SAFETY INSTRUCTIONSWARNING: Failure to read and follow these installation instructions and safetyprecautions could result in personal injury, equipment damage, shortenedservice life or unsatisfactory equipment performance. All information in thisdocument is vital to the proper installation and operation of the equipment. Itis important that all personnel who will be coming in contact with this productthoroughly read and understand this manual.HOW IT WORKSVIBCO turbine air vibrators are designed to keep noise pollution at a minimum. Compressed airturns a specially designed turbine wheel that channels the air through the unit at frequencies wellabove the human hearing range, making it virtually silent. Turbine vibrators average a whisperquiet 72 dB. The BBS, BVS, MLT and MLTSS models should use a muffler to remove exhaustair hiss. The VS model has a built-in muffler.General FeaturesVIBCO turbine air vibrators operate in any position and are not adversely affected by dust, dirtor wetness. Speed can be adjusted by varying the air supply pressure. The only moving part ispre-lubricated for life and never needs oil, even for continuous duty.NOTE:On BVS, BBS,MLT & MHImodels, the smallerINNER port is the airinlet and the largerINNER port is theexhaust.Optional Features For MLT Models Metric Threads Special Coatings: High gloss dairy white industrial enamel Anodized or unpainted aluminumPHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM2

Mounting Instructions ChecklistWarranty is void if vibrator is not properly installed. During installation follow and check off thefollowing 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 themounting plate for any warping. Secure vibrator firmly. Install safety chain or wire. Connecting pneumatics. Continuous vs. intermittent operation. FILL OUT WARRANTY CARD!!!MOUNTING INSTRUCTIONSIf you have any questions consult the Mounting Instruction section of this manual or callVIBCO’s Technical Support at (800) 633-0032.Mounting PlateFor 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 over500 lbs. use a 1/2 in. thick plate.(See Table).CORRECT MOUNTING PLATESLBS. OF FORCEup to 100 lbs.100 to 500 lbs.over 500 lbs.PLATE THICKNESS1/4" plate3/8" to 1/2" plate1/2" plateMounting ChannelNever place the vibrator directly onto the skin of the bin. It should be mounted to either a plate or a pieceof channel iron that has been welded to the bin. The proper mounting method is to use either 3 in. or 4in. channel iron. This will help to stiffen the structure to be vibrated as well as spread the vibration over alarger surface, increasing the overall efficiency and diminishing the possibilities of fatigue cracks in the binmaterial.The length of the channel iron is determined by the thickness of the bin plate. For vibrators with a force upto 500 lbs. and a bin plate under 3/16” the 4 in. channel iron should extend 18 to 36 inches on both sidesof 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 vibratorswith 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 4in.channel iron should extend 6 to 8 inches on both sides of the vibrator.

Welding Mounting Plate to Channel IronWeld the mounting plate to the middle of the channel iron. If the bin plate is 3/16 in. or less, weldthe mounting plate to the back of the channel iron (see figure 3 or 4). If the bin plate is over 3/16in. weld the mounting plate to the legs of the channel iron (see figure 1). Drill and tap holes oruse studded plate (see figure 1).Make sure the mounting plate does not warp or distort. If thisoccurs, straighten, replace it or shim up vibrator.Different Suggestions for Mounting the Channel1. 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 holesdrilled 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.123a3b45NOTE: for a list of alternate and special application brackets, see pg. 35 of the VIBCO General Catalog.PlacementFor coarse materials the vibrator should be mounted approximately 1/3 of the distance fromthe discharge opening to the top of the sloped portion of the bin. For fine grain materials placethe vibrator approximately 1/4 of the same distance (see different mounting suggestions on thefollowing pages).Welding Channel Iron To BinWhere possible the mounting plate on the channel iron should be placed 1/3 to 1/4 of the distancefrom the discharge opening to the top of the sloped portion of the bin. Stitch weld channel ironin place, then weld intermittent welds 3 to 6” long with 3” between them along the entire lengthof the channel. Stop weld a minimum of 1” from the ends, it is important that you do not weldthe ends of the channel iron. The heat concentration when welding the ends could cause thebeginning of fatigue cracks.Installing Safety ChainIt is important to install a safety chain or wire in order to prevent the vibrator from falling andpotentially causing injury if it comes loose from its mount.PHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM4

Heat Mounts for Insulated Bins Containing High Temperature MaterialsWhen materials in the bin have a temperature over 150oF, it is advisable to use a “heat” mount to prevent excessiveheat from reaching the vibrator causing overload or bearing failure. Also ask for “high” temperature grease invibrator bearing. Consult VIBCO for vibrator size.Mount steel plate on inside of bin so that thevibrator sits 1/3 up bin side. Isolate the plate fromthe concrete by using vibration shock absorbers.Consult VIBCO for detailed drawings.7Use steel plate on inside and bolt to outsidemounting channel.PHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM

CHUTESIn order to successfully move material in a chute, the “angle of repose” of the material has to beknown. It can be found in most handbooks or can easily be measured by pouring a cup of thematerial on a table. The angle between the table and the cone the material makes is the “angleof repose”. To move the material in the chute, it should be inclined no less than 1/2 of the “angleof repose” If this cannot be obtained, a feeder is necessary to move the material. (A) Chutesup 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 thedischarge. 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 couldmean the difference between moving the material or not moving it. (C) The direction of rotationof the vibrator shaft should be in the direction of material flow. (D) Force (impact) needed onvibrator is equal to weight of chute vibrator max material in chute. Chutes must have aninclination of at least 10o for vibrators to be able to move the material. If inclination is less thechute has to be made into a feeder. Contact VIBCO for selecting the proper size vibrator or askfor the bulletin covering chutes.PHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM8

VIBRATOR INSTALLATIONInstallation of the VibratorIt is now time to put the VIBCO vibrator in place. Make sure that it is secured tightly. Retightenthe bolts after the first 10 to 15 minutes of operation and check them periodically to maintainproper tightness (figures 1 and 2).Damage to the bin and the vibrator can occur if not mounted securely.FIGURE 1 Remember:Check thosebolts!

Air Line To VibratorThe hose to the inlet port of the vibrator should have the same or larger hose I.D. as the inletI.D. (pipe size) of the vibrator, so that the pressure loss from the compressor to the vibrator isminimized.TO DETERMINE CORRECT AIR HOSE SIZE**TURBINE MODELNUMBERMIN AIRHOSE DIAMIN FR*THREAD DIACFM100 - 130160 - 250320 - 380440 - 5105701/8"1/4"3/8"1/2"3/4"1/4"1/4"3/8"1/2"3/4"4-67 - 1010 - 1818 - 2121 - 30* F filter R regulator** these specs for installation of single unit;for multiple units, adjust to maintain CFMFlow ValveA simple flow control valve is recommended to allow “tuning” the vibrator to the desired forcenecessary for solving your material flow problem. The air flow determines the force andfrequency of the vibrator. By throttling the air flow, you can “find” the desired material dischargerate. You should watch for and avoid speeds (frequency) at which the binwall and the vibratorshake violently. An increase or decrease of air flow (assuming the mount is rigid) usually stopsthe excessive movement and will smooth out the operation.Quick Opening ValvesThese are recommended between the air regulator and the vibrator so that the air enters thevibrator at full starting force even at low regulator valve settings. The only requirement is thatyou install the air regulator at least 12 inches away from the quick opening valve so that theair 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 TimedCylcling 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 lveTo GateTo ControlSwitchTimerDO NOT LUBRICATE!Air FilterIt is recommended that you use an air filter in the line. Clean air will prolong the life of anypneumatic vibrator. Dirty or moist air will harm the unit and impair it from operating at maximumefficiency and lowest air consumption.PHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM10

Maximum Air PressureThe operating pressure of the vibrator should not exceed 80 psi and should be no lower than60 psi unless specially contructed by VIBCO. Max air pressure for BVS-60, VS, BBS and FBS100 should be 60 psi (Figure 3).Maximum TemperatureThe operating temperature of the vibrator should not exceed 200oF (93oC).

Operating InstructionsTo Obtain Maximum PerformanceIt 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 andensure longer life.Continuous vs. Intermittent OperationFor bulk material bin applications, the vibrator should be used to reduce the material friction andincrease flow, not as a feeder. Once the friction of the particles is reduced, gravity flow takesover 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 vibrationare usually more effective than operating continuously. Experience has shown that for mostapplications, short bursts of 10 to 30 seconds for every 1 to 5 minutes of discharge are moreeffective and efficient.Life of the Unit. The life of the vibrator will be determined by the length of operation and thecleanliness of the air supply.Guaranteed Success of the Application. The vibrator can only furnish material to thedischarge area. If more is furnished than conveyed, the remaining material will pack inside thebin. We suggest the vibrators only run when the bin gates or doors are open, or when materialflow is needed.MaintenanceVIBCO 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 unitand clogging the muffler. All models are easily repairable. Remove both nuts, press the shaftout 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 thepocket of the tooth, not the back of the tooth.PHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM12

TroubleshootingThe Vibrator Won’t Start!1. Check for dirt in the airline OR inlet opening2. Check for dirt or debris clogging the exhaust muffler3. Double check the size of your air line - is it large enough to give you the correct cubic feet per minute (CFM) andcorrect 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 pressureto build up?NOTE: Beraings may require a short “break-in” period to run at optimum VPM stated in the catalogIf required, all models are easily repairable. The ball bearings can easily be changed by any maintenance mechanicby 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, notthe 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 shortoperating time.B. Temperature might be low causing the grease to be stiff. After a short operating time the grease will warmand 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 acrack. Follow the instructions below on how to fix the problem.If cracks have developed, drill holes at the ends of thecracks and weld on angle iron as shownStop welds at least 1 in.from endsMounting platefor vibrator3 or 4 in.channelDo not weld 1 in. fromend of stiffenerThe 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 leaving 3 to 4 inches between welds. STOP WELDS 1 IN. FROM THE ENDS OF THE STIFFENER. This will preventfatigue cracks that occur due to crystalization of the material. This crystalization is caused by the heat concentrationthat develops when the ends of the channel iron are welded. To stop the cracks, drill a hole at the end of each crackand weld on a piece of angle iron as shown above. When welding on the angle iron STOP WELDS 1 IN. FROMTHE ENDS.13PHONE ORDER: 1-800-633-0032FAX: 1-401-539-2584WWW.VIBCO.COMVIBRATORS@VIBCO.COM
