High-frequency vibrating screens - Wikipedia

High-frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200 μm in size, and are applicable to both perfectly wetted and dried feed. The frequency of the screen is mainly controlled by an electromagnetic vibrator which is mounted ...

Operational Theory. The Prater Vibratory Screener utilizes a vibrating deck that is attached to one or more screening elements. Each of the screens is used to segregate and capture a specific size fraction of the aggregate particle mixture. Screening efficiency is much greater when a vibratory enhancement is added to the sizing process.

Vibrating Screen Working Principle

What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.
