Screening machinery is the mechanical machinery that uses rotating, vibrating, reciprocating and shaking to screen the raw materials and primary materials into several grade according to the size of materials or remove the water and impurities for next step processing.
There are many kinds of screening machinery and they can be divided into different types according to their structures and movement futures:
1. Fixed screen: it includes fixed grizzly screen, fixed grizzly bar, cantilever grizzly bar and sieve bend.
2. Barrel screen: cylinder screen, cone screen and pyramid screen etc.
3. Plane shaking screen
4. Vibrating screen: it includes mechanical drive and electrical drive. The eccentric vibrating screen, inertia vibrating screen, self-centered vibrating screen, linear vibrating screen and resonance screen belong to mechanical drive. Electric vibrating screen is electrical drive.
