Vibrating feeder is a kind of linear feeding equipment，consisting of the vibrating frame,vibrators,springs,electric motor,aircraft vibration and other components.  It can feed the crusher  uniformly in the sand or stone product line to protect the port of the crusher from being blocked.It is widely used in mining, building, silicate and chemical industries for crushing and screening.

Features

1. Flexible design
2. Heavy-duty,durable,all-welded body construction
3. Removable and adjustable grizzly bars
4. Variable speed by electric or electro/hydraulic drive
5. Enclosed oil-bath lubrication

Operating principle

There are two eccentric shafts rotating at high speed at the same time from opposite directions,thus the strong centrifugal force is formed.The component forces of centrifugal force along the vibrating direction will always overlap each other,then counteract with that of vertical force from vibrating direction,then exciting force along single direction is formed to drive the feeder vibrate along straight line.When materials are fed into the feeder,they may be thrown up and move like para curve,then fall down.The materials will move forward on the slope surface of the feeder.
