Vibrations to separate materials based on size, shape, or density. They work by feeding material onto a screen surface with openings, where smaller particles pass through while larger ones are retained. The vibration is generated by a mechanism with an eccentric shaft or vibrating motor, which creates a dynamic motion that facilitates the separation. The vibrating motion lifts and moves the material across the screen surface. Some vibrating screens have multiple decks with different sized openings, allowing for multiple separation stages in a single pass.
