Rotary Vibrating Screen-DAHAN Vibration Machinery

Introduction of Rotary Vibrating Screen

Screening principle diagram

Rotary vibrating screen is also called rotary vibrating screener, used for safety screening to eliminate foreign matter, classification of different particle sizes in the same product, and the process of solid-liquid separation, using customized layered screen and powerful 3D vibration motion to pass different meshes With the external output and stackable design, this ingenious and simple machine can continuously filter up to 5 stages of product separation in just 1 operation.

Product classification

Our rotary vibrating screens are available in a variety of sizes, suitable for smaller and larger scale operations from Ø400 to Ø22000, allowing throughputs from 100 to 5,000 kg/h, due to the working principle of their application being three-dimensional motion, Compared to traditional screening machines, this vibrating screen produces 3 times more vibration and provides higher throughput in ultra-fine screen meshes.

Principle of Rotary Vibrating Screen

rotary vibrating screen working priciple

Rotary vibrating screen uses YZUL vertical vibrating motor as the excitation source. The rotating motion is converted into horizontal, vertical and inclined three-dimensional motion through the eccentric weights at the upper and lower ends of the vibrating motor, and is transmitted to the screen surface of the rotary vibrating screen; It enters the equipment through the inlet. According to different material screening requirements, the material passes through 1-5 layers of different mesh metal woven screens. In this process, the cleaning screen is located under the screens of each layer. The device (bouncing ball) continuously hits the screen through frequency vibration, so that the material on the screen can be smoothly screened through the screen, and effectively solves the problem of material blockage. The materials of different meshes pass through the screens of the corresponding meshes in each layer. Then it is discharged at the discharge port of each layer, and finally achieves the purpose of screening and removing impurities or filtering and grading. Adjusting the phase angle of the upper and lower ends can change the movement trajectory of the material on the screen surface.

Benefits of Rotary Vibrating Screen

Fine filter

In the rotary vibrating screen, the sieve cloth is a stainless steel wire woven mesh, and the smallest can reach 600 mesh (0.02mm). The counterweight rapid adjustment system can control and adjust the material movement on the sieve cloth, and maintain a long screening time to complete the fine screen.

high throughput

Horizontal, inclined, vertical 3D vibratory motion for higher vibrations, 3 times higher throughput through precise screening, it allows throughputs from 100 to 5,000 kg/h depending on product, mesh size and machine feed flow.

Prevents mesh blinding

Equipped with a professional screen cleaning device, the screen will not be blocked in the process of screening materials, and the screening blockage rate is less than 10%, which greatly improves the screening output and screening efficiency of the screen.

6 levels

On each shaker you can install 1 to 5 separation stages, resulting in 2 to 6 product fractions. to achieve precise particle size distribution.

No dust pollution

The rotary vibrating screen can be used in conjunction with a hose to achieve full sealing without dust, floating powder and liquid splashing. It is very suitable for sanitary production lines and dust-free workshops, and it is also very helpful to protect the health of your employees.

good adaptability

The height of the machine can be specially customized according to customer requirements. The discharge port can be placed 360 degrees, which is convenient for other equipment in the production line. It adopts IP65 protection grade motor, that is, dust and water resistance, heat resistance and oil resistance, and can deal with ultra-fine dust and liquid. Filtration separation, high and low temperature and other harsh environments.
