Circular vibrating screen is a type of screening equipment used for separating materials into different sizes or grades by particle size. 

Circular vibrating screens are commonly used in various industries, including mining, construction, agriculture, recycling, and chemical processing, to name a few. They are versatile, efficient, and capable of handling a wide range of materials and particle sizes.

Five-layer Circular Vibrating Screen

It operates on the principle of vibration and consists of a screen box, screen mesh, vibration exciter, suspension (or support) device, and motor. The circular motion of the screen helps to efficiently separate and classify various materials.

Circular Vibrating Screen Working Principle

Screen Box

The screen box is the main part of the circular vibrating screen and is usually made of steel or other sturdy materials. It contains the screen mesh and supports the materials being screened.

Screen Mesh

The screen mesh is the surface on which the materials are placed for screening. It may be made of metal, rubber, or other materials with specific perforations or openings to allow particles of different sizes to pass through.

Vibration Exciter

The vibration exciter generates the vibrating motion that causes the screen box and screen mesh to vibrate. It can be a single shaft or double shaft type and is usually equipped with eccentric weights to create the necessary vibrations.

Suspension Device

The suspension device connects the screen box to the main structure of the vibrating screen. It allows the screen to vibrate freely while maintaining proper stability and support.


The motor provides the necessary power to drive the vibration exciter, which, in turn, creates the circular motion of the screen.

When the circular vibrating screen is in operation, the motor drives the vibration exciter to rotate rapidly, generating circular vibrations. The materials to be screened are fed onto the screen mesh, and due to the vibrations, they are thrown up and move in a circular motion on the screen surface. As a result, particles smaller than the screen openings pass through the mesh and fall through the screen, while larger particles are carried to the screen's edge and discharged as oversize material.
