Swing Vibrating Screen

What is a swing vibrating screen?

Swing Vibrating Screen is a high-precision fine-particle screening equipment, also known as a reciprocating vibrating screen. It achieves material screening through a special motion mode. The screen box, driven by the motor, performs a complex plane gyratory motion. This motion trajectory is similar to an ellipse, causing the material to produce a regular, three-dimensional tumbling motion on the screen surface.

What is the difference between a swing vibrating screen and a vibrating screen?

How does the swing vibrating screen work?

Swing vibrating screen mainly uses the difference between the particle size of the material and the aperture of the screen to screen. When the screen box starts to move, the material is thrown up and rolls, slides and jumps on the screen surface. In this process, smaller particles can pass through the screen holes, while larger particles are left on the screen surface and gradually move toward the discharge port as the screen box moves, thereby achieving the separation of materials of different particle sizes.

What types of swing vibrating screens are there?

Circular Swing Vibrating Screen: The screen box moves in a circular motion, which is suitable for screening materials with smaller particle sizes and has high screening accuracy. The screening efficiency is generally 93%~95%, which is suitable for grading, stripping, dehydration and other purposes.

Square swing vibrating screen: The screen box moves back and forth in a straight line, and the material is thrown on the screen surface many times to achieve screening. The processing capacity is several times that of the traditional vibrating screen, which is suitable for screening sand, gravel, aggregates, etc.

Advantages of Swing Vibrating Screen

1. High-precision screening: The movement of the swinging screen allows the material to fully roll and jump on the screen surface. 

2. High processing capacity: Due to its special motion trajectory and efficient screening method, the swinging screen can process a large amount of material in a short time.

3. Low noise: The support device of the swinging screen can effectively reduce the vibration and noise, and the noise generated in the working environment is relatively low. 

4. Versatility: By replacing screens with different mesh sizes and adjusting motion parameters, the swinging screen can adapt to the screening of materials of different particle sizes and properties. 

Specifications

What is the purpose of a swing vibrating screen?

Fine screening: used to separate fine particles or powdered materials, such as flour, powdered sugar, starch, medicinal powder, etc., to ensure uniform particle size of the materials.

Fragile material handling: suitable for screening fragile or fragile materials (such as granular food, crystalline materials), because its low-speed swinging motion will not destroy the material structure.

Viscous or moist material screening: processing materials with strong viscosity or high moisture content (such as chemical raw materials, Chinese medicine powder), because its movement can effectively prevent the screen from clogging.

High-precision classification: in scenarios where multi-layer classification is required, it is used to accurately classify materials according to different particle sizes, such as separating powders of different specifications in the pharmaceutical and cosmetic industries.

Special industry applications: widely used in food processing (such as seasoning, milk powder screening), pharmaceutical manufacturing (such as raw material screening), chemical production (such as pigment, coating screening) and other industries.

Recommended mesh number of the swing screen

1. Material with high screening accuracy (such as pharmaceutical powder, food additives) - 100-400 mesh is recommended.

2. Material with large particles that require efficient screening (such as sand and gravel, plastic particles) - 5-80 mesh is recommended.

3. Lightweight or easily agglomerated materials - a higher mesh number (200-400 mesh) can be selected, and the addition of ultrasonic or airflow auxiliary functions can be considered.

How to fix a swing vibrating screen?

Power-off operation: Be sure to cut off the power supply before repair to ensure safety.

Regular maintenance: Regularly check the screen, bearings, seals and other wearing parts and replace them in time.

Lubrication maintenance: Regularly add lubricating oil to the bearings and transmission parts to reduce wear.

Cleaning equipment: Clean the screen and the inside of the equipment after each use to prevent material accumulation.
