Sieving Machine-DAHAN Vibration Machinery

What is meant by sieving machine?

Sieving machines provide a cost-effective solution for almost any separation requirement, including sizing, peeling, grading or product recovery, accurately removing oversized contaminants and agglomerates, or separating the mass components of solids based on particle size Separated from solid and fractionated materials.

ieving machine meaning

To best fit your production line and ensure we can handle any throughput you need, Dahan sieving machines are available in 8 sizes: 400mm, 600mm, 800mm, 1000mm, 1200mm, 1500mm, 1800mm, 2000mm. It allows a throughput of 100 to 5,000 kg/h, depending on the product, mesh size and the feed flow of the machine.

Function of Sieving Machine

1. Screening impurities

Used to remove broken or undersized products such as lumps and other contaminants for final quality checks.

2. Particle size classification

It is to accurately separate particles of different sizes from the product, so that the final material is classified into different sizes. This is usually achieved by passing the product through a grid of up to 5 different aperture sizes.

3. Solid-liquid separation

It can quickly remove insoluble solid substances in various slurries, and can quickly discharge slag. Most are single-layered, but multiple layers can also be used.

4. Batch filtering

Improve product quality and safety by breaking down lumps and filtering out oversized particles, contaminants and debris, ideal for smaller processes, batch production or short production runs.

5. Dehydration

For materials with high mud content and high water content, vibrating screen equipment can be used to achieve desliming and dehydration treatment of materials, which can reach 16-18 tons in 1 hour, but this treatment can only be achieved by special vibrating screen equipment.

Vibro Sifter

Excessive pollutants can be removed accurately, and the separation of 5 different sizes of materials can be achieved in one operation, and the insolubles in various slurries can be quickly removed. This type of screening machine is used to ensure higher quality of the final product.

Ultrasonic Sieving Machine

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).

View
Tumbler Screen

Imitating the principle of manual screening, combining screening (circular motion) with hand screen (parabolic motion), it can be suitable for dry and wet materials, the screening accuracy is 90-95%, and the output is 5-10 times that of vibrating screen. There is no high-speed vibration and will not destroy the shape of the material.

Benefits of Sieving Machine

Wide screening range

Any particle, powder, slurry (mucus) can be screened. The sieving can be as fine as 500 mesh (0.028mm), and the filter can be as small as 5 microns.

Precise sieving

Fully enclosed structure, powder does not fly, liquid does not leak, mesh is not blocked, automatic discharge, there is no storage in the machine, and the grid structure has no dead ends.

Multi-layer screening

It can be used in single and multiple layers at the same time, up to 5 layers, and can carry out 2-6 levels of sorting or filtering at the same time.

Simple screen replacement

The composite screen design has longer screen life and higher efficiency. Two people can change the screen within 3 to 5 minutes, which saves 30 to 60 minutes compared to other types of screens.

Increase flexibility

The compact system is easy to move and can be used in multiple locations on the production line.

Low noise level

Internally sealed with air tightness up to 50 mPa and noise level reduced to 69 dBA.
