Vibratory feeders are used to withdraw or receive material and transport it uniformly for further processing.
Common applications include:
- Removing material from storage hoppers or silos.
- Receive dumped loads from front end loaders or cranes.
- Spread material evenly to fulfill process requirements.
- Controlling output and distribution of material for receing equipment.
Build materials for vibratory feeders are generally mild steel. Stainless steel troughs are also used in applications where corrosion resistance or food grade finishes are required.
Feeders can be tapered down to fit narrow belts or other interfacing equipment. They can also taper out to spread out material and lower material depths if required. Curved troughs can be designed to eliminate the need for chutes that direct material 90 degrees. Alternatively, hopper style designs where the trough body tapers out vertically helps prevents material from spilling out when loaded.
Ideally, sub resonant drive systems are used on vibratory feeders. This is to allow robust constructions yet have a fine feed rate control. Direct drive feeders are an alternative that can be supplied when simplicity is preferred.
Operating angles of vibratory feeders affect material speeds and behaviour. Horizontal installations are standard and provide good feed rate control. If material speed needs to be higher, feeders are installed on inclination angles.
Lining the troughs of feeders is done to either increase life or assist in material flow. Head wearing steel or ceramic liners are used to protect trough bodies from material wear. Plastic based liners are generally used to reduce the risk of sticky material.
When withdrawing material from stored mediums such as bins or silos, the interfacing between the storage outlet and the feeder is critical to proper performance. Vibroflow will assist in the design of the interfacing system with the supply of a feeder.
With electronic control systems, feed rates on sub resonant feeders can be controlled with precision. The amplitude on direct drive feeders can be adjusted by changing the settings on the motors out of balance weights.
Vibroflow offers a wide selection of vibratory feeder designs to facilitate specific requirements. We can assist in the selection of the appropriate feeding technology to satisfy clients' requirements.
