Vibratory Feeder

A vibrating feeder or vibratory feeder is an industrial machine used to feed material to a process or machine. Vibratory feeders use both vibration and gravity to move material. They are mainly used to transport a large number of smaller objects.

A vibratory feeder is a machine used to feed bulk materials uniformly and continuously from a storage unit (like a hopper or silo) to the next process (conveyor, crusher, mixer, or packing machine).

It uses vibrations to move material forward in a controlled manner.

Working Principle :

Material is loaded onto the feeder tray

Vibrations are generated by the drive system

The tray moves in a small, rapid motion

This motion pushes material forward in a

controlled flow

The feed rate can be adjusted

by changing vibration intensity
