In each vibration cycle of the vibratory feeder, the plate's velocity is held positive (forward motion) for a longer time than it is held negative (backward motion). This type of asymmetric vibration combined with the non-linear nature of Coulomb friction causes the particles to accelerate along a straight line to a velocity called the ...

Vibrating Feeder Design
Vibratory feeders are basically applied to a control function to meter or control the flow of material from a hopper, bin, or stockpile, much the same as an orifice or valve control flow in a hydraulic system. In a similar sense, feeders can be utilized as fixed rate, such as an orifice, or adjustable rate, as a valve.
