Description

Vibrating screen is also called vibration screen, sand vibrating screen and rotary vibrating screen, which works by the repeated spiral vibration produced by the shock excitation of vibrator. The upper rotation heavy hammers on the vibrator make the screen surface produce plat spiral vibration, and the lower rotation heavy hammers will make the screen surface produce cone spiral vibration, and the compound effect is to make the screen surface produce repeated spiral vibration. The vibration locus of the materials is a complicated space curve whose projection on the horizontal plane is a circle and an oval on the vertical plane. Adjusting the exciting force of the upper and lower rotation heavy hammers can change the amplitude and adjusting the space phase angle of them can change the curve shape of the movement locus of the screen surface and change the movement locus of the materials on the screen surface.

 

Main Types of Vibrating Screen

 

Vibrating screen used in mining industry is mainly divided into two types: circular vibrating screen and linear vibrating screen.

 

Features of Vibrating Screen:

1.Stable vibration, reliable operation, long duration;

2.Simple structure, convenient replacement of screening sifter;

3.Low power consumption for per ton;

4.It can adjust the excitation force, control and change the flow at any time, which has convenient adjustment;

5.The vibration motor is the vibration source, which has low noise, low power consumption and simple structure;

6.Reliable operation, convenient installation and adjustment, light weight, small volume, convenient maintenance;

7.Due to the strong vibration of screening boxes, the blocking phenomenon of materials has been reduced, so that the screen has high screening efficiency and productivity.
