Introduction
Rotary vibrating screen is designed as a high-precision screening machinery, it is composed of a upper cover, a screen box, a base and a vertical motor with eccentric weight installed at two ends. Rotary vibrating screen can be produced in horizontal, vertical, inclined motions by adjusting the upper and lower eccentric weight. Diameter also can be ranged from 400mm to 2000mm, with single or multiple screening decks, material can be total carbon steel, total stainless steel or material contact parts are stainless steel according to different product.



Working Principle
The vibration is accomplished by eccentric weights on the upper and lower ends of the motion-generator shaft. The direction of the eccentric weights can change its rotational mode,rotation of the upper weight creates vibration in the horizontal plane, which causes material to move across the screen cloth to the periphery,while the lower weight acts to tilt the machine, causing vibration in the vertical and tangential planes. The trajectories of materials on the screen can be changed by adjusting the phase angle of upper and lower weights.

Application
Rotary Vibrating Screen is widely used in many industries, covering food, chemical, ceramic, metallurgy, pollution treatment and so on, dealing with various kinds of materials.

Advantages and Features
1.Various material separation range- power or particle,wet or dry, heavy or light,coarse or fine, hot or cold.
2.Various size range-available diameter from 400mm to 2000mm,mesh size can reach 500 mesh ( 0.028 mm).
3.Environmentally Friendly- Fully enclosed structure,no dust pollution,improve working conditions for operators as well.
4.Quick Screen Changes-Quick release device is provided to replace the screen with 5 minutes.
5.Automatic screen cleaning-bouncing balls keep screen openings clean and maintain a good efficiency.
6.Customized order- Rotary vibrating screen can be customized according to customer’s demand.
7.Unique design-Mature technology,compact and simple structure,convenient installation and maintenance.
8.Wide application-Rotary vibrating screen is applicable to any powder, granule, particle and mucus.
