Removing and replacing the bowl
The bowl may be removed to empty, clean, maintenance, or other reasons. When replacing the bowl insure
that the two bosses on the underside of the bowl span one of the rubber isolators on which the bowl rests.
These bosses prevent the bowl from rotating during bowl operation. Insure that the bosses DO NOT rest on
any isolator. Insure that the bowl is held down using the large flat washer and wing nut provided.
Tips for getting the best service from your model 150 or 200 enhanced performance vibratory bowl
• Use the proper media to reach the result you expect. Burr King Manufacturing will assist you in selecting
the proper media, compound, and process. Use media that will obtain your desired finish without lodging
inside part cavities. Burr King Manufacturing's media is available in several grades, shapes, and material
types to be best for many part materials. Finishes can be obtained from a light matte to a chrome like
shine dependent on part material type and incoming part finish quality.
• Use the proper fluids (compounds) with your media of choice. Burr King recommends BKS-60 low suds
soap for non-ferrous materials, and AR-60 anti-rust soap for ferrous materials. Typically, these soaps are
mixed at 1 to 3 ounces per 1 gallon of clean water. Note that anti-rust soaps such as AR-60 will not
provide extended rust inhibition. If you require more than a few hours of rust inhibition, you should dip
your parts in a commercially available rust inhibitor solution.
• Maintain your media and equipment in a clean condition. If you use a re-circulating, filtration system
such as the Burr King FilterPAK
®
4000, it will greatly reduce the need to clean your bowl and media.
Without a filtration system, you will need to clean your bowl and media at regular intervals to remove
media sludge, and material fines that will accumulate inside the bowl.
• Do not allow your parts to rest in the bowl for extended periods. Doing so may result in stained,
oxidized, or etched parts.
• If your process uses ceramic or plastic media, clean and dry your parts immediately after withdrawing
them from the vibratory bowl. With dry media such as shell or cob cleaning may not be necessary.
• Establish a process time that allows the media and compounds of choice to process your parts to the
desired finish; control this process time from part load to part load in order to assure consistent load to
load results.
• Change your media when its size is reduced to a point that the media lodges in part cavities, if any. Also
change your media if its shape changes to a point where it will not reach desired surfaces.
• Pre-mix your fluids (compounds) to assure consistent mixture. Too much soap will delay results, too
little soap will reduce finish quality, and limit media life.
• Control the quality of the incoming part condition. Variation in lot to lot incoming part quality may cause
variation in the vibratory process output.

Occupational Noise Exposure
Burr King vibratory bowls produce levels of noise consistent with their intended purposes. The level
and spectral content of noise produced is dependent on the bowl size, the degree that the bowl is
maintained in proper operating condition, the abrasive/media and accessories used, the specific
application, use or not of the supplied lid, and the surrounding environment. Noise levels produced by
various Burr King vibratory bowls, as measured at the Burr King factory, range from 76 to 88
decibels. Product operators and persons in the immediate product vicinity should be protected from
excessive noise does levels as prescribed in OSHA regulation 29, part 1910.95 titled “Occupational
Noise Exposure”.
