Vibration feeders PWB are destined to feed dry grain or humid materia! with grain size adapted to the feeder size in cooperation with other devices such as: bins, tippers,conveyers, etc. The feeders comprise a self-suporting transport chute, inertial drive, coupling and suspension.
Chute inclination angle is 0-10° and adjustment is done by shortening or lengthening of ropes. Shafts of the inertial drives revolve with constant speed and input harmonically variable force with constant direction of reacting.
