    INTRODUCTION

    Syntron Model “MF” Electromechanical Vibratory Feeders are designed to provide an effective method of

    conveying and controlling the flow of bulk material.

    These feeders consist of a trough assembly spring coupled to a vibratory drive (rotary exciter). The rotary

    exciter utilizes a rotary electric vibrator to impart vibration into the system. The vibratory forces developed

    by the unbalanced weights are magnified through the compressed polymer springs to provide vibration onthe trough assembly.

    Supporting information, such as drawings, may be attached to this manual. The information containedtherein take precedence over corresponding information printed in this manual.

    THEORY OF OPERATION

    The principle of “MF” Feeder operation is to produce a constant vibrating stroke of the feeder by driving thetrough down and back, then up and forward. This action projects the material into flight and when the

    2

  • 8/16/2019 SM3204 MF-400-E (1)

    3/19

    material falls to the trough surface, it lands at a new location further along toward the discharge end. The

    drive motion then drives the trough up and forward, carrying the material still further along the trough.

    This action, constantly repeated at high speed, sends the material smoothly along the surface of thetrough.

    Flow capacities are varied by: changing the depth of material discharging from the hopper, changing the

    stroke of trough vibration through adjustment of the unbalanced weights or during normal operation bymeans of the control rheostat, varying the power to the motor.

    LONG TERM STORAGE

    When received, the equipment should be carefully uncrated. If the feeder assembly is shipped mounted onskids the skids should remain on the feeder until installation.

    Give the equipment a thorough visual inspection to reveal any damage that may have occurred duringshipment. If damage is found, notify the shipping carrier and FMC Technologies promptly.

    If the feeder must be stored for an extended period, it is advisable to store it indoors.

    The drive springs and cable assembly must be protected from extreme heat, sunlight, oil, grease, o

    chemicals, which deteriorate rubber compounds. If the feeder is stored outdoors, store controller in an

    inside storage area. Place feeder on sufficient cribbing to protect from water.

    Caution:  Do not support the weight of the unit by the exciter assembly. This will distort and

    damage the springs by placing undue strain on them.

     Apply oil or rust preventative to hardware and completely cover the unit with waterproof covering.

    When storing the controller, plug all openings in the control box to prevent dirt, rodents and insects from

    entering. FMC Technologies advises placing a corrosion preventative inside the control box. Cover the

    controller and motor and place in an area protected from extreme heat. Do not drop the controller or theforce of the impact may damage the components.

    HOPPER DESIGN

    Refer to Figure 1.The “Recommended” hopper with a T/H ratio of .5 shows a uniform flow pattern to the feeder trough

    Material at the front and rear of the hopper moves at nearly the same velocity, and the depth of material “d”is nearly equal to the hopper gate height. The “Recommended” hopper design allows the most economica

    feeder to be used.

    The “Acceptable” hopper design may require a slightly larger feeder than required for the “Recommended”

    design. This is due to the non-uniform flow pattern of material at the rear of the hopper. Material flow

    velocity is reduced, material depth “d” is reduced… and a reduction in feeder capacity is realized. A T/H of.5 to 1.0 is generally acceptable. However, when the T/H ratio exceeds this range, the material flow

    patterns distort drastically and will significantly reduce feed rates.

    1. Rear wall angle “A” should be steep enough to permi

    material flow (60° or more).

    2. Front wall angle “B” should be just enough to permi

    material flow (5° less than “A”).

    3. Throat dimension “T” for random size material should

    be 2 times largest particle of material, or whereparticles are nearly same size (near size) “T” is 4 timeslargest particle size to prevent blockage at throat

    opening.

    4. Gate opening “H” must be a minimum of 2 times the

    largest particle of material and should increaseproportionally for the desired capacity. The moseconomical feeder is selected when the throat

    dimension “T” is equal to or slightly larger than H/2. I

    “T” is greater than “H” the flow pattern of the material isdisturbed resulting in non-uniform flow.

    5. The width of opening “D” for random size materiashould be 2 times the largest particle.

    “H” should be between 1.2 to 1.5 times “d” where “d” is

    determined by:

    “d” = Capacity x 4800W x Flow Rate x Density

    Capacity = w x Flow Rate x Density x “d”

    4800Capacity = Tons/Hr

    W = Feeder width in inchesFlow Rate = Ft/minDensity = lbs/ft3

    D = Material depth of flow

    FEEDER INSTALLATION

    WARNING: Do not handle the feeder unit by the eyebolts located on the exciter assembly. Use the

    mounting assemblies for handling the feeder.

    CAUTION:  Never make any alterations to the feeder without first contacting FMC Technologies

    FMC Technologies will not assume any responsibility for feeder performance as the result of any

    unauthorized alterations to the equipment!

    Hanger assemblies are provided on the feeder for suspending the unit from an overhead mounting suppor

    with the use of flexible steel cables.

    4

  • 8/16/2019 SM3204 MF-400-E (1)

    5/19

    FMC Technologies recommends the use of extra flexible wire ropes. The MF-400 requires a minimum

    diameter of 3/8” for the discharge suspension assembly and ” for the inlet suspension assembly. SpeciaMF-400 Feeders weighing more than 20% over the standard weight should be 5/8” diameter wire ropes.

    The suspension cables must be as near vertical as possible and installation must be in accordance with the

    arrangement drawing.

    The feeder must be kept level transversely, but may slope down longitudinally toward the discharge end by

    as much as 15° (a 10° downslope is standard).

    The feeder must never come in contact with any rigid object or adjacent surface that could hamper itsvibration action.

    WARNING: Suspension mounted feeders must be equipped with safety cables.

    Safety cables will prevent the feeder from falling into the work area below in the event a suspension cable

    should break. The size of the safety cable should be equal to the size of the wire rope used on the rea

    suspension.

    The safety cables should be hung from a substantial support. They must be attached to the feeder troughat the safety lugs only. The length of the safety cables must be sufficient so that the vibratory action of the

    feeder is not hindered.

    CONTROLLER INSTALLATION

    When uncrated give the controller a thorough visual inspection to reveal any damage that may have

    occurred during shipment.

    CAUTION:  For multiple feeder installations each controller is designated for a particular feeder. I

    is very important that the proper controller is wired to its matching feeder. Unless the propecontroller is wired to the proper feeder, the required performance will not be obtained!

    The controllers are marked with a number on the inside panel and the feeder is marked with a

    corresponding number adjacent to the nameplate on the feeder wing plate.

    When installing the controller, refer to the wiring diagram shipped with the controller.

    CAUTION:  The conductor between the feeder and controller must be of a size sufficient to carry

    the current and voltage as stamped on the equipment nameplate. The voltage drop through aconductor of insufficient size for the required distance could result in a lack of feeder stroke during

    operation. See wiring diagram included with the controller.

    WARNING: Electrical power supply connection to the FMC Technologies supplied controller mus

    be made through a customer supplied safety disconnect switch which must be mounted next tocontroller. Aside from the hazard of electrical shock, if the drive unit should be accidentally

    energized, the rotating weights could cause severe physical harm to the personnel and damage to the

    exciter unit itself.

    OPERATING FREQUENCY

    The operating frequency of each feeder is pre-determined by FMC Technologies. The unit will be taggedwith the maximum input frequency. The operating frequency should never exceed this value. Additionally

    the minimum operating frequency is 40 Hz for all units. Always keep the operating frequency within theselimits. The VFD control supplied by FMC Technologies will be pre-programmed with the correct operating

    parameters. If the VFD is supplied by others the correct operating parameters must be programmed prioto use.

    It should be noted that a VFD control is required to operate these feeders. If the feeder is operated straigh

    off the line power the feeder will exceed its maximum operating speed and could lead to failure of themachine. Always use a VFD with the correct parameters to ensure optimized feeder performance an

    avoid potential damage.

    Regardless of the incoming power, the VFD will be set to operate the unit at the correct operating speedThis holds true for 50 Hz power. The maximum operating frequency will always be greater than 50 HzRefer to the frequency tag supplied on the feeder for the operating frequency information and ensure tha

    the control is set up to control the unit within this range of frequencies.

    INSTALLATION CHECKS

    WARNING: The power supply voltage and frequency must correspond to nameplate ratings andthe unit must be properly grounded.

    1. Do the leads for the motor correspond to the numbers marked on the output side of the terminal block

    at the controller?

    2. With multiple feeder installations, is each controller wired to its matching feeder?

    3. Are the wiring connections between feeder, controller and power supply, securely made and in stric

    accordance with the wiring diagram supplied?

     After feeder controller installation has been completed, momentarily energize the equipment and observethe direction of the motor rotation. The motor must be rotating in the direction as indicated by the arrowlocated on the sheave cover guard. Refer to the figure below. To reverse the direction of the motor

    reverse any two of the motor leads T1, T2 or T3.

    With the feeder and controller properlyinstalled and the wiring complete, the

    equipment is now ready for operation.

    NOTE: For operating procedure, refer to the

    separate instructions supplied for the specificmodel controller.

    FEEDER MAINTENANCE

    Owing to the simplicity and ruggedness o

    construction, very little maintenance will be

    6

  • 8/16/2019 SM3204 MF-400-E (1)

    7/19

    required on the feeder. However, the following points should be given careful consideration:

    1. Initial lubrication of the equipment was performed at the factory. The rotary electric vibrator will requirelubrication! It is very important the equipment is properly lubricated.

    The rotary electric vibrator used can vary depending on the application. Check the nameplate on the

    rotary electric vibrator to obtain the model number and manufacturer. Lubricate the rotary electricvibrator per the recommendations of the manufacturer. Use the type of grease recommended by themanufacturer and lubricate with the proper amount at the recommended frequency.

    If the grease used is changed to another type or brand, the bearing must be thoroughly flushed

    beforehand.

    2. Some materials tend to adhere to and build up on the trough surface. This must be removed as a dailypractice.

    3. On a monthly basis:

    (a) Check feeder and exciter stroke, they must not exceed the design limits of the feeder unit

    Refer to Feeder Stroke section.

    (b) Check the isolator springs and eyebolts (if suspension mounted) for any signs of wear. No

    chattering or impact noises should be heard.

    (c) Check controller for any visible signs of component wear, particularly relay contactors.

    4. If maintenance is required on the rotary electric vibrator, be sure it is performed to the rotary electric

    vibrator manufacturer’s specifications.

    STROKE

    Trough stroke is the distance the trough surface travels on one complete cycle of vibration.

    Total stroke is the combined sum of the trough stroke and exciter stroke.

    For the MF-400 the total stroke should not exceed 0.6”. (example: 0.29” on he exciter and 0.31” on thetrough).

    Normally, capacities will be attained at a lesser total stroke.

    Stroke gauges are located on the side of the wing plate on theright side of the feeder and on the top of the exciter housing

    opposite the sheave side. See Figure 3.

    Under vibration a “V” will appear on the gauge. The stroke of theunit can be read at the apex of the “V”. Refer to Figure 3. Thgraduated lines will appear solid black.

    THRUST ADJUSTMENT

    The thrust of the rotary exciter drive unit is varied by rotating the outer counterweights at each end relativeto the fixed inner counterweights.

    To adjust, follow this procedure:

    WARNING: Before performing any maintenance work, the electrical power supply must be

    disconnected at the safety disconnect switch.

    1. Remove the side cover panels from the wingplates and remove both end covers from each end o

    the rotary electric vibrator. Loosen the counterweight clamping screws of the outer counterweights

    at both ends of the rotary electric vibrator. Note: The inner counterweights will have graduatedthrust scales to indicate the percentage thrust. Use these scales to properly set the thrust.

    2. Rotate the outer counterweights to the position that gives the desired resultant force.

    WARNING: Set both ends to exactly the same setting on the scales. Any differences wil

    cause improper motion which can cause damage to the unit.

    3.  After ensuring the counterweights at each end have been set at the proper setting and lined u

    perfectly with each other, set the torque of the counterweight clamping bolts per the

    recommendation of the rotary electric vibrator manufacturer. Refer to the manufacturer’s serviceinstructions for the proper torque settings. 

    4. Replace the end covers on the rotary electric vibrator and the side cover panels on the wingplatesThe rotary exciter is ready for operation.

    REMOVING & REPLACING ROTARY ELECTRIC VIBRATOR

    To remove the rotary electric vibrator from the feeder follow these instructions. It should be noted that it is

    recommended that the rotary electric vibrator be removed from the mounting plate rather than removing themounting plate with the rotary electric vibrator.

    Note: This process requires two workers. Estimated time is 1.5 hours.

    Step 1. Shut off power and lockout prior to beginning work.

    Step 2. Gather all needed tools.

    One (1) ” Impact Wrench

    Two (2) SocketsOne (1) Pull HandleOne (1) Torque Wrench

    One (1) Pry Bar 

    Two (2) Chain Hoists or Come-Alongs (capable of safely handling 500 LBS)

    Step 3. Remove the four (4) vibrator mounting bolts using the impact wrench, sockets, and pull handle.Loosen the nuts from underneath the unit with the impact wrench while holding the bolt heads securely with

    the pull handle from the top side of the unit. Note that the bolts can be loosened from either the top or 

    bottom of the unit depending on accessibility.

    11/19

    Step 6. Maintain a slight amount of tension on the side opposite the removal side by adjusting the force

    with the hoist. Use the hoist on the removal side to pull the vibrator outward toward the wingplate. This

    process requires two people to constantly adjust tension in each of the two hoist chains.

    Step 7. Keep tension in the side opposite removal while the vibrator is pulled toward the wingplate. Thiswill prevent the vibrator from swinging out of the unit. Lower the vibrator to the floor using the hoist.

    At this point the old vibrator is removed from the exciter and a new vibrator is ready to be installed.

    To install the new vibrator follow the following steps.

    11

  • 8/16/2019 SM3204 MF-400-E (1)

    12/19

    Step 8. Place the hoist lifting hooks on the vibrator lifting lugs as noted earlier in Step 5.

    Step 9. Lift straight up on the new vibrator using the hoist on the side of entry. Use both hoists

    concurrently to lift and pull the vibrator near the hole in the wingplate.

    Step 10. Use a pry bar to position the vibrator mounting surface correctly with the vibrator mounting plate.

    Pull the vibrator into the exciter with the opposite side hoist while maintaining a safe tension with the near side hoist.

    12

    13/19

    Step 11. Use a pry bar to line up the vibrator mounting holes with the mounting holes in the bottom plate.

    Install the vibrator mounting hardware. Use an impact wrench and pull handle to partially tighten the

    vibrator mounting hardware.

    Step 12. Use a torque wrench to set the bolt torque to the proper value. Consult the rotary vibratormanufacturer’s maintenance instructions for the proper bolt torque for the vibrator clamping bolts.

    Step 13: Reset the thrust at each end of the rotary electric vibrator to the setting on the previous vibrator.Replace the end covers when complete.

    Step 14. Replace the side cover panels on the wingplates. Connect new vibrator to power source. Thefeeder is now ready for operation.

    REMOVING EXCITER

    It is unlikely that the exciter will ever require removal from the feeder. However, if the exciter must beremoved from the feeder, follow the procedure below.

    CAUTION:  The exciter assembly is heavy and difficult to handle. While performing work on the

    exciter be careful that all cables, supports, and hoists, etc., are of sufficient strength.

    WARNING: Do not attempt to manually handle the exciter.

    For ease of removal, FMC Technologies recommends removing the exciter from the bottom of the feederIf there is not sufficient clearance to permit removal for the bottom, the rear compression plate may beremoved and the exciter removed from the rear of the feeder.

    To remove exciter from bottom of feeder:

    WARNING: Before performing any maintenance work, the electrical power supply must bedisconnected at the safety disconnect switch.

    1. Remove cover from junction box; mark and disconnect each lead.

    2. Mark the right side of the exciter and the wing plate of the same side of the feeder. This will beimportant when replacing the exciter assembly.

    3. Remove the safety angles from underneath the exciter on both wingplates.

    4. To facilitate removal of exciter, attach cable of sufficient strength (exciter weight is approximately 2100

    pounds) to the exciter at the four corners. Refer to Figure 4. Hold all cables secure by using a hoist osimilar equipment.

    WARNING: These cables will be supporting the entire weight of the unit while removing the

    exciter.

    Note: For ease of removal and replacement it is advisable to insert four ”-10 x 1 ” eyebolts in thecorners of the housing (bottom side). To these eyebolts, secure a guide chain or cable from the exciter uni

    to the trough support member near the discharge end of the trough.

    Refer to Figure 4. This will help in keeping the exciter at an approximate 30 degree angle and will hold the

    exciter in place till all the bolts are removed.

    5. While support cables are tight, carefully remove the capscrews, which secure the front and rear drive spring

    assemblies to the exciter unit only.

    6. Back off the rear drive spring mounting bracket by loosening

    the cap screws which secure the spring bracket to the feeder wing plate.

    CAUTION:  Loosen but do not remove or run these bolts

    to the end of their threads!

    7. With approximately ” clearance between the exciter and drivespring assemblies slowly lower the exciter from its position.

    WARNING: The exciter is heavy, all personnel must be kept clear of this area.

    The rotary exciter assembly is now ready for disassembly.

    corners of the housing (bottom side). To these eyebolts, secure a guide chain or cable from the exciteunit to the trough support member near the discharge end of the trough.

    Refer to Figure 4. This will help in keeping the exciter at an approximate 30 degree angle and will hold

    the exciter in place till all the bolts are removed.

    4. While support cables are tight, carefully remove the cap screws which secure the front and rear drivespring assemblies to the exciter unit only.

    5. Using support guide cables described in Step 4, hold exciter in place till all cap screws are removed

    from drive spring brackets. Remove rear drive spring bracket, rear drive springs, and rotary exciter asa single unit by removing the cap screws which hold the drive springs bracket to the feeder wing plate.

    6. Carefully let the exciter and spring assembly attain a vertical hanging position. Lower the assembly to

    the floor and remove the drive spring assembly from the exciter.

    The exciter is now ready for disassembly.

    REPLACING EXCITER

    Before replacing the drive unit, FMC Technologies recommends the springs be inspected for defects, wearand possible replacement.

    If the exciter was removed from the bottom of the unit, replace by the following method.

    1. Using cables as explained in Step 4 of the removal procedure, align the drive unit against the front

    spring group. Make certain the unit is centered between the feeder wing plates and the marked side othe exciter is on the same side of the feeder as the marked wing plate. (This was noted in Step 2 of theremoval procedure).

    2. Bolt the front drive spring group to the exciter.

    3. Bolt the rear spring group to exciter and replace any shims that may have been between the spring

    mounting bracket and feeder wing plate.

    CAUTION:  Torque rear compression plate bolts uniformly and as specified on the Genera

     Arrangement drawing.

    4. Remove the guide and support cables and eyebolts from the bottom of exciter.

    5. Connect motor leads and pack the junction box to prevent loosening of connections, replace the

     junction box cover.

    15

    16/19

    6. Check the feeder stroke, that is, the sum total of the exciter and trough vibration stroke. If in excess of

    0.6” an adjustment of the exciter thrust will be required.

    For instructions concerning feeder stroke and thrust adjustment refer to pages 7 and 8.

    If the exciter was removed from the rear of the feeder, replace by the following method:

    1. Replace rear spring group and compression plate to the exciter.

    2. Using cables as explained in Step 4 of the removal procedure, align the drive unit against the fronspring group. Make certain the unit is centered between the feeder wing plates and the marked side o

    the exciter is on the same side of the feeder as the marked wing plate. (This was noted in Step 2 of the

    removal procedure.)

    3. Bolt the rear spring compression plate to the feeder wing plates, do not tighten these bolts.

    4. Bolt the front drive spring group to the exciter. Replace any shims that may have been between the

    rear spring compression plate and the feeder wing plates.

    CAUTION:  Torque rear compression plate bolts uniformly and as specified on the Genera

     Arrangement drawing.

    5. Remove the guide and support cables and eyebolts from bottom of exciter 

    6. Connect motor leads and pack the junction box to prevent loosening of connections, replace the junction box cover.

    If the feeder is equipped with a speed control device, connect the speed control cable to the magne

    assembly. Then replace the speed control cover.

    7. Check the feeder stroke, that is, the sum total of the exciter and trough vibration stroke. If in excess of0.6” an adjustment of the exciter thrust will be required.

    DRIVE SPRING REPLACEMENT

    If it is necessary to replace a drive spring, it is recommended that all springs, rather than just one, bereplaced. To replace springs:

    WARNING: Before performing any maintenance work, the electrical power supply must bedisconnected at the safety disconnect switch.

    1. Reposition the safety angles at the bottom of the trough under the exciter unit to their higher position byreinstalling the hardware into the lower set of holes in the safety angles. Add jack screws into the

    tapped holes of the safety angles and run them up until they make contact with the bottom of theexciter. This will support the exciter during spring replacement.

    2. Remove the four bolts located at the outside corners of the rear compression plate and install ”-16 all

    thread in the holes. Use the nuts and washers from the previously removed compression plate bolts.

    3. Evenly remove the remaining bolts from the rear compression plate. Skip from one bolt to another in

    an alternating pattern on each side. Continue bolt removal until the pressure is off the rea

    16

  • 8/16/2019 SM3204 MF-400-E (1)

    17/19

    compression plate. Normally, the bolts will need to be completely removed to take all the pressure of

    the rear compression plate. Leave the all-thread in place to hold the rear compression plate during

    spring changeout. There are normally shims placed between the rear compression plate and bolt barsof the wingplates. When the pressure is removed from the rear compression plate, remove these

    shims and store them until the new springs are ready to be installed.

    CAUTION:  Do not remove the all-thread

    during the spring changeout process.Loosen the nuts as needed to remove the

    pressure from the rear compression plate.

    4. Replace only one spring assembly at a time.Remove the inside (front) spring set first by

    removing the bolts holding the spring set to the

    exciter and front compression plate. The four jack screws in the safety angle may be used toadjust the exciter vertically to align the bolt

    holes as needed. Install the new front springset.

    5. Remove the rear drive springs and install the new rear spring set.

    Note: The spring groups are assembled with each rubber portion offset from the centerline. When

    replaced, the springs must be positioned as shown in Figure 6.

    6. Insure that all the drive spring hardware is tight. Clean the mating surfaces of the wingplates and rea

    compression plate so that all rust or material build-up is removed.

    7. Clean the shims (if originally supplied) thoroughly to remove all rust and material build-up. Replace the

    shims between the wingplates and rear compression plate.

    8. Use the all-thread to pull the rear compression plate inward until the new rear compression plate

    hardware can be installed. Always use new hardware to fasten the rear compression plateInstall new bolts, nuts, and washers into all holes of the rear compression plate. Torque the reacompression plate bolts to 300 ft-lb dry or 220 ft-lb lubricated.

    CAUTION:  Torque rear compression plate bolts uniformly to 300 ft-lb dry or 220 ft-lb lubricated.

    9. Lower the safety angles back to their original position and remove the four jack screws. The feeder is

    now ready for operation. Please consult FMC Technologies for further direction if the trough or exciterstrokes have varied since the spring changeout.

    Due to the action of new springs the stroke of the feeder may require adjustment and a change in excitethrust may be required. Refer to page 8.

    This completes the spring replacement procedure. The unit is now ready for further operation.
