The vibrating screening machine works by using the reciprocating vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And 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.
The vibrating screening machine is mainly composed of a screen box, a vibrator, a suspension (or support) device and an electric motor. The motor drives the main shaft of the exciter to rotate through the V-belt, and the screen box vibrates due to the centrifugal inertial force of the unbalanced weight on the exciter. Different amplitudes can be obtained by changing the eccentric weight of the exciter.
The main advantages of vibrating screens:
1. Due to the strong vibration of the screen box, the phenomenon of material blocking the screen hole is reduced, so that the screen has high screening efficiency and productivity.
2. The structure is simple, and the screen surface is convenient to replace.
3. Less electric energy is consumed per ton of materials screened.
working principle
Sieving is the process of dividing the broken bulk materials with different particle sizes through the single-layer or multi-layer sieve surface with evenly distributed holes multiple times, and dividing them into several different levels. The particles larger than the sieve hole remain on the sieve surface, which is called the oversize of the sieve surface, and the particles smaller than the sieve hole pass through the sieve hole, called the undersize of the sieve surface. The actual screening process is: after a large number of broken materials with different particle sizes and mixed thicknesses enter the screen surface, only a part of the particles are in contact with the screen surface. The gap in the gap is further expanded, and small particles take the opportunity to pass through the gap and transfer to the lower layer or the conveyor. Due to the small gap between the small particles, the large particles cannot pass through, so the particle groups that were originally arranged in a disorderly manner are separated, that is, they are layered according to the size of the particles, forming an arrangement rule that the small particles are at the bottom and the coarse particles are at the top. The fine particles that reach the sieve surface, those smaller than the sieve holes, pass through the sieve, and finally realize the separation of coarse and fine particles, and complete the screening process. However, there is no sufficient separation, and generally a part of the undersize remains in the oversize during sieving. When the fine particles pass through the sieve, although the particles are all smaller than the sieve holes, they have different degrees of difficulty in sieving. For particles with similar material and sieve hole sizes, it is more difficult to pass through the sieve, and it is even more difficult to pass through the particle gap in the lower layer of the sieve surface.
