Four-layer vibrating screen

What is a four-layer vibrating screen?

Four-layer vibrating screen is a vibrating screening device with a four-layer screen structure. It is used for material classification, screening and filtering. It is mainly used for classification, screening and impurity removal of various granular and powdery materials. It is widely used in mining, metallurgy, chemical industry, building materials and other industries. It generates vibration through a vibration motor or exciter to make the material move on the screen surface, thereby achieving classification of materials of different particle sizes.

How does the four-layer vibrating screen work?

The vibration generated by the vibration motor makes the screen box resonate, so that the material on the screen surface jumps on the screen surface and moves forward. The apertures on the screen are different. During the movement of the material, the material larger than the screen aperture is retained on the screen surface, and the material smaller than the screen aperture passes through the screen and falls into the next layer, and so on, finally achieving material classification.

What are the different types of four-layer vibrating screen?

The structure of four-layer vibrating screen

Screen box: The screen box is the main body of the vibrating screen, usually made of stainless steel or carbon steel, with good corrosion resistance and wear resistance.

Screen mesh: The screen mesh is the core component of screening, usually made of stainless steel woven mesh or punching plate, and the aperture size is determined according to the screening requirements.

Vibration motor: Provides vibration power to make the screen box vibrate.

Vibration reduction device: Reduces the impact of vibration on the equipment and protects the equipment.

Support frame: Supports the entire screen machine to ensure its stable operation.

What are the advantages of a four-layer vibrating screen?

1. Solve the problem of irregular particle shape: For materials with irregular particle shapes, the four-layer vibrating screen can select the appropriate screen aperture and shape, and adjust the vibration parameters to achieve effective screening and grading.

2. Solve the adhesion problem of sticky materials: For sticky materials, the four-layer vibrating screen usually takes some measures to reduce adhesion, such as increasing the opening rate of the screen, using special anti-stick coatings, and adding vibration cleaning devices to ensure that the material can pass through the screen smoothly.

3. Deal with the clogging problem of high-humidity materials: High-humidity materials are prone to clogging and adhesion. The four-layer vibrating screen usually adopts heating, ventilation and drying to reduce the humidity of the material, or selects a special screen suitable for humidity materials to ensure the screening effect.

4. Deal with the problem of easy agglomeration of materials: Materials that are easy to agglomerate are prone to form agglomerates during the screening process. The four-layer vibrating screen can prevent material agglomeration and maintain the screening effect by reasonably designing the screen structure, adding a striking device or a vibration device, etc.
