How Do Vibratory Bowl Feeders Work

Vibratory bowl feeders are typically found in production lines for various manufacturing industries. It’s a piece of standard equipment for handling and sorting bulk products for processing machinery and various forms of packaging lines. Part of the reason why it hasn’t changed in design over the years is its robust design that doesn’t require a line operator.

Recognizing vibratory bowl feeder’s purpose in different industries 

Vibratory bowl feeders are useful to many industries, from the pharmaceutical to electronics sectors. Its function of presenting parts one by one to an assembly machine makes it applicable to serve various purposes, like delivering machinery components or arranging food packaging.

After proper alignment from the bowl, the separate parts are bundled into batches in their respective categories. Bowl feeders can process materials up to 10 meters per minute, allowing a seamless and continuous supply to the processing line. Manufacturers that handle sensitive material like chemicals and food products require the feeding bowl to be made from stainless steel to meet standard cleanroom conditions.

Understanding a vibratory bowl feeder’s parts

Vibratory bowl feeders are for aligning proper feeding within a production line. A series of coordinated vibrations from electromagnets produces a mechanical reaction that forwards the parts feeding process. A mounted bowl receives support from 4 to 5 leaf springs, restraining movement so that the bowl can only move vertically. A fixed magnetic coil under the bowl feeder magnetizes it to produce electromagnetic vibrations.

There are generally 1 to 6 electromagnets under the feeder base, which transform magnetic vibrations into mechanical reactions. Through this movement, the bowl passes the force to the corresponding bowl conveying tracks to feed into the production line. The electromagnets create 100 cycles of vibrating frequencies that allow the materials on the bowl to slide or hop along its tracks to simulate movement.

A bowl feeder usually connects into a system that has a bulk hopper or bulk handling storage device. These are then integrated into an outfeed track and control system. Like any conveying equipment, it’s necessary to fit it with a bulk material’s shape, size, and weight to ensure that it will have proper traction for orienting and feeding.

An inline track is necessary to accommodate the bowl feeder’s accumulation of oriented materials to feed directly into the processing line. In turn, the bulk hopper holds a defined amount of materials to dose the bowl feeder, depending on the control system’s settings. This allows the operator a short window to check between fill up. Vibrating conveyor manufacturers may apply a coating to the entire system to accommodate oily and sticky material.

Valuing the advantages of a vibratory bowl feeder

The advantage of a vibratory bowl feeder’s unique conveying function allows for smooth and consistent movement. It reduces energy consumption by 40% since its simulation of movement is through electromagnetism. Additionally, the tooling in the bowl can conveniently rearrange your material to the right orientation. It can also push out misaligned parts back to the bowl’s center for reorientation.


Numerous conveying products in the market boast distinct features that fit particular industries’ product handling and packaging. Understanding the different conveying equipment options available will give you better insight into what products will work best for your business. If you want to focus on energy consumption while optimizing your production line, vibratory bowl feeders can be the solution you’re looking for.
