vibrating screen working principle

According to motion theory, screening machines can divide into linear, circular, horizontal, eccentric shaft vibratory screens and inclined screen.
The vibratory screening machine is to utilize reciprocating vibration of the vibration generator produced. The processing of the screen separates the different size material by a single- or triple-deck screen. That is, according to the size of particles to separate. The underlayer is a small material, and the upper layer is coarse particle material. In the end, the coarse and fine particles are separated and the screening process is completed.

Some features highlight:

  • Screen feed: mixture of coarse and ifne particles
  • Material stratification: Nearsize and oversize particles at the top of bed
  • Separate screening: nearsize particles in contact with screen surface
  • Stratified region experience a high rate of screening

Types of screen mesh material

vibrating screen working

The single deck, double deck, and multilayer vibrating screen is the basis of the numbers of the layers. Because of the different screening materials, we also call it gravel screen, sand screen machine, aggregate screening, wet vibratory screens.

features and advantages

  • The material screen drip line is long and has many screening specifications.
  • The eccentric block as an exciting force, a strong exciting force.
  • Sieve beams and sieve box connected by high strength bolts, no welding.
  • Sieve machine has the advantages of simple structure and convenient repair.
  • The small amplitude, high frequency, high dip structure, so this machine is of high efficiency, maximum, long life, low power consumption, low noise.

Factors may affect screening result

1. The shape of the particle and screen size

Most screening material is cylinder or anomaly, and the screen size has both circular and rectangle. The shape of the material granule touch screen for particle whether passed has a big effect. The rectangle screen is good for the circular particle, and the circular screen for irregularity.

2. The opening rate of the screen surface

The more opening rate of the screen surface, the more passed.

3. The thickness of materials

If the materials are too thickness, the upside will difficult to pass. If the materials are too thin, the screening products will low, also undesirable.

4. The state of screen motion

The practice shows that level or vertical repeating motion of the screen, The screening effect is not good. The vibratory screeners combined the two motion is better.

5. The peculiarity of the material
All the size, humidity, friction and flowability of material will affect the screen. The humidity higher, friction bigger, flowability too bad, so the passing rate lower.
