A vibrating screen is a mechanical device used to separate materials based on size. It consists of a screen surface that vibrates to help move particles through openings, allowing smaller materials to pass while larger ones are retained. This equipment is commonly used in industries such as mining, construction, and recycling. The vibrating screen operates by using a motor to create vibrations, which helps to stratify the material on the screen. Different types of screens, such as linear screens and circular screens, are designed for specific applications, ensuring efficient separation and processing of materials.
