High-frequency vibrating screen is usually operated at an inclined angle 0°-25°, up to 45°, and the operating frequency range is 1500-7200r/m. 7. Grizzly Screen. Grizzly screen is often used for pre-screening before coarse and medium crushing of materials. The mesh size is generally >50mm, but sometimes <25mm.
What are the components of the vibrating screen?
The steel frame should be constructed with bolted connections to avoid the cracking associated with weld failures. Due to the wet and corrosive environment of the dewatering, rubber springs should be used on the support legs to absorb the live frame vibrating loads, which will extend life and maintenance periods. High Frequency Screen
