Useful Information & FAQThe following are a collection of helpful tips and suggestions thatmay provide youwith someassistance while using ourADMIX products.

Shaft Straightness

Shafts can only be straightened once they are installed in the mixer. Shaft straightness MUST bechecked each time newbearings or a new shaft is installed.

See "Check Shaft Straightness" on page 21 for additional instructions.

Water / Condensation Awareness

When amixer is operated and then shut down formore than 2 hours, it will cool to ambienttemperature. This temperature swingmay cause condensation to form. If the entire mixer is notcompletely sealed,moisture could be drawn into the unit. Anymoisture inside the bearing frameswill lead to premature bearing failure. ADMIX includes a vent on the bearing frames toaccommodate this occurrence. If the vent becomes damaged replace immediately. SeeMaintenance for additional instructions.If the motor has been replaced, are all of the weep holes in the motor plugged? If not be sure tocorrect. On top entry / batchmixers, make sure that the O-ring is installed between the motor andthe bearing frame.

Rotation

If equipped,make sure that the foils are installed on the shaft so that they are pumping down. SeeIMPELLERS for additional instructions. In some rare cases, yourmixermay be designed to be “uppumping”.DIRECTDRIVE: Rotation is CLOCKWISE when viewed from the top (fan end) of the motor.

Useful Info and Tips

If using a support thatmay bemade of carbon steel, take precautions to avoid contact between itand the Shaft, Mixer Headassembly or Bearing frame. The mild steel could contaminate thestainless steel and possibly induce corrosion.

CAUTION:NEVER FORCE PARTS TOGETHER.Most mating parts are designed to easily slidetogether. If you experience difficulty, check individual parts for dirt, dents, burrs, orgallingmarks.

Uncrating & Inspection

Inspection

After uncrating yourmixer, check for shipping damage and report any damage immediately to thecarrier and to ADMIX. Please make sure that all parts are accounted for.The mixer is normally shippedpre-assembled. Some of ourmodels are shippedwith their shaftsremoved. These items may also be crated separately. Do not remove protective wrappings if themixer is to be stored before it is placed in operation. Store the mixer in a clean, dry location.If yourmixer is to be stored for an extendedperiod:

Rotate its Shaft every three months.

Protect it from extreme temperature conditions.

Protect it frommoisture.

Isolate it from any vibration.

Impropermotor storage will result in seriously reduced reliability and failure. An electricmotor thatdoes not experience regular usage while being exposed to normally humid atmospheric conditionsis likely to develop rust in the bearings or rust particles from surrounding surfaces may contaminatethe bearings. The electrical insulationmay absorb an excess amount of moisture leading to themotorwinding failure.

Warning Moving Crated Equipment:


Transportation andmoving should only be performedby trained personnel.

Lifting of equipmentmust be done using hoists that are designed for the total weight of the equip-ment. Ensure that the area below the raised equipment is clear of people.Consider the center of gravity of the crated equipment when lifting.

Remove any packagingmaterials, support bracing and protective films or caps.

Observe local safety practices and procedures.

Installation Safety Precautions

Always observe local safety programs and procedures.

Always assure your lifting and supporting equipment is suitable for requiredweight.

Never lift or carry the mixing unit by its shaft.

Always observe local LockOut TagOut procedures.

Installation

DANGER:Immediate hazards whichWILL result in severe personal injury or death.Interlocks should be installed on all personnel access stations to prevent injury duringinternal tankmaintenance.

CAUTION:DO NOT LIFTORCARRY FROMTHE SHAFT as this could cause the shaft to bend andmaylead to excessive vibration or damage. Lift the mixing unit from the BEARING FRAME orGEARBOX/MOTOR ASSEMBLY ONLY.

CAUTION:ADMIXmixers MUST BE FIXED SECURELY TO AMOUNTING PLATE OR FLANGE, and cannotbe suspended on hooks or straps or any other non-fixed device.

Moving &Mounting the Mixer

The mixermust be installedONLY vertical or slightly inclined (0-10 degrees) for proper operation infixedmount applications.Remove the mixer from its packaging and clean off any protective coatings. Align the holes of theMixerMount with the holes of the Bearing/Gearbox frame. Secure the mixerwith the Hex HeadBolts, LockWashers, and Hex Nuts. Frequently inspect the mounting hardware to insure they areproperly tightened. Impropermounting could lead to personal injury.

"Bolt Torque Table: Standard Bolts" on page 48

Note: If using a support thatmay bemade of carbon steel, take precautions to avoid contactbetween it and the Shaft, Mixer Headassembly or Bearing frame. The mild steel couldcontaminate the stainless steel and possibly induce corrosion.

Utilities RequiredSee Customer Drawing and Mixer Data Sheet for electrical motor requirements.

Wire the Motor

DANGER:Immediate hazards whichWILL result in severe personalinjury or death.Interlocks should be installed on all personnel accessstations to prevent injury during internal tankmaintenance.

CAUTION:Use proper care and follow local codes when performingwork on any electrical device.

Motormust be installed in accordance with all applicable federal,state and local electrical codes.Connect the motor via an overload protection device and checkfor proper rotation. Each ADMIX product is suppliedwith a rotationalarrow for ease of reference.Mixer Shaft rotationmust be CLOCKWISE, when seen from abovethe mixer.Use proper care and follow local codes when performingwork onany electrical device. Connect the electricpower to the Motor.

Motor Information

Lock Out Critical Speed

All mixers have what is called critical speed. This is a harmonic that becomes obvious when themixer is run in that speed range. Typically, it will be seen in the form of a vibration orwobble in theshaft system.Many times this becomes apparent when a variable frequency drive (VFD) is addedand the mixer speed is changed to optimize the process. Before varying the speed of yourmixerrefer to the Mixer Data Sheet (See MDS in YourMixer) for the critical speed and the recommendedlockout range. Typically, youwould lockout 20%on either side of the critical speed.

Mixer Overload

As products and formulas change, viscosity and solids may change, too, as will the load on themotor. As an example, if specific gravity changes from 1.0 (8.34#/gal) to 1.3 (10.84#/gal), powerdrawon the mixer (or a pump)also changes by that ratio. A 2 HPmixer that drew 1.7 HP at 1.0 SGnowdraws 1.7 x 1.3 = 2 HP and is nowoverloaded.

Wash-downmotor Installation

If a wash-down dutymotor is required for your tough environment, consider that evenwash-downdutymotors may fail if the correct weep holes are not plugged. The intent of aweep hole in anelectricwash-down dutymotor is to allowwater to escape. If the correct weep holes are not open,it could allowwater to pool in the bearings and cause premature failure.

Check Shaft StraightnessOnAdmixmixers, shaft straightness is critical to bearing life. Eachmixer has its shaft straightened to aspecific TIR at the factory.

IMPELLERS / FOILS

Maintenance Checklist

BEFORE STARTING THE MIXER, CHECK THE FOLLOWING:

Check the rotation of the mixer shaft by jogging the mixer for 1-2 seconds. Clockwise rotation whenviewed from above is correct. We recommend rotation be checked prior to mounting the mixinghead, otherwise the head could spin off if turned incorrectly. See ROTATION for additionalinstructions.

1. Mixing head is submerged.

2. Checkmixer positioning relative to impeller(s) location, off bottomclearance,andimpeller(s) spacing.

3. Rotation of the shaft is correct.

4. Baffles are installed as recommended (if required).

5. If using a speedcontroller, avoid operatingwithin thecritical speed rangeas listedon theMixer Data Sheet.

6. Check the shaft runout to insure that it does notexceed .004” atany point.

CHECK DURINGOPERATION:

1. Mixer is not vibrating on itsmounting stand.

2. Shaft is turning smoothly withoutwobbleor deflection.

3. Bearings arequietandbearing frame iswarm to the touch NOT excessively hot(over 150 degrees F.)

4. All hardwarechecked for tightness periodically.

5. Liquid in vessel is notexhibiting extremevortexing, i.e. themix head is still submerged.

Mixer PositionThe most common applications for high shear batchmixers are done incylindrical tanks of various geometries, andwith goodmixer locationexcellentmixing performance can be achieved. Slight changes inmixer position will have significant changes inmixer performance, andthe following guidelines have proven successful in most applications:

Liquid-liquid, non-vortex conditions

The mixerwill operate satisfactorily in most cylindrical vessels, withfull hemispherical bottoms providing the best flowpattern. Ves-sels can also be conical or dished. Vessels should be selectedwith the smallest diameter and greatest depth provided the shaftlength limits are not exceeded.The best mixing is obtainedwith a vertical mounting, having anoff center from approximately 1/5 to 1/4 of the tankdiameteraway from the vessel center-line. In larger vessels the mixershould be positioned 1/4 of the tank’s diameter (from the tankwall). Where permissible, baffles are recommended in the vicinityof the mixing head, or up to the normal operating liquid level.Either 2 or 4 baffles are advised, with awidth of T / 12, andmoun-ted a distance of T / 72 off of the tankwall (where T = Tankdia-meter). Using baffles allows the mixer to be mounted closer tothe tank center-line without risking severe vortexing.

For liquid-solid, vortex conditions

If a vortex is required (for instance, to drawdown light, poweredmaterials), the mixer should be mounted:ROTOSOLVER: vertically, at approximately 1/6th to 1/5th of thetank’s inside diameter, off center, without baffles. Slight changesin this off center location will make drasticdifferences in theamount of vortex created. The key is to find a location that cre-ates sufficient vortex without entraining too much air.The vortex should never be so big that the mixing head runs dry orpartially dry. Should the vortex extend to the mixing head,movethe mixing heada few inches off vessel center and by thismeans, cavitation will be avoided.If you are unsure, please call an application engineer here atAdmix at 800-466-2369

For liquid-solid Mixing

Powders/solids that sink. Typically granularmaterials like salt,sugar, phosphate:Mount should be 1/5 the tankdiameter off cen-terPowders that float. Typical materials include Carbopol, Car-rageenan, gums, starches, soy proteins andmilk powders: Mountshould be 1/6 the tankdiameter off centerPowders that float but where air entrainment is detrimental to theprocess, such as tablet and pill coatings: Mount should be 1/4 thetankdiameter off center.

Note: Powder pull down rate will be very slow in this configuration

Meat or poultry brine applications: Mount should be 1/5 the tankdiameter off center in cylindrical tanks, andMount should bedead center in square or rectangular tanks

Mixing Head Height

The recommended location of the ROTOSOLVER is approx-imately 1 headdiameter off bottom.When a stronger vortex isrequired, orwhen additional flow /pumping is necessary, werecommend the addition of an upper Jetfoil™ style impeller. SeeIMPELLERS for additional instructions.

In tanks equippedwith other rotating equipment (IE: scrape-surface oranchor sweep agitators):

The mixer head should be located no closer than 3-4 inches fromthe anchor or scraper arms.The mixer should be located directly opposite to the low speedvertical agitator.

Operation InformationThis chapter discusses the following:

Operator Safety Precautions 28Operating the Mixer 28Cleaning 28


Operator Safety Precautions

Always observe the Mixer Data Sheet (MDS)for application data.

Never touch the mix head, or shaft when the mixer is in operation.

Never place or put any body parts into amixing vessel while equipment is operating.

Never touch the in-tank coupling, if equipped, duringmixer operation.

Always observe local noise warnings.

Be aware of HOT surfaces and never touch.

Operating the Mixer


The ROTOSOLVERmixers are designed to operate intermittently under all standard conditions andat normal levels. It is not goodpractice, however to operate continuously when extreme vortexingor surging occurs. All mixers may operate at elevated temperatures and therefore may feel hot totouch. The MAXIMUM Bearing Frame temperature is 160 degrees F.After the mixer has been securely fastened in position and a checkof the Mixing Head rotation hasbeen completed, the mixer is ready for operation.

Turn on the mixer. Allow time enough for the mixing pattern to be established.

Turn Off the mixer. Make any required adjustments to baffles if equipped.

Adjust the mixer position to optimize the mixing.

SeeMixer Position for additional instructions.

If a stronger vortex is required, orwhen additional flow /pumping is necessary, we recommendthe addition of an upper Jetfoil style impeller. See IMPELLERS for additional instructions.

CAUTION:Make sure all fasteners are tightened to the proper torque BEFORE connecting themotor to the power source.

"Bolt Torque Table: Standard Bolts" on page 48

At the end of the first two weeks of service, checkall of the mounting hardware for tightness. SeeAppendix A for bolt torque tables.

CleaningThe majority of ADMIX supplied products have wetted parts that are fabricated from one or acombination of the following stainless steels:

304 is the basicchromium-nickel austenitic stainless steel and is suitable for awide range ofapplications.316 is more corrosion resistant through the addition of molybdenum. This grade is desirable wherethe possibility of corrosion exists.316L is the lowcarbon version of 316.

ADMIX stainless mixers and parts should NEVER be cleanedwithmetal scrapers or come in contactwith carbon steel. Consult chemical supplier for recommended cleaner, concentration, time andtemperature. Care should be taken to avoid any abrasive product which could scratch thesesurfaces.High pressure wash down nozzles should NOTbe directed at any connection which could forcemoisture into the Bearing Frame or electrical motor.For closed tank systems, CIP is the normal method for cleaning. For open tank systems, pressurewash-downwithmanual cleaning via non-metallic brushes or non-contaminated cloth isrecommendedwith the appropriate, compatible cleaning solutions.Clean the mixing headafter use by letting it spin a fewminutes in hot water or a suitable cleaningsolution. Remnants of driedmaterial may have a negative impact on the mixer’s operation. Propercleaning should be carried out immediately after use.Before anymanual cleaning, the operatorMUST insure that the mixers are off and all electricalconnections are locked out.Periodically (once amonth ormore frequently) disassemble the “wet end” of the mixer and inspectthat all surfaces are clean. Reassemble replacing anyO-rings or seals showingwear or damage.

Maintenance Safety Precautions

Never lift or carry the mixing unit by its shaft.

Always observe local personal lifting guidelines and limits.

Always observe local LockOut TagOut procedures.

Lubrication

Lubrication for 85 frames through 180 frame is NOT required. These models are suppliedwith pre-packed bearings. The Bearing Frame has a vent, but NO grease fittings.

Mixer DisassemblyDisconnect the Motor

DANGER:Immediate hazards whichWILL result in severe personal injuryor death.Interlocks should be installed on all personnel access stationsto prevent injury during internal tankmaintenance.

CAUTION:Use proper care and follow local codes when performingworkon any electrical device.

Shut off the electricpower to the Motor and disconnect the requiredwiring to the Motor. Use proper care and follow local codes whenperformingwork on any electrical device.

Remove the Mixer Assembly

CAUTION:DO NOT LIFTORCARRY FROMTHE SHAFT as this could causethe shaft to bend andmay lead to excessive vibration ordamage. Lift the mixing unit from the BEARING FRAME orGEARBOX/MOTOR ASSEMBLY ONLY.

With proper lifting practices, remove the Mixer Assembly from its tank orvessel to a suitable location that will allow for ample space to work onthe unit. Disassembly of these larger units can be performed either in thehorizontal or vertical orientation. Your space andavailable liftingequipmentmay dictate which position fits your situation.

Remove the Motor Mounting Bolts

The Motor is securedwith Hex Head Bolts. Removing the bolts will allowyou to slide the Motor from the frame. BE AWARE THAT THEMOTOR SHAFTMAY STICK TO THEMOTORCOUPLING. The entire Mixer /Motor assemblymay act as one entity. If so, support the entire unit during removal.

Remove the Motor andCoupling

Disengage the Motor Key from the Motor and set the motor aside.

Remove O-Ring

Remove the sealingO-Ring from the upper flange of the Bearing Frame.

Remove the Upper Bearing Retaining rings

There are two (2) Retaining Rings located above the upper bearing:one on the O.D. of the Coupling/Quill Shaft and one on the I.D. of theBearing Frame.

Remove the Mixing Head

The ROTOSOLVERmixing head is completely free of any hardware.The head can be removed or disassembled by unthreading thehead in a clockwise direction (when viewed from above).If the head is “locked” on the shaft from continuous use, we recom-mend that awrench andmallet be used. Apply the wrench to thehead (at the flats) and strike the wrench. Three or four hits shouldloosen the head, which should then unthread from the shaft.DO NOTgrab the mixer headwith awrench UNLESS the hub hasflats machined onto it, nor grab the mixer headat any other loc-ation but the flats. Damage to the mixing headmay result in unsat-isfactory operating conditions.Remove and replace the Teflon gasket /washer ring after dis-assembly.

Remove Impellers

Remove any Impellers from the Shaft.

Remove the V-ring andCladding

Slide the rubber V-ring along the Shaft and remove. The Cladding shouldbe free to be removed from the base of the Bearing Frame and slidalong the Shaft for removal.

Remove the Shaft

Locate the Assembly to a location that will allow for ample space to workon the unit. Disassembly is made easierwhen the Mixer Assembly is in theHORIZONTAL orientation and adequately supported.The lower end of the Shaft has a threadedportion thatMUST beprotected before proceeding furtherwith these instructions. A woodenblock, of hardwood,may be used between the striking device and theend of the Shaft.Dislodge the Shaft from the Bearing Frame by striking the wooden blockwith a large hammer. It is important that you swing the hammerparallelto the Shaft. One or two blows should be sufficient to loosen the Shaftfollowedby several lighter taps to completely drive out the Shaft.The Upper Bearing will followwith the Shaft as it slides out of the BearingFrame. The Upper Bearing will be pushed out by the Lower Retaining ring.This Retaining ringmay need to be replaced if damaged. The LowerBearing will remain in place in the Bearing Frame.

Remove the Lower Seal Retainer

The Lower Bearing can nowbe removed from the Bearing Frame using along drift or rod to drive it out from the top end.

Remove the Upper Bearing

After the shaft is extracted from the bearing frame, remove the bearingfrom the coupling.

Remove the Upper Inner Retaining Ring

Inspection

The Bearing Frame should be empty. Check the inside of the BearingFrame for any deep grooves or other damage whichmay affectreassembly. Pay particular attention to the bearing bores and the O-ringcontact surfaces. Retaining ring grooves should also be checked. Thevent located on the outside of the Bearing Frame should be replaced, ifdamaged ormissing.

Mixer Assembly

Always use NEWBearings, Radial Seal, Retaining Rings, andO-ring when re-assembling a BearingFrame. Inspect all other parts for abnormal wear or damage. Replace or repair any damagedpart.It may be necessary to apply Loctite (or equivalent) compound to the BearingOD to prevent anymovement. Rebuilds should only be done by a qualifiedmechanic.

Note: The Bearing Frame can be assembled by reversing the previous steps. Be sure that allinternal surfaces of the Bearing Frame are clean prior to reassembly.

CAUTION:To prevent bearing damage,make sure both inner and outer bearing raceways areevenly pressed or supportedwhenever possible.

See ""Check Shaft Straightness" on page 21" for specified runout limits.Mount the Mixer so that its shaft is vertical and free to rotate.

Note: If using a support thatmay bemade of carbon steel, takeprecautions to avoid contact between it and the Shaft, Mixer Headassembly or Bearing frame. The mild steel could contaminate thestainless steel and possibly induce corrosion.

Evaluate Runout.Clampadial indicator to a rigid support that can be repositioned alongthe length of the shaft in 8” - 12” increments.

HeatingIndicate the Shaft at a point 8” - 12” from the lower flange .Mark this point“A”. Rotate the shaft to find the point having the greatest runout. Markthis point with a vertical line. If the runout at this point is within the limit,move down the shaft another 8-12". If it exceeds the limit, straighten thisportion of the shaft.With a pinpoint, high heat flame, heat a point located at 180 degreesfrom the vertical line and as close to the Lower Flange as possible withoutburning the V-ring or Seal. The heating point should be no larger than 1/4”in diameter. The Shaft diameterwill determine the amount of time theflame will be held on the Shaft. We recommend the use of propylenewith a brazing tip (size 00 to 3). Do NOT use propane as youwill not beable to achieve a high enough temperature.3-5 seconds of exposure will normally pull .005” - .010” out of the bend forShafts ranging from 1” to 1.5”. 10 - 12 seconds exposure for any size Shaftis the maximum time. The above example assumes that the heat sourceis approximately 3-4 inches away from the indicator.

CoolingAfter heating, quenchONLY the heated spot with an ice coldwet rag.Re-wet, cool, and replace the rag every 15 - 30 seconds. Continue tohold the rag onto the Shaft until all of the heat has been pulled from theShaft.

Repeat as RequiredRotate the Shaft to recheck the runout at point “A”. If the runout is stillover the limit, repeat the heating and cooling only this time move 1”closer to point “A” from the previous heating point.Continue to repeat the steps until the runout is within the limit. Do notheat the same spot twice.Move the indicator to a point 8” - 12” from point “A” and label this point“B”. Rotate the Shaft to check runout at point “B”. Point “A” is now thepoint to apply the heat. Repeat steps heating and cooling until therunout at point “B” is within the specified limit.Continue to move down along the Shaft through points “C”, “D”, “E” (8” -12” between each) until there is no point along the Shaft with runout ofgreater than the specified limit.

Install Impellers

Check the inside of the Impeller and the length of the Shaft for anyburrs, scrapes, or other damage thatmay hinder the Impeller install-ation.Slide the Impeller(s) onto the Shaft and secure at its proper location.See the mixer drawing in"Your Mixer Information" on page 13 for spe-cific details.

Install the Mixing Head

Reassemble the threaded style ROTOSOLVERmixing headbyinstalling a newwasher and threading the head onto the shaft in acounter-clockwise direction (when viewed from above).

Install the Motor Sealing O-Ring

Lubricate and install a newO-ring into the groove of the Bearing Frame’supper flange.

Prepare Motor Key/Coupling

Install the Motor Key onto the Motor Shaft. Align the Motor shaft with theMotorCoupling. Slide the Motor into the Coupling.

Install the Drive Motor

Align the holes of the upper flange with the tapped holes of the C-Face.

Install the Motor Mounting Bolts

The Motor is secured to its Bearing Frame Assembly with Hex Head Bolts.

Bearing Frame Vent (BVENT)

Older versions of this feature included a plasticassembly. Newermixermodels are equippedwith a stainless steel version. The stainless steelversion can be retrofitted into any bearing frame that already has thetapped hole.TO REPLACE AND/OR INSTALL THE BEARING FRAME VENT:Remove the plastic vent assembly from the Bearing Frame. Youmayfind that grabbing the Vent Capwith channel lock style pliers may allowyou to remove the Vent Housing. Remove the Vent Housing using astandard 15/16”wrench.Make sure that the threads are clean and noburrs exist.Make sure that the Seal Washer is installed onto the Vent Housing.Thread the Vent Housing into the Bearing Frame. Tighten securely,being careful not to over tighten and destroy the Washer. THEWASHERSHOULD BE COMPRESSED ANDCREATE A SEAL AGAINST THE BEARINGFRAME.BE SURE THAT THE VENT HOUSING IS TIGHTENED.ONCE THE VENTCAP ISINSTALLED, IT BECOMESDIFFICULT TO TIGHTEN THE HOUSING.Using a rubbermallet, or other soft headed hammer, tap the Vent Caponto the Vent Housing.

Wire the Motor

DANGER:Immediate hazards whichWILL result in severe personalinjury or death.Interlocks should be installed on all personnel accessstations to prevent injury during internal tankmaintenance.

CAUTION:Use proper care and follow local codes when performingwork on any electrical device.

Motormust be installed in accordance with all applicable federal,state and local electrical codes.Connect the motor via an overload protection device and checkfor proper rotation. Each ADMIX product is suppliedwith a rotationalarrow for ease of reference.Mixer Shaft rotationmust be CLOCKWISE, when seen from abovethe mixer.Use proper care and follow local codes when performingwork onany electrical device. Connect the electricpower to the Motor.
