Worried about noise with your vibratory feeder bowl?
Vibratory bowls are naturally noisy. The electromagnetic coils that pull and release metal blocks beneath the bowl typically operate 60-120 times per second. The continuous movement causes the parts to vibrate against the bowl and other parts. The system becomes even louder based on the type of product being circulated. Depending on the part material, shape, and operating conditions, noise levels can become high enough to require hearing protection or additional noise reduction measures.
Fortunately, there are practical ways to reduce vibratory feeder noise while maintaining the performance of the feeding system.
Two common approaches to reducing vibratory feeder noise are applying noise-dampening bowl coatings and installing sound enclosures around the feeding equipment.
Coatings
There are several coating options that can be applied to vibratory bowls to reduce both noise and wear on parts. Polyurethane is a common and durable coating that works well with plastic parts and will reduce noise caused by parts vibrating against the bowl. For heavier metal parts, a Line-X coating provides a durable textured surface with more wear resistance than the typical polyurethane.
Coatings can be a practical, cost-effective option for reducing noise caused by parts contacting the feeder bowl. However, coating selection depends on the application, including part geometry, material, and any cleanliness or regulatory requirements.
Aluminum Sound Enclosures
Aluminum sound enclosures are another excellent option. Our sound enclosures provide an acoustic envelope to the feeding system by surrounding major components with aluminum panels lined with a sound-deadening foam. Enclosures can be customized to allow a hopper to supply the feeder and to provide operators with full access to all necessary areas of the machine.
Combining a bowl coating with a sound enclosure can provide additional noise reduction, particularly in applications with multiple feeder bowls or other noisy equipment nearby.
Need Help Reducing Vibratory Feeder Noise?
Noise reduction solutions depend on the parts being handled, the feeder’s configuration, and the surrounding production environment.
