Circular Vibrating Screen

Vibrating screen is the essential screening equipment in all kinds of sand production lines, which is mainly used for the screening of dry materials in metallurgy, coal, ore and other materials. It is widely used for products classification in mining, building materials, transportation, energy, chemical industry and other industries. Vibration screen also has other names, such as vibratory screen and vibrating screen machine.

Vibrating Screen is used to separate materials into various sizes for further processing or for end use dependent on your conditions. The material is separated by passing through a vibrating “screen box” which has a number of different sized screens, or meshes, through which the material falls through like a sieve, and to the attached conveyors to become end products.

NT-YK Circular vibrating screens can be divided into 2 decks vibrating screen, 3 decks vibrating screen and 4 decks vibrating screen.

Circular Vibrating Screen

The difference between circular vibrating screen and linear vibrating screen is that circular vibrating screen is doing circular motion, which is a new type of multi layers and efficient screening equipment.


Vibrating screen is mainly composed of the screen box, vibration exciter, suspension (or supporting) devices, electric motors, etc. Motor drives the spindle to rotate through the belt. Due to the unbalanced centrifugal inertia force of heavy objects in the vibration exciter, the vibrating screen box will get vibration force. Changing the exciter eccentric weight can get different amplitude.

Circular vibrating screen is single-axis circular-movement inertial vibrating screen, whose working depends on inertial motor and inertial strength produced by eccentric plate.

Because of the vibration of screen box, the materials are thrown out, so that materials of certain size go through the screen mesh, and the screening aim is realized. Since the magnetic exciter is installed on the gravity center of screen box, the upper of long elliptical axis at inlet end is in the same direction with the outlet, which favors the spread of materials which are at the screen box.

However, the upper of long elliptical axis at outlet end is opposite to the direction of the outlet, which can reduce the movement speed of materials, and help the difficult-screened materials go through the screen mesh. What’s more, the effective area of screen is increased because of the elliptical screen surface; as a result, the processing capacity is increased.



It adopts the cylinder type eccentric shaft vibration exciter and partial block adjusting amplitude, which has convenient use and maintenance.


Its spring steel woven wire screen or punching sieve has long service life, which is not easy to cause blockage.


Rubber vibration isolation spring has long service life, low noise and stable resonance zone.


Reliable structure, strong exciting force, high screening efficiency.
