Introduction of Vibrating Sifter

Vibrating sifter is a vibrating separator for separating powders, granules and liquid slurries. It accurately removes excess contaminants and is ideal for inspecting and screening your materials on the secondary side of your production equipment, from the primary side to the finished product. . You can separate 5 different sizes of materials in one operation. It allows production throughputs from 100 to 3300 kg/h, depending on the product, mesh size and feed flow of the machine. It is suitable for screening from 2 to 500 mesh.

Vibrating sifter models are available in diameters of 400mm, 600mm, 800mm, 1000mm, 1200mm, 1500mm, and 1800mm, and can also be specially customized for you.

Types of Vibrating Sifter

Ordinary Vibrating Sifter

It makes the material move on the screen through the action of vibration force, and separates or sorts the particles according to their size.

Mesh size（mesh）:2-500

Capacity（kg/h）:100-3300
Ultrasonic Vibrating Sifter

On this basis, an ultrasonic vibration system is introduced to use the effect of ultrasound to perform more fine screening and grading of materials.

Mesh size（mesh）:635

Capacity（kg/h）:100-5000
Inline Vibrating Sifter

Rough inspection, screening and impurity removal of powders and granules, ideal for screening incoming ingredients and final production inspection of finished products

Mesh size（mesh）:140

Capacity（kg/h）:3000-30000
Sigle-layer Vibrating Sifter

It has only one layer of screen and two discharge ports, and has a simple structure. It is mainly used to screen the material once, and divide the material into two parts, which are larger than the screen hole and smaller than the screen hole.
Double-layer Vibrating Sifter

It has two layers of screens with different apertures and three discharge ports, which can divide the material into three parts at one time, namely, larger than the aperture of the upper screen, between the apertures of the two screens, and smaller than the aperture of the lower screen.
Multi-layer Vibrating Sifter

It has multiple screens, and the screen aperture decreases gradually from top to bottom. Up to 4 layers of screens with different mesh sizes can be installed, which can divide the material into multiple particle sizes at one time and realize multi-stage screening.

Working Principle of Vibrating Sifter

After the vibrating sifter is started, the heavy hammer is driven by the motor to vibrate, and the screen body produces horizontal, vertical, and inclined three-dimensional motion, so that the material is thrown up on the screen and rotates outward from the center to the discharge port to be discharged. The material is discharged in the screen. During the movement of the net, fine particles or liquids pass through the screen, and the materials are screened, classified or filtered by selecting and installing the corresponding screen and the number of screen layers. The sorted materials are automatically discharged from their respective outlets.

Benefits of Vibrating Sifter

Efficient Separation

Vibrating sifters excel at separating materials with high efficiency. The rapid, oscillatory motion of the screen ensures precise particle separation, allowing for accurate size classification.

High Throughput

These machines can handle large volumes of material, making them ideal for high-production environments. They are designed to process materials continuously, maximizing productivity.

Versatility

Vibrating sifters are versatile and can be adapted to handle a wide range of materials, including powders, granules, and small particles. They are suitable for industries such as food processing, pharmaceuticals, chemicals, and mining.

Precise Screening

With adjustable vibration intensity and screen mesh sizes, vibrating sifters can achieve precise screening results. This ensures that the separated materials meet specific quality standards.

Dust Containment

Some vibrating sifters come with dust containment systems, which help maintain a clean working environment and prevent product contamination.

Reduced Downtime

Regular maintenance and cleaning of vibrating sifters can help prevent clogging and ensure continuous operation, reducing downtime in production processes.

Vibrating Sifter Customization

Model	Edge-added type	Gate type	Filtration type	High frequency type	Gas protected type	Silo Type
Image
Application	Enlarged inlet design to prevent material splashing, easy to observe the screen, suitable for filtering liquids	The gate type design can extend the screening time, improve the screening accuracy, and allow more materials to enter and less to exit	Designed for filtering liquids, suitable for slurries with small processing volumes and few impurities	Using high frequency vibration motor (3000 rpm) as the excitation source, it is suitable for filtering high concentration slurries, such as ceramic glazes, etc.	During the screening process, inert gas is introduced into the screen box to form a closed gas environment. It is mainly used to screen some materials that are sensitive to oxygen or easily oxidized, such as metal powders, 3D printing materials, etc.	It can realize continuous feeding and screening of materials by directly installing the silo on the vibrating screen, greatly improving production efficiency. It is suitable for screening various powdery and granular materials.

Structure of the Vibrating Sifter

Screen Frame: The screen frame provides support for the screen panels or mesh and holds them in place. It is usually made of steel or other sturdy materials to withstand the vibration and screening process.

Screen Panels or Mesh: The screen panels or mesh are the main screening surface where the material is separated based on particle size. They are typically made of woven wire mesh, perforated plates, or synthetic materials with specific opening sizes to allow undersize particles to pass through.

Vibrating Motor: The vibrating motor is responsible for generating the vibration that moves the screen surface. It is usually mounted on the side or underneath the screen frame. The motor's rotation or eccentric weight creates the necessary vibration for the screening process.

Support Structure: The support structure provides stability and rigidity to the vibrating sifter. It may consist of a base frame, legs, and cross beams. The support structure is designed to minimize vibrations transmitted to the surrounding environment.

Drive System: The drive system transmits power from the motor to the screen frame, causing it to vibrate. It typically includes a motor, belts or gears, and pulleys or shafts.

Springs or Rubber Mounts: Springs or rubber mounts are used to isolate and dampen vibrations, ensuring smooth operation and reducing noise transmission.

Discharge Chutes: The vibrating sifter may have separate discharge chutes for the undersize and oversize fractions. These chutes direct the separated fractions to their respective outlets or collection points.

Control Panel: Some vibrating sifters are equipped with a control panel that allows operators to adjust the vibration intensity, screen inclination, and other operating parameters.
