Round Vibrating Sifter

Introduction of round vibrating sifter

Round vibrating sifter is a vibrating screen that integrates classification, impurity removal and filtration. It is mainly made of carbon steel, stainless steel and all stainless steel. It has a single-layer or multi-layer design. The screen surface can reach 5 layers. Screen 6 kinds of materials with different particle size specifications.

During the screening process of the Round vibrating sifter, the material is distributed evenly on the screen (because the material is fed from the center, it will move in a spiral and gradual trajectory). The material can be determined on the screen by adjusting the tangential angle and rotation speed. The length of the residence time on the surface, so the accuracy of the material and the processing capacity are controllable with a circular vibrating screen.

Benefits of round vibrating sifter

1. It is suitable for a wide range of materials, and can be sieved to 500 mesh or 0.028mm powder and granules, and liquid materials can be filtered to 5 microns.

2. Equipped with a bouncing ball cleaning device, which can achieve the purpose of cleaning the screen by continuously hitting the screen without blocking the screen. For viscous and electrostatic materials, the ultrasonic cleaning device can be used.

3. Fully enclosed structure, no dust spillage, improve working environment.

4. It can sieve 1 to 5 layers of screens, and can carry out 2 to 6 levels of sorting or filtering at the same time.

5. Impurities and coarse materials are automatically discharged, and continuous operation is possible.

6. The discharge port can be rotated 360°, which is easy to operate.

Working principle of round vibrating sifter

Round vibrating sifter uses YZUL vertical vibration motor as the excitation source. The eccentric weight on the upper and lower ends of the vibration motor converts the rotational motion into horizontal, vertical, and inclined three-dimensional motion, and transmits it to the screen surface of the rotary vibrating screen; the material passes through The feed inlet enters the equipment. According to different material screening requirements, the material passes through 1-5 layers of sieving with different mesh metal woven screens. In this process, a cleaning device is located under the screens of each layer. (Bouncing ball) Continuously hitting the screen through frequency vibration, so that the materials on the screen can be smoothly screened through the screen, and effectively solve the problem of material blockage. After the materials of different meshes pass through the screens of the corresponding meshes of each layer It is discharged at the discharge port of each layer, and fina l ly achie ves the purpose of screening and removing impurities or filtering and grading.

Structure of round vibrating sifter

Round vibrating sifter is composed of inlet, dust cover, outlet, beam ring, screen, counterweight, upper weight, vibrating body, vibration motor, spring, lower weight, base and other parts.

Dust cover: to prevent the escape of dust.

Vibration motor: Vertical vibration motor is used, and the motor power can be selected from 0.18KW to 4.0KW. (The larger the diameter of the device, the greater the power of the motor used). For some special industries, explosion-proof vibration motors can be equipped.

Screen frame: Constrain the material to make the material produced within a certain range. Common materials are Q235 carbon steel and 304 stainless steel, and the thickness of the material is 2.0mm~3.0mm.

Beam ring: connect the bottom cone and the screen frame, the upper and lower screen frames, and also play a role in preventing material leakage.

Screen: The parts contacted by the material, the commonly used material is 304 stainless steel woven mesh.

Punching plate: Lift the screen to extend the service life of the screen. The commonly used material is 304 stainless steel.

Net cleaning device: It can be divided into three types of net cleaning devices: bouncing ball, ultrasonic, and rotating brush. Users can choose reasonably according to different production processes.

Bottom bucket: the part that supports the screen body and carries the vibration motor, the thickness is 3mm~6mm, and the thickness is also determined according to the diameter of the equipment.

Vibrating plate: It has the function of fixing the vibrating motor and connecting the screen body. The plate used is Q235 carbon steel with a thickness of 4mm~6mm.
