What about Movement Forms of Vibration Screen?

Vibrating screen which is also can be called linear vibrating screen has the reliable operation, lower energy consumption, lower noise, long lifespan, stable vibration, high screening efficiency and so on. The basic theory of it is mainly by the hammer (uneven hammer) installed in the lower end of the motor shaft, the rotary motion of the motor into a horizontal, vertical, three-dimensional movement of the tilt, then this movement is conveyed to the screen surface. The traveling direction of the raw material can be changed if the angle of the upper and lower portion of the hammer is changed.

Linear vibrating screen adopts dual vibrating motors. When the two motors do synchronized and reverse rotation, the generated centrifugal force is offset in the parallel direction of motor axis, and stacked together as a resulting force in the perpendicular direction of the motor axis. Hence, the screen trajectory is a straight line. The linear vibrating screen also can be applied to the screening and grading of powder and granular materials, which is widely used plastics, chemical industry, building materials, food, carbon, chemical fertilizer industry and so on.

In vibrating screen, the screen surface movement form of vibration screen in China has a circular vibration, linear vibration and several elliptical vibration. Circular vibration mode can make fully loose material and blocking resistance is strong, but the projectile Angle is large, oversize material transmission capacity is small. In order to improve the transmission capacity, to increase the screen surface dip Angle, which makes the screen size is not too strict, layer acceleration in feeding, reduce the close to the screen hole size of the particles on the sieve surface discharge end through sieve. Linear vibration mode cannot make loose and rearrange the material thoroughly, is not easy to close to the screen surface and solid fine grained material through sieve, has blocked mesh particle is not easy to throw, worsen the screening process.
