Vibrating Screen Machinery

Vibrating Screen Description
Vibrating screen works on circular motion. Long Yang brand 2YA rounding vibrating screen provides multi-layer round motive vibration. This type of material screen is equipped with long screening line and various screening specifications. Depending on barrel exciter and eccentric adjustment applied to its structure, the screen is featured with reliable structure, strong exciting force, high screening efficiency and low vibration noise. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line. There are many specifications for vibrating screen. It is widely used as screening materials in mining, building, transportation, energy, chemical industry, etc.
Benefits & Advantages

Vibrating Screen Features
With solidness, high durability, safe operation and easy maintenance, the machine is widely used to screen stones in quarries and also to classify products in mining, construction material, public transport, energy and chemical industry departments.
Driven screening machine adopts simple and dependable flap coupling to instead of universal coupling, which can overcome wearing shortcoming. It installs eccentric vibrator, feeding box which increase effective screen area and extend the screen meshs service life. Application of intermediate axis effectively protects the motors service life. Motor can be mounted on the left side of screen frame or the right side. This series screening machines is seat installation. Screen angle can be adjusted by adjusting the height of supporting.
Application
The vibrating screen with circular motion is specially designed for quarry to separate crushed stone material into different sizes, and is also used as a grading machine in coal dressing, ore dressing, and construction material, electric and chemical industries.

Working Principle
Vibrating screen is mainly composed of case, screen mash, vibrator, damping spring. Through V-belt, motor drives the eccentric block to rotate with a high speed to generate centrifugal force. Then the materials are thrown on and above the screen mash. So the small size products are omitted.
