Vibrating conveyor consists of a flat-bottomed metal trough, which transports material through controlled vibrations. With the help of vibrating conveyor bulk materials can be moved at any speed and volume. Vibrating conveyors tend to be the cleanest and most reliable conveyors, though they are limited in length and require fairly high maintenance. They are used extensively in food grade applications where sanitation, washdown, and low maintenance are essential. Vibrating conveyors are also suitable for harsh, very hot, dirty, or corrosive environments. Proper design of the support structure and foundations is important to ensure smooth operation and to reduce vibration into surrounding areas. Counter-balanced vibrating conveyor designs run the smoothest by eliminating nearly all-dynamic forces, thus reducing the need for expensive foundations.
