Vibrating feeder is an instrument that uses vibration to “feed” material to a process or machine. Vibratory feeders use both vibration and gravity to move material. Gravity is used to determine the direction, either down, or down and to a side, and then vibration is used to move the material. They are mainly used to transport a large number of smaller objects.

Many varieties of vibratory feeders operate mechanically, either through the interaction of gears or other mechanical means.

Electromagnetic vibratory feeders are particularly suited to applications where precise control over vibration is needed. This can be achieved with electromagnetic feeders because their drive mechanisms can be controlled and stopped more easily than some mechanical alternatives. For these reasons, electromagnetic vibratory feeders are often favorable alternatives to other feeders with different drive mechanisms. Vibrating grizzly feeder(Feed grizzly) used in extraction and conveyance of materials of very large size from storage bins and hoppers, and are conveyed to downstream crushers, while screening the materials. Vibrating grizzly feeder is used in feeding calcareous, calcium containing material with a size up to 1,000mm at 600m3 per hour also it is used for the separation of fines from primary feed or secondary feed to the crushing plant and is meant for heavy duty applications.

vibrating feeders can also have magnetic drives, which means that their motion is controlled by the interaction of magnets within the drive. Electromagnetic vibratory feeders are characterized by a number of favorable factors, including high conveying speed and quick stopping, efficiency in terms of consumption of electricity and many other favorable qualities. Despite the differences in operation, electromagnetic vibratory feeders are capable of the same kinds of material handling tasks as other vibratory feeder varieties. Like other kinds of vibratory feeders, electromagnetic vibratory feeders are capable of moving objects within an industrial facility. They can be used to transport ingredients to destinations within manufacturing processes, they can be used to transport finished products to packaging and they can be used for all manner of other small objects handling within industrial facilities.

Some of the principle advantages of vibratory feeders over other types of bulk feeding devices are the opportunity for utilizing full sized hopper openings to reduce bridging and assure free flow of material by vibrating material in the hopper throat and eliminating the requirement for bin vibrators. The vibratory feeder pan eliminates, in most cases, requirements for rack and pinion gates and other shut-off devices above feeders since the feeder pan functions as a shut-off plate. The design of the unit permits replacement of the drive mechanism without removing feeder trough. There is a reduction in headroom requirements and considerable savings in pit or tunnel construction. Eliminating gates also promotes the free unobstructed flow of material. The ability to vary the feed control from absolute zero to maximum in response to instrumentation signals meets the design requirements for automated blending and reclaim systems. Scrapers and spillage are eliminated and vibrating feeders can be easily designed for dust-tight applications.
