A rotary vibrating screen is a common circular screening device. Its unique three-dimensional composite motion pattern combined with a simple installation design enables it to achieve high screening efficiency, high screening accuracy, and easy cleaning, making it an indispensable vibrating screening device in modern industry. It is widely applied in precision screening across various industries such as chemicals, food, pharmaceuticals, metallurgy, construction materials, abrasives, ceramics, papermaking, and environmental protection. This article will mainly explain its working principle and China rotary vibrating screen suppliers.
Working Principle of the Rotary Vibrating Screen
Its primary working principle lies in its unique three-dimensional motion pattern. Materials undergo complex movements within the screen, enabling them to efficiently and rapidly pass through the screen mesh to achieve screening results.
Power source: It is powered by one or more vertical vibrating motors. When the motor is started, the eccentric weights at both ends of the rotor generate rapid centrifugal force to produce power.
Three-dimensional motion mode: The eccentric force generated by the eccentric weights causes the screen mesh or screen machine to move in both the horizontal and vertical planes. The horizontal motion is nearly circular, and when combined with the vertical motion, it forms a three-dimensional motion pattern.

Working Process:
- Start the screening machine; the motor provides the power source, causing the rotary vibrating screen to begin operation.
- Material is fed into the screening machine through the feed opening; the feeding process must be uniform.
- Under the influence of three-dimensional motion, the material begins to spread, layer, flip, and jump.
- During the multi-layer screening process, materials smaller than the screen mesh openings pass through the first layer of the screen, while materials remaining on the screen are discharged through the discharge port, completing one screening cycle.
- Materials that pass through the first layer undergo another screening on the second layer of the screen, and so on. The rotary vibrating screen can perform up to five layers of screening, meaning we can obtain five different sizes of materials in a single process.
- This three-dimensional motion effectively addresses screen clogging and the screening of sticky materials. We can also place bouncing balls in each layer to maximize cleaning and screen permeability.
