  • For most bulk material elevating jobs. . . there's a Link-Belt BucketElevator that will handle themefficiently and economically. Withover 100 years of proven experienceas a pioneer and leading producer ofbucket elevators, FMC Technologiesoffers a standardized line of Link-Belt elevators proven in thousandsof installations.Standardization is a standout featureof Link-Belt Bucket Elevators. Link-Belt Type 1 and Type 7 BucketElevator designs are standardized soyou benefit from the economics ofmany stocked components.Manufacturing methods arestandardized through exactingproduction and fabrication to assurecompatibility of components.Engineering and order processingprocedures have also beenstandardized so that the selectedelevator will accommodate yourneeds with a minimum of time andcorrespondence.Balanced design of components,manufacturing craftsmanship, andthe quality found in all Link-Beltproducts, have all helped the Link-Belt Bucket Elevator achieveuniversal acceptance.Two basic designs of bucketelevators are available, and selectiondepends primarily on the material tobe handled.The Centrifugal Discharge designhas spaced buckets that travel at arelatively high speed. It is a mediumcapacity unit, capable of handlingmaterials with small-to-medium sizelumps. The buckets dig the materialfrom the casing boot section anddischarge it by centrifugal force.Type 1- Elevators of this type meetthe service requirements of themajority of installations usingcentrifugal discharge elevators. Thehead shafts are fixed, with the footshaft takeup being internal gravitytype. Buckets are designed for useon either chain or belt.

    For most applications, chain isrecommended, however, belting isused when handling materials thatmust not be contaminated or formaterials that are extremely abrasiveand corrosive.

    As an alternate to the standardType 1 centrifugal dischargedesign, Type 2 design isavailable. The head shaft isadjustable and the boot shaftfixed to maintain the relationshipof buckets to the inlet spout andcurved bottom plate. Type 2bucket elevators arerecommended when handlingfood products; for materials thattend to pack or build-up, or whenhandling materials having alarge percentage of lumps.

    The Continuous Discharge Designhas buckets mounted continuouslythat travel at a much slower speed.The continuous discharge designelevator handles a variety ofmaterials from fines to large lumps.Materials that are difficult to pick inthe casing boot section or friable arenormally handled in this typeelevator. The buckets are fed directlyfrom a loading leg or chute and areemptied by gravity at the dischargepoint.Type 7-This elevator is the mostfrequently used of the continuousdischarge design. The head shaftsare fixed, with foot shaft takeupsbeing internal gravity type. Bucketsare steel and spaced continuouslyon a strand of chain.

    As an alternate to the standardType 7 continuous dischargedesign, the Type 8 design isavailable. The head shaft isadjustable and the foot shaft isfixed. Type 8 elevators are usedfor the handling of fine orcrushed materials with lumpsnot exceeding 1/2 inch. With theaddition of a loading leg and acorrespondingly higher inletspout, this type elevator canalso be used for handling lumpsup to 41/2 ".

    The superior performance deliveredby the Link-Belt Bucket Elevator isthe result of quality components,and each component described inthis catalog has been developed asan integral part of a carefullyengineered elevator design. FMCTechnologies maintains a largeinventory of bucket elevatorcomponents to meet yourreplacement needs.Let our FMC TechnologiesRegional Field Specialist helpyou with your selection of theproper Link-Belt Bucket Elevatorfor your existing or proposed bulkmaterial handling installation.CAUTION: Link-Belt Bucket Elevatorsmust be installed, operated andmaintained in accordance withaccompanying FMC TechnologiesService Instructions. Failure to followthese instructions can result in seriouspersonal injury, property damage or both.Service Instructions accompany theshipment of equipment. It additionalcopies of Service Instructions arerequired, they are available free of chargefrom FMC Technologies, MaterialHandling Solutions, Box 1370, Tupelo,Mississippi 38802.

  • Prior to the selection of a Link-BeltBucket Elevator, all specifications ofthe application and conditions of theinstallation should be reviewed. As aguide to be used in selecting themost efficient and economical Link-Belt Bucket Elevator for anapplication, the following outline isoffered:

    1. Material Characteristicsa. Abrasive, free-flowing, sluggish,temperature, fluffy, friable,degradable, etc...b. Weight per cubic foot at loadingpoint into the bucket elevator.c. Maximum and average size oflumps- percentage of lumps.

    2. Maximum discharge rate (t.p.h.)required of bucket elevator.

    3. Center to center dimensionsbetween head shaft and foot shaft.

    4. Operating conditionsa. Indoors b. Outdoorsc. Corrosive atmosphere, etc...

    5. Type of service requireda. Continuousb. Intermittent

    6. Calculate the volumetric capacityrequired (cubic feet per hour)

    Maximum discharge rate(t.p.h.) x 2000 pounds

    Material weightper cubic foot

    7. Determine the proper type ofbucket elevator required, basedupon the material being handled.Refer to Table #1. If a specificmaterial is not listed withintabulations, select a materialhaving similar characteristics.

    8. With reference to volumetriccapacity and percent of lump size,determine bucket elevator numberusing the selection tabulationsprovided. These tabulations alsoindicate head shaft size andrequired horsepower.

    NOTE: If the "weight per cubicfoot" is isolated between givenvalues, apply the next higherfigure.

    Example #1:Material. . . . . . . . . . .bituminous coalWeight . . . . . . . . . . .50#/cu. ft.Capacity. . . . . . . . . . .70 t. p. h.Maximum lump size under 1/2 inchShaft centers . . . . . . 65 ft.Service . . . . . . . . . . .8-10 hrs. per dayStep ADetermine volumetric capacity.70 x 2000 = 2800 cu. ft./hr.

    50Step BDetermine type of elevator. Table #1indicates either a Type 1 or Type 7.However, capacity is greater than aType 7 will handle. Select Type 1.Step CRefer to selection tabulations andselect a #134 elevator rated 3120cu.ft./hr. for 65 ft. cntr. A 3 7/16"diameter head shaft and 15 hp driveis required.NOTE: A #134 elevator is fullycapable of handling the 1/2"andunder lumps.

    Example: #2:Material . . . . . . . . . . crushed limestoneWeight . . . . . . . . . . . 85-90#/cu. ft.Capacity . . . . . . . . . 75 t.p.h.Maximum lump size 3/4 inchShaft centers. . . . . . .50 ft.Service . . . . . . . . . . .8-10 hrs. per dayStep ADetermine volumetric capacity.75 x 2000

    NOTE: Use light weight for volumeand heavy weight for horsepower.

    Step BDetermine type of elevator. Table #1indicates a Type 7 for this material.

    Step CRefer to selection tabulations. A #781elevator is rated 2090 cu. ft./hr. using100#/cu. ft. and 50 ft. centers. A 315/16''diameter shaft and 15 hp drive isrequired. 3/4'' lumps are within thecapabilities of this elevator. A #781elevator using Steel Bushed Chainrather than Combination Chain ispreferred, since the material beinghandled is mildly abrasive.
