"A vibrating motor imparts both linear and vertical motion to a deck or screen surface, causing particles to move across the screen. As these particles encounter the openings in the screen mesh, smaller particles pass through, while larger ones are retained." The applications of vibrating screens are diverse, spanning various industries.
