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 and shape, the noise level of a feeder system can quickly become harmful to unprotected ears.
Fortunately, there are options for helping to decrease the noise, keep your employees safe, and maintain the efficiency of the feeding system.
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 are an economical and simple solution for noise reduction and work well in most applications. However, there are select applications where coatings should not be used such as parts with sharp edges or medical or pharmaceutical products.
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.
Using a coating in conjunction with a sound enclosure can drastically reduce noise in excessively loud situations such as if you’re operating more than one feeder bowl or have other pieces of noisy equipment.
