Circular vibrating screen, this efficient screening equipment, is widely used in many industries such as mining, building materials, chemicals, and food. Today, let us take a deeper look at the charm of circular vibrating screen.
What is a circular vibrating screen?
Circular vibrating screen is a screening equipment that uses a vibrating motor to drive the screen box to make the material move in a circular or elliptical shape on the screen surface. Its vibration trajectory is projected as a circle on the horizontal plane and an ellipse on the vertical plane.

Working principle
The working principle of the circular vibrating screen is based on vibration screening technology. Its core component is a vibration motor or an eccentric shaft exciter. The rotation of the motor generates an exciting force to drive the screen box to vibrate in a circular trajectory. The material is subjected to the impulse transmitted by the screen box on the screen surface, producing a continuous throwing motion, and particles smaller than the screen hole pass through the screen, thereby achieving classification.
Structural composition
The circular vibrating screen is mainly composed of a screen box, a screen, a vibrator, a vibration damping spring device, a chassis, a suspension or support device, and a motor. The vibrator adopts an eccentric structure, and the screen mesh can be selected from spring steel woven screen mesh or punched screen plate according to the needs.
Advantages and characteristics
High efficiency: the material moves in a circle on the screen surface, the screening speed is fast, and the processing capacity is strong.
Simple and reliable structure: the vibrator has a simple structure, convenient maintenance, and a long service life.
Wide range of applications: it can handle a variety of materials such as powder and granules, and has strong adaptability.
Energy saving and environmental protection: low operating noise and low energy consumption.
Easy maintenance: the core components are made of high-strength materials, which are wear-resistant and durable, reducing the maintenance frequency.
Application areas
Circular vibrating screens are widely used in the following industries:
Mining: used for screening, grading and dehydration of ores.
Building materials: used for screening of materials such as sand, gravel, cement, etc.
Chemical industry: used for screening of chemical powders and particles.
Food: used for screening of materials such as flour and starch.
Metallurgy: used for screening of slag and slag.
Environmental protection: used for sludge dehydration and solid waste classification.
Conclusion
The circular vibrating screen has become an indispensable screening equipment in modern industrial production due to its high efficiency and reliable performance. Whether it is mining or building materials, it is a powerful assistant for those companies pursuing efficient production.
