Alum-A-Frame Enclosures

ENCLOSURES FOR GRINDERS

Sound Curtain Enclosure or Partition
Our sound curtain/sound blanket solution is a modular, flexible noise control option for your grinder noise control. Sound blankets such as our Model ABA-25 can provide up to 25 decibel reduction. Plant engineers, safety managers, maintenance workers have used ArtUSA Acousti Curtain technologies to assist them in providing a sound curtain solution to there particular application. Two sided, three sided or full sound enclosures have been used to lower unwanted grinder noise.
 

Features include • Flexibility • Sliding panels • Floor or ceiling mounting options • Clear windows for viewing • Access hatches, strip doors, sliding panels for material feed

Steel Sound Enclosure Cabinet or Room
ArtUSA manufacturers a high noise block with sound absorption qualities in our acoustic steel panel. Our 4" acoustical enclosure can lower noise levels up to 42 decibels. Our customers have realized high noise attenuation from our durable steel enclosure system.
Features include: • High noise reduction • Flexibility of modular removable panels • Doors, windows, hatches for material feed • Ventilation, lighting, and access all included

Our Grinder Enclosures are manufactured to the highest specifications. We can supply either a simple weatherproof enclosure or an acoustic enclosure. Weather louvers, acoustic louvers, splitter and baffles are provided to suppress the noise where required.

Special features

Many special features are available depending upon the application.

Hinged or lift off doors with single or double seals - Single or double glazed windows - Louvers to minimize water entry and maximize air flow through the enclosure - Mesh openings to stop vermin and vandalism -   Ventilation - by means of an auxiliary fan - Inlet filters - replaceable and panel types - Vibration isolation - rubber mounted - Internal partitions - from sheet steel - Roof reinforcing - for larger enclosures

We can also design for - Ventilation and cooling - Access points - Equipment vibration - Environmental issues

Construction

Acoustic enclosures will be as varied as the customer's requirements (or one's imagination).  The enclosure outer walls generally consist of 16 gauge thickness of galvanized mild steel sheeting, and are internally lined to meet your requirements. The lining material can vary from rock wool covered with perforated metal to foams and composites.

We can build the acoustic enclosure around your machine after it has been delivered to our factory, or design and build using your detailed drawings.

The design of the acoustic enclosure is capable of variation to many machine noise problems. Requirements can range from a small noise reduction, in which a minimal solution will be adequate, ie. an enclosure which may not fully enclose the machine, can achieve 5-10 dB(A) noise reduction. More elaborate enclosures can achieve a noise reduction of greater than 30dB(A), and can consist of one enclosure inside another.

Painting of the equipment can be included in our manufacturing, and will vary from finishing with machine enamel to two-pack epoxy, powder coating or other options.

Drop over acoustical enclosures can be used when it is necessary to suppress noise pollution from machinery either fixed or mobile. Legally employers must protect their employees from continuous high noise levels above 85dB(A).Equipment such as presses, foundry shake-out machines, nail making machines, and granulators require an inlet and outlet for entry and exit of the product. These openings need attenuation to minimise noise emission. Fans emitting considerable noise through the casing will also need to be enclosed and therefore penetrations will need to be provided for the air inlet and outlet. A small ventilation fan may be needed to remove the electric motor heat.
