Introduction of Vibratory Sieve

Vibratory sieve is used for accurate batch grading or safe screening of powders and liquids, it removes oversized contaminants from your powders and liquids, it also accurately separates your powders and granules It can be divided into different sizes, And can separate up to 6 grades of products in one operation, and our sieves require minimal headroom for easy integration into your production line, widely used in food and beverage, pharmaceutical, powder coating, metal powder, chemical, Agriculture, plastics and other industries.

Vibratory sieve machine

Vibratory sieves are available in diameters of 400, 600, 800, 1000, 1200, 1500, 1800, 2000mm, allowing throughputs from 100 to 5,000 kg/h, depending on the product, mesh size and machine feed flow, and can be tailored to industry needs Choose carbon steel, stainless steel, plastic materials, and can also be designed into gate type, edged type, mobile type, etc.

Function of Vibratory Sieve

Vibratory sieve is a vibratory sieve mechanical equipment that uses the relative motion of the bulk material and the sieve surface to make some particles pass through the sieve holes and divide the coarse material, medium material and fine material into different levels according to the particle size. Its main functions are as follows:

types of vibratory sieve

1. Removal of impurities: high fluidity powder processing, fast removal of large particles or fine powder with low content. Such as food powder, chemical powder, powder coating, pharmaceutical powder, etc.

2. Size classification: Continuously select mixed materials of different particle sizes and classify them into different particle size grades. Can be divided into one, two, three, four and so on. What's more, only one operation can continuously filter up to 5 stages of product separation. Such as grain, feed, fertilizer granules, plastic granules, etc.

3. Solid-liquid separation: quickly remove insoluble solids in various slurries, and remove unqualified impurities or suspended solids in slurries. If fruit juice, soybean milk, oil, grape juice, red wine, etc.

What is the Principle of Vibratory Sieve?

Material Feeding: The material to be sieved is fed onto the top sieve.

Vibration: The sieve machine creates a vertical or three-dimensional vibration. This vibration causes the material to move across the sieve surface.

Particle Separation: Particles larger than the mesh opening of a particular sieve are retained on that sieve, while smaller particles pass through to the next sieve.

Collection: The separated materials are collected in different compartments or containers.

Benefits of Vibratory Sieve

Improve product quality

Eliminates oversizing and contamination in powder or liquid slurries, suitable for sieving from 36 microns to 25 mm.

Multi-layer separation

Up to 5 levels of classification can be provided in one operation for precise particle size distribution, for particle homogenization, etc.

High throughput

Impurities and coarse materials are automatically discharged, and after screening, they can enter the next round of screening work by themselves, allowing a production capacity of 100 to 5,000 kg/hour.

Not easy to block the mesh

The bouncing ball cleaning device is installed under the screen of each layer. By continuously hitting the screen, the material can be screened smoothly and effectively avoid the problem of material blocking the screen.

Totally closed system

Totally enclosed construction protects operator health and safety by reducing dust levels and providing a verifiable OEL5 seal (less than 1µg/m3).

Small footprint

The compact form requires minimal headroom, fits easily into your existing production line, and is available with installation castor wheels for easy movement inside plant if required.

Customized Product Display

Vibratory sieve has professional and unique design for the industry: vibratory sieve such as edge type, gate type, strong type, sealed type, mobile type, silo type, etc. At the same time, there are a variety of grid structure designs, allowing customers to have more choices.

Type	Ultrasonic vibratory sieve	Gated vibratory sieve	Edged vibratory sieve	Vibratory sieve with silo

Features	Sieving on finer meshes (down to 20 microns) without any blocking or blinding of the aperture.	It can be used for a long-term screening operation at one time, and the opening and closing of the control gate can be used to achieve the purpose of good screening.	On the basis of ordinary vibratory sieve, the feeding port is enlarged, and the special angle is designed to prevent liquid splashing.	By adjusting the butterfly valve in the silo, the flow of the material is controlled, saving labor without the need for workers to continuously feed the material.
Application	It is suitable for fine powder materials with static electricity, adsorption and light specific gravity, such as graphite powder, phosphor powder, metal powder, etc.	It is mostly used for the screening of ultra-light and ultra-fine materials, such as traditional Chinese medicine powder, pollen and other industries.	Widely used in paint, water filtration, pulp filtration and other industries.	It is used in the environment where the screening place is not fixed, it is convenient for users to move, and it can meet the work needs of different places.
