a device made with a screening surface vibrated mechanically at high speeds and used especially for screening ore, coal, or other fine dry materials.
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 above and directly connected to the screening surface. Its high-frequency characteristics differentiates it from a normal vibrating screen.
When linear vibrating screen works, the two motor reversely placed synchronously generate reverse force, which forces the screen body do the vertical motion. The materials on vibrating screen under the exciting force are periodically thrown forward to finish screening.
