Vibrating screen is a device commonly used for screening solid particles or liquids. It separates materials into particles of different sizes through vibration motion. It is widely used in mining, chemical industry, and other fields.

Vibrating screen working principle

Material input: Put the materials to be screened into the feed port of the vibrating screen.
Vibration drive: The vibrating screen generates periodic vibration force through a vibration motor or vibrator, which is transmitted to the screen surface.
Screening and separation: Materials produce rolling motion on the screen surface under the action of vibration force. Materials of different particle sizes are gradually separated according to their sizes. Finer particles pass through the sieve holes while larger particles are blocked on the screen surface.
Separation and collection: According to needs, materials of different particle sizes are collected separately through the discharge port at the bottom of the screen.

Vibrating screen structure
The main structure of the vibrating screen includes vibration motor or vibrator, screen body, screen surface, feed port, discharge port and other parts. Among them, the vibration motor or vibrator is responsible for generating vibration force, the screen body is the supporting structure of the vibrating screen, and the screen surface is the key component to achieve material screening.

Vibrating screen application areas

Mining: Used for screening and classifying mineral materials such as ore and coal.
Chemical industry: used for screening and dust removal of chemical raw materials and granular materials.
Environmental protection: used in environmental protection fields such as wastewater treatment and solid waste treatment.

Vibrating screen features
Vibrating screens usually consist of screen boxes, vibrators, screens and other components. Among them, the screen box is usually made of welded steel plates and has sufficient strength and rigidity to withstand the vibration force. The vibrator is connected to the screen box and transmits the vibration force to the entire screen box. The screen is the core component of the vibrating screen. Its aperture size determines the particle size of the screening. Commonly used screen materials include metal wire mesh, polymer screen, etc.
