How to choose and use vibratory feeders and conveyors

Vibrating, again by definition, means "to move back and forth rapidly." The equipment and process solutions described in this guide all use this rapid "back and forth" motion to move or convey product. On a vibratory feeder, material is "thrown" up and forward so that it drops to the surface at a point further down the tray.
