What is Vibro Sifter?

The Vibro sifter is specially designed to improve the quality of your powder, granule or liquid products for inspection screening of your products, it is ideal for screening incoming ingredients and final production inspection of finished powders, by increasing the number of sieve layers, The product is sieved with different finenesses to achieve precise particle size distribution.

ypes of Vibro Sifter

Vibro Sifter has 1-layer, 2-layer, 3-layer, 4-layer and 5-layer sieve plates, it is suitable for sieving from 2 to 500 meshes, and the products can be classified into 2-6 different specifications through different meshes , and eliminates excessive contamination in various applications. Machine contact parts are made of Q235 carbon steel, SS316L, SS304 stainless steel, etc. Interchangeable screens can be provided according to user requirements, providing various sizes from 400 mm to 2000 mm diameter, allowing 100 to 5,000 kg/hour of production, It depends on the product, mesh size and the feed flow of the machine.

Uses of Vibro Sifter

vibro sifter machine

Classification and screening: Divide the solid particles into different particle groups of equal size. A vibro sifter can accurately and continuously classify 2-6 kinds of specifications at the same time, which is suitable for the classification of granular and powdery materials in multiple industries.

Removal of impurities: Quickly remove small or large particles with a low percentage.

Solid-liquid separation: It can quickly remove insoluble substances in various types of slurries. It can filter up to 100 cubic meters per hour. It is suitable for filtration of liquids such as ceramics and pigments.

Types and Classifications of Vibro Sifter

Mesh size（mesh）:400

Capacity（kg/h）:400-1200

Working Principle of Vibro Sifter

Vibro sifter uses a vertical vibration motor as the excitation source, through the eccentric weights at the upper and lower ends of the vibration motor, the rotary motion is converted into horizontal, vertical and inclined three-dimensional motion, and transmitted to the screen surface, and the material enters the equipment through the feeding port Inside, according to different screening requirements, the materials pass through 1-5 layers of sieves with different meshes. During this process, the bouncing balls under the sieves of each layer continuously hit the sieves, so that the materials can be smoothly Screening, and effectively prevent the material from clogging the sieve hole, the material close to the screen aperture is sieved through the screen, which is under the screen, and the material larger than the screen aperture is discharged from the discharge port of this layer, which is the under screen, complete the purpose of screening or filtering.

BENEFITS OF VIBRO SIFTER

Widely used

Thanks to the simple adjustment of the counterweights on the motor shaft and the three-dimensional vibrations they generate, our vibrating screens allow screening, sorting, dedusting and filtering of a very wide range of products.

Fine sieving

The sieving is as fine as 500 mesh (28 microns), and the filtration is as fine as 5 microns, which can realize high-efficiency screening and filtration. By installing a frequency converter, the vibration speed can also be changed.

High throughput

All incoming materials are automatically discharged, and there is no material stored in the machine. The sieve surface and sieve surface have a larger processing capacity than other types of sieve surface machines, and the processing capacity can reach 100-3300kg per hour.

Mesh anti-clog

Three-dimensional vibration function, designed with automatic cleaning and anti-clogging device (optional bouncing ball, roller brush, ultrasonic cleaning device), minimizing the chance of clogging the screen.

Single or multi-layer sorting

1-5 layers of screens can be installed optionally, and 2-6 products of different specifications can be sorted or filtered at the same time.

Screen replacement is easy

A variety of screen structures can be used according to different needs, and the time for replacing a screen is shortened to 3-5 minutes.
