There are several types of feeders all suited for different applications. They can be classified according to their working principle.
Apron and chain feeders for example transport the material with the help of pans or a transport chain, which move along the feeder tray. Belt feeders, as the name indicates, use a rubber belt to transport the material. Vibrating feeders use a totally different working principle, as there is no transport media as such. Here, the material is transported by a linear vibration, mostly generated by linear exciters.
