient to replace.
