Vibrating screen is the use of oscillators excited by the oscillating type vibration and work. The upper rotating weight of the vibrator causes the screen surface to produce plane cyclotron vibration, while the lower rotating weight causes the screen surface to produce conical gyrotron vibration, and the combined effect causes the screen surface to produce complex rotational vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and as an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. Adjusting the spatial phase Angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface.
Working principle
The material on the screen surface moves to the discharge end at a certain speed, and the material is screened at the same time. Compared with the above sieve, the productivity and screening efficiency are relatively high. Its disadvantage is poor dynamic balance. It is rarely used in general concentrators, and is replaced by a more reasonable vibrating screen.
Other instructions
1, due to the strong vibration of the screen box, the phenomenon of material clogging the screen is reduced, so that the screen has a high screening efficiency and productivity.
2, simple structure, easy to replace the screen surface.
3, less energy consumption per ton of material screening.
