WARNING: Failure to read and follow these installation instructions and safety
precautions could result in personal injury, equipment damage, shortened
service life or unsatisfactory equipment performance. All information in this
document is vital to the proper installation and operation of the equipment. It
is important that all personnel who will be coming in contact with this product
thoroughly read and understand this manual.
VIBCO turbine air vibrators are designed to keep noise pollution at a minimum. Compressed air
turns a specially designed turbine wheel that channels the air through the unit at frequencies well
above the human hearing range, making it virtually silent. Turbine vibrators average a whisper
quiet 72 dB. The BBS, BVS, MLT and MLTSS models should use a mufer to remove exhaust
air hiss. The VS model has a built-in mufer.
General Features
VIBCO turbine air vibrators operate in any position and are not adversely affected by dust, dirt
or wetness. Speed can be adjusted by varying the air supply pressure. The only moving part is
pre-lubricated for life and never needs oil, even for continuous duty.

Mounting Plate
For force up to 100 lbs. use a 1/4 in. thick plate, 100 to 500 lbs. use a 3/8 in. to 1/2 in. thick plate and over
500 lbs. use a 1/2 in. thick plate.(See Table).
Mounting Channel
Never place the vibrator directly onto the skin of the bin. It should be mounted to either a plate or a piece
of channel iron that has been welded to the bin. The proper mounting method is to use either 3 in. or 4
in. channel iron. This will help to stiffen the structure to be vibrated as well as spread the vibration over a
larger surface, increasing the overall efciency and diminishing the possibilities of fatigue cracks in the bin
material.
The length of the channel iron is determined by the thickness of the bin plate. For vibrators with a force up
to 500 lbs. and a bin plate under 3/16” the 4 in. channel iron should extend 18 to 36 inches on both sides
of the vibrator. For smaller vibrators with a force of up to 100 lbs. and a bin thickness of 3/16 in. to 1/4 in.
the length of the 3 in. channel iron should extend 3 to 4 inches on both sides of the vibrator. For vibrators
with a force between 100 and 500 lbs. and a bin thickness of 3/8 in. to 1/2 in. the length of the 3 in. or 4
in.channel iron should extend 6 to 8 inches on both sides of the vibrator. (See Table).
Warranty is void if vibrator is not properly installed. During installation follow and check off the
following steps and your vibrator should provide you with years of trouble-free service.
� Determine the length of the channel iron.
� Select thickness of vibrator mounting plate and method of mounting.
� STITCH weld mounting plate to channel iron.
� Determine where vibrator should be placed on the bin.
� STITCH weld channel iron to bin.
� Place vibrator on mounting plate. It is important that you check the
mounting plate for any warping. Secure vibrator rmly.
� Install safety chain or wire.
� Connecting pneumatics.
� Continuous vs. intermittent operation.

MOUNTING INSTRUCTIONS

Different Suggestions for Mounting the Channel
1. Mounting plate welded to legs of channel iron.
2. 3 in. or 4 in. channel iron with holes drilled thru and nuts welded on back side, or just holes
drilled thru.
3. Add mounting plate and drill and tap holes thru.
4. Notch the channel for access to mounting bolts.
5. Weld studs to back of channel.
Always stop welds 1 in. from ends to prevent cracks.
NOTE: for a list of alternate and special application brackets, see pg. 35 of the VIBCO General Catalog.
Placement
For coarse materials the vibrator should be mounted approximately 1/3 of the distance from
the discharge opening to the top of the sloped portion of the bin. For ne grain materials place
the vibrator approximately 1/4 of the same distance (see different mounting suggestions on the
following pages).
Welding Channel Iron To Bin
Where possible the mounting plate on the channel iron should be placed 1/3 to 1/4 of the distance
from the discharge opening to the top of the sloped portion of the bin. Stitch weld channel iron
in place, then weld intermittent welds 3 to 6” long with 3” between them along the entire length
of the channel. Stop weld a minimum of 1” from the ends, it is important that you do not weld
the ends of the channel iron. The heat concentration when welding the ends could cause the
beginning of fatigue cracks.
Installing Safety Chain
It is important to install a safety chain or wire in order to prevent the vibrator from falling and
potentially causing injury if it comes loose from its mount.

Welding Mounting Plate to Channel Iron
Weld the mounting plate to the middle of the channel iron. If the bin plate is 3/16 in. or less, weld
the mounting plate to the back of the channel iron (see gure 3 or 4). If the bin plate is over 3/16
in. weld the mounting plate to the legs of the channel iron (see gure 1). Drill and tap holes or
use studded plate (see gure 1).Make sure the mounting plate does not warp or distort. If this
occurs, straighten, replace it or shim up vibrator.

Heat Mounts for Insulated Bins Containing High Temperature Materials
When materials in the bin have a temperature over 150oF, it is advisable to use a “heat” mount to prevent excessive
heat from reaching the vibrator causing overload or bearing failure. Also ask for “high” temperature grease in
vibrator bearing. Consult VIBCO for vibrator size.
Use steel plate on inside and bolt to outside
mounting channel.
Mount steel plate on inside of bin so that the
vibrator sits 1/3 up bin side. Isolate the plate from
the concrete by using vibration shock absorbers.
Consult VIBCO for detailed drawings.

CHUTES
In order to successfully move material in a chute, the “angle of repose” of the material has to be
known. It can be found in most handbooks or can easily be measured by pouring a cup of the
material on a table. The angle between the table and the cone the material makes is the “angle
of repose”. To move the material in the chute, it should be inclined no less than 1/2 of the “angle
of repose” If this cannot be obtained, a feeder is necessary to move the material. (A) Chutes
up to 6 ft. are generally handled by one vibrator mounted approximately 1/3 from the discharge.
(B) On chutes over 6 ft. long, two vibrators are needed, one should be placed 18/-24” from the
discharge. The other approximately in the middle. Since chutes are very sensitive to vibration,
provision should be made to move the lower vibrator 6 inches in either direction. This could
mean the difference between moving the material or not moving it. (C) The direction of rotation
of the vibrator shaft should be in the direction of material ow. (D) Force (impact) needed on
vibrator is equal to weight of chute + vibrator + max material in chute. Chutes must have an
inclination of at least 10o for vibrators to be able to move the material. If inclination is less the
chute has to be made into a feeder. Contact VIBCO for selecting the proper size vibrator or ask
for the bulletin covering chutes.

Installation of the Vibrator
It is now time to put the VIBCO vibrator in place. Make sure that it is secured tightly. Retighten
the bolts after the rst 10 to 15 minutes of operation and check them periodically to maintain
proper tightness (gures 1 and 2).

Flow Valve
A simple ow control valve is recommended to allow “tuning” the vibrator to the desired force
necessary for solving your material ow problem. The air ow determines the force and
frequency of the vibrator. By throttling the air ow, you can “nd” the desired material discharge
rate. You should watch for and avoid speeds (frequency) at which the binwall and the vibrator
shake violently. An increase or decrease of air ow (assuming the mount is rigid) usually stops
the excessive movement and will smooth out the operation.
Quick Opening Valves
These are recommended between the air regulator and the vibrator so that the air enters the
vibrator at full starting force even at low regulator valve settings. The only requirement is that
you install the air regulator at least 12 inches away from the quick opening valve so that the
air pressure between the two valves will build up enough to yield the necessary starting force.
Solenoid (quick opening) valves are suggested for automatic operations. Automatic Timed
Cylcling is programmed with the timer usually directly connectd to the bin or hopper gate switch.
When the gate is opened the timed cycling system is activated.
Air Filter
It is recommended that you use an air lter in the line. Clean air will prolong the life of any
pneumatic vibrator. Dirty or moist air will harm the unit and impair it from operating at maximum
efciency and lowest air consumption.
Air Line To Vibrator
The hose to the inlet port of the vibrator should have the same or larger hose I.D. as the inlet
I.D. (pipe size) of the vibrator, so that the pressure loss from the compressor to the vibrator is
minimized.

To Obtain Maximum Performance
It is not necessary to operate the vibrator at its maximum capacity to obtain maximum performance.
Air regulators, timers, etc. should be used to tune the vibrator for optimum performance and
ensure longer life.
Continuous vs. Intermittent Operation
For bulk material bin applications, the vibrator should be used to reduce the material friction and
increase ow, not as a feeder. Once the friction of the particles is reduced, gravity ow takes
over and the vibrator should then be turned off for several reasons:
Economy. Most vibrators are run 60% to 80% longer than they should. Short bursts of vibration
are usually more effective than operating continuously. Experience has shown that for most
applications, short bursts of 10 to 30 seconds for every 1 to 5 minutes of discharge are more
effective and efcient.
Life of the Unit. The life of the vibrator will be determined by the length of operation and the
cleanliness of the air supply.
Guaranteed Success of the Application. The vibrator can only furnish material to the
discharge area. If more is furnished than conveyed, the remaining material will pack inside the
bin. We suggest the vibrators only run when the bin gates or doors are open, or when material
ow is needed.
Operating Instructions
VIBCO turbine vibrators function without maintenance. They require no lubrication in the air line.
It is advisable to put an air-cleaner in the line to prevent dust and dirt from going through the unit
and clogging the mufer. All models are easily repairable. Remove both nuts, press the shaft
out of the bearings and turbine. Use Andok C or Unirex N2 (by Exxon) or equal type of grease.
When reassembling be sure the turbine wheel is put back so that the incoming air will hit the
pocket of the tooth, not the back of the tooth.

PHONE ORDER: 1-800-633-0032 FAX: [phone]
WWW.VIBCO.COM [email protected]

If required, all models are easily repairable. The ball bearings can easily be changed by any maintenance mechanic
by removing the two end covers and pressing out the damaged bearings from the turbine wheel. Remove both nuts,
press the shaft out of the bearings and turbine. Note: Use Andok C or Unirex N2 (by Exxon) or equal type of grease.
When reassembling be sure the turbine wheel is put back so that the incoming air will hit the pocket of the tooth, not
the back of the tooth.
When new, the turbine vibrator might be slow in starting due to:
A. The bearings being packed with grease. Excess grease will be thrown out of the bearing after a short
operating time.
B. Temperature might be low causing the grease to be stiff. After a short operating time the grease will warm
and begin to loosen.
C. Bearing seals are stiff when new or cold. A brief run time will wear them in.
Sudden loss of vibration:
A. Loss of vibration could be caused by a cracked weld or a crack in the bin. Vibration will not travel through a
crack. Follow the instructions below on how to x the problem.
Troubleshooting
The improper welding of bin stiffeners, to which the vibrator is attached, often results in fatigue cracks in the bin.
This can be preventd by properly welding stiffeners to the bin side. A stiffener should be stitch welded to the bin leav-
ing 3 to 4 inches between welds. STOP WELDS 1 IN. FROM THE ENDS OF THE STIFFENER. This will prevent
fatigue cracks that occur due to crystalization of the material. This crystalization is caused by the heat concentration
that develops when the ends of the channel iron are welded. To stop the cracks, drill a hole at the end of each crack
and weld on a piece of angle iron as shown above. When welding on the angle iron STOP WELDS 1 IN. FROM
THE ENDS.

The Vibrator Won’t Start!
1. Check for dirt in the airline OR inlet opening
2. Check for dirt or debris clogging the exhaust mufer
3. Double check the size of your air line - is it large enough to give you the correct cubic feet per minute (CFM) and
correct air pressure (minimum required = 20 PSI)?
4. Did you mount the air regulator far enough away from the quick acting valve for the right amount of air pressure
to build up?
NOTE: Beraings may require a short “break-in” period to run at optimum VPM stated in the catalog
