A company wanted to reduce noise from its vibratory bowl feeders without enclosing them. The metal components inside the vibrating bowl feeders kept jamming and this required frequent operator access to clear the blockage and re-start the flow of components. An acoustic enclosure would have restricted access, slowing down the operator. Fitting acoustic enclosures would also have made it more difficult for operators to spot blockages by preventing them seeing inside the bowls.
We provided an engineering noise control solution that involved installing minor modifications inside the vibrating bowls. So the vibratory bowls were not covered by an enclosure, hood or cover. This meant that access and visibility were not impaired, as would have occurred with an enclosure. One of the vibratory bowl feeders is shown above.
Our solution achieved a large noise reduction of 12 dBA.
We also identified the root cause of the blockages and made modifications that prevented blockages occurring in future. So as well as providing a high noise reduction, our solution also improved productivity because it freed operators to do other things instead of spending lots of time clearing blockages.
Furthermore, the cost of our engineering solution was much lower than had the company selected acoustic enclosures, hoods or covers - the types of noise control equipment normally used for a vibrating bowl feeder or vibratory feeder / conveyor.
Our engineering noise solutions can be applied to vibratory deburrers and linear vibrating feeders / conveyors as well as bowl feeders, while providing the same benefits of no access or visibility restrictions, low cost and high noise reduction.
