Introduction of Circular Vibratory Sifter

Circular Vibratory Sifter

Circular vibratory sifter is a circular unitary gylatory screen with a wide variety of uses for separating the mass composition of solids from solids and grading materials according to particle size., due to the simple adjustment of the counterweights on the motor shaft and the three-dimensional vibrations they produce, It can screen, classify, dedust and filter all kinds of products, even fine products can achieve good results.

types of circular vibratory sifter

On each circular vibratory sifter you can install 1 to 5 separation stages, resulting in 2 to 6 product classifications, suitable for 2-500 mesh sieving, various models (from Ø 400 to Ø 2200 mm) can satisfy For any type of requirements, the processing capacity of 100-3300kg/h is allowed, and various models such as carbon steel, 304 stainless steel and plastic are complete. According to the needs of special industries, it can also be designed as gate type, edge type and other models.

Function of Circular Vibratory Sifter

circular vibratory sifter can handle dry, wet, lumpy, viscous and other difficult-to-handle materials

1.Removal of impurities: high-flow powder material processing, quickly remove large particles or fine powder with little content.

2.Grading and screening: Continuously select mixed materials of different particle sizes, and classify them into different particle size grades. The circular vibratory sifter can be divided into one layer, two layers, three layers, four layers, etc. The more, up to 5 stages of product separation can be continuously filtered in just 1 operation.

3.Solid-liquid separation: Quickly remove insoluble solids in various slurries, and remove unqualified impurities or suspended substances from the slurries.

Working Principle of Circular Vibratory Sifter

Circular vibratory sifter uses a vertical vibration motor as the excitation source. The eccentric weight at the upper and lower ends of the vibration motor converts the rotational motion into a horizontal, vertical, and inclined three-dimensional motion, and transmits it to the screen surface of the rotary vibrating screen; The feed inlet enters the equipment. According to different screening requirements, the material passes through the 1-5 layers of screens with different meshes. In this process, the cleaning devices located under the screens of each layer continue to hit the screen. The mesh enables the materials to be screened smoothly and effectively avoids the problem of material blockage. The materials of different meshes pass through the screens of the corresponding meshes of each layer or are discharged through the outlets set on each layer, and finally realize the screening or Purpose of filtering. Adjusting the phase angle of the upper and lower ends of the motor can change the movement trajectory of the material on the screen surface.

Adjustment Method of Upper And Lower Weight of Circular Vibratory Sifter

2Adjustment method of upper and lower weight

Circular vibratory sifter uses a vertical motor as the excitation source. The eccentric hammers installed on the top and bottom of the motor turn the rotary motion into vertical, horizontal and inclined three-dimensional motion, and transmit the motion to the screen surface. By adjusting the two eccentric hammers The phase angle between them can change the motion path.

1. When the angle between the upper and lower eccentric blocks of the motor is adjusted to 0 degrees, the material will be dispersed from the middle to the surrounding, which is used to screen a large number of rough materials.

2. When the angle between the upper and lower eccentric blocks of the motor is adjusted to 15 degrees, the material will be dispersed in a vortex, which is used to screen general materials.

3. When the angle between the upper and lower eccentric blocks of the motor is adjusted to 45 degrees, the material will be dispersed in a rapid vortex shape, and the movement track of the material on the screen surface is the longest, which is mainly used to screen fine materials.

4. When the angle between the upper and lower eccentric blocks of the motor is adjusted to 90 degrees, the material will be concentrated from the surrounding to the middle, which is suitable for wet filtration.
