It usually consists of a screen body, a screen surface, four groups of vibration isolation system, and an excitation system (i.e., a unilateral-driven system and two box-type exciters). The screen body is a composite structure composed of two side panels, an excitation beam, several bearing beams and stiffeners and so forth.
As the material flows onto the screen, the vibration separates particles by size. Smaller particles pass through the mesh openings while larger particles are retained on the screen surface. The vibrating action is essential for several reasons. First, it creates momentum for material movement down the screen. ... The operating temperature can ...
