How Do Vibratory Feeders Work?

At Gough Engineering, we provide bespoke vibratory feeders. Vibratory feeders are used to achieve a controlled and even flow of materials through a section of a production line. Vibratory feeders are relatively simple to operate and maintain.

But how do vibratory feeders work?

The feeders use vibrations to convey materials along a production line or into a process point. The drives of the feeders are angled to generate a rapid series of forward hops that individually are imperceptible to the naked eye, but combine to create a continuous product flow that is even able to move product up a shallow incline. The specifics of how the feed is generated depend on the system chosen, which is usually determined by the application. The types of feeder include:

• Heavy duty twin motor feeders
• High frequency electromagnetic feeders

Heavy duty feeders use a twin motor with coil spring suspension. The feeding action is achieved due to the vibration of the feeder tray, generated by the two sets of out-of-balance weights spinning at over 1,000 rpm. The motors are angled to send the waves of momentum through the product to create the forward hops.

High frequency electromagnetic feeders generate vibrations using an electromagnetic coil and magnet. The electromagnetic coil is attached to a base and the magnet is attached to the feeder tray. The electromagnetic coil turns on and off at a high frequency attracting the magnet when it is on, which then springs away on the flat suspension springs when it is off, creating the hops to move the product.

Vibratory feeders at Gough Engineering

At Gough Engineering, vibratory feeders are custom manufactured from proven designs. We manufacture both high frequency electromagnetic and heavy duty twin-motor vibratory feeders.

The electromagnetic feeders give greater control over the product, providing either a continuous feed, or a feed that can be regularly stopped and started for a more measured throughput. These feeders are generally used for applications that demand careful handling, such as in food processing environments. The twin-motor feeders are designed to give a continuous, even flow of product. These feeders are generally used for more heavy duty applications, where high throughputs are required over gentle handling.

All feeders are designed to be simple to operate, and once set up, require virtually no maintenance. Should you require any more information about our vibratory feeders, do not hesitate to contact us.
