Vibrating Sieve-DAHAN Vibration Machinery

Introduction of vibrating Sieve

Circular Vibrating Sieve

Vibrating sieve uses an unbalanced force to create vibrations that move material through the sieve at a faster rate. It is used to remove oversize, agglomerates and foreign objects from powders, granules or liquids. It can also be used for grading of different sizes of the same product. , which can provide up to 5 grades of classification in one operation, so as to achieve accurate particle size distribution. It is suitable for dry or wet applications such as flour, powder coatings, pharmaceutical powders, coffee beans, spices and more.

Vibrating sieve can be divided into 1-5 layers, carbon steel and stainless steel can be selected

Different Types of Vibrating Sieve

Circular Vibratory Sifter

Remove impurities in the material, and classify the mixed powder and particles into different sizes as you require.

Ultrasonic Vibrating Sieve

Ultrasonic frequencies are used to vibrate the screen so that the mesh does not clog and the powder is easier to screen. The system increases screening capacity by a factor of 10, increasing productivity while allowing separation accuracy down to 20m (#635 mesh).

Working Priciple of Vibrating Sieve

Vibrating sieve is composed of dust cover, feed inlet, screen, grid frame, vibrating motor, discharge outlet, feed the material to be separated through the hopper (small hole on the top of the vibrating sieve), the screen/sieve will start to vibrate, Then, the material fed into the hopper will pass through the sieve according to the particle size, the particles larger than the sieve hole stay on the sieve surface, called the oversize, and the particles smaller than the sieve hole pass through the sieve hole, called the undersize, and finally The separation of coarse and fine particles is realized, and the screening process is completed.

angle adjustment

During the working process, the original phase angle can be adjusted through the eccentric block according to the change of the screening material or the change of the motion track.

The angle adjustment of the eccentric block is as follows:

1.When the upper and lower eccentric blocks of the motor are adjusted to 0 degrees, the materials are scattered from the middle to the surroundings, which is used to screen a large number of rough materials.

2.When the upper and lower eccentric blocks of the motor are adjusted to 30 degrees, the material is dispersed in a swirl shape, which is used to screen general materials.

3.When the upper and lower eccentric blocks of the motor are adjusted to 45 degrees, the material is dispersed in a rapid swirl shape, and the movement track of the material on the screen surface is longer, which is mainly used to screen fine materials.

4.When the motor is adjusted up and down to 90 degrees, the material is concentrated from the surrounding to the middle, and is filtered by wet type.

Benefits of Vibrating Sieve

Sieve to 500 mesh

Improve product quality by eliminating oversized contaminants in powder or liquid slurries, it is suitable for sieving from 0.025mm to 25 microns (500 mesh).

6 levels separation

Up to 5 layers of sieves are allowed to separate up to 6 different sizes of one product for precise particle size distribution for particle homogenization.

Continuous operation

The direction of the discharge port can be adjusted arbitrarily, and the coarse and fine materials are automatically discharged, which can be automated or manually operated.

Remove dust

Unique grid design (sub-mother type), long-term use of the screen, easy to change the screen, only 3-5 minutes, simple operation, easy to clean.

Small footprint

The compact form requires minimal headroom and can easily fit into your existing production line

Noise as low as 60 decibels

The rubber suspension system reduces mechanical noise and ensures quiet operation down to 60 decibels.

Vibrating sieve models have diameters of 300mm, 450mm, 500mm, 600mm, 800mm, 1000mm, 1200mm, 1500mm, 1800mm, 2000mm, and can also be customized for you.

1.Machine material: carbon steel, stainless steel (special for food and pharmaceutical industry), plastic (resistant to strong acid and strong alkali corrosion) can be selected according to the application requirements.

2.Machine size: You must fully understand the size of the equipment you use, and secondly, understand the processing capacity per hour, up to 3TPH capacity, and one machine is connected to one production line. The maximum output of the 1200-1 model can reach 3 tons per hour (conditions: 2mm mesh is used to treat foundry sand, and the underscreen material accounts for 95%).

3.Number of layers: refers to the number of layers of screen installed in the sieve machine. The vibrating sieve of 1 layer refers to the installation of a mesh frame inside the sieve machine. Usually, a mesh frame is only equipped with a mesh of one specification and has two outlets. , one outlet for coarse material, one outlet for fine material, three vibrating sieves for two layers, and so on. For example, if the user needs to produce two kinds of materials at the same time, he can use a screening equipment with one layer and two outlets.

4.Mesh size: The higher the screening accuracy, the cleaner the screening results. For example, if the user needs materials with a particle size of 1~2mm, the screening results of 1~2mm materials include materials smaller than 1mm or materials larger than 2mm.
