The characteristic profile of thebottom plates provides high rigidity even with a pan widthexceeding 2,000 mm. Deep-Drawn Pan Conveyors may bedesigned with slopes matchingthe angle of repose of the conveyed material. Stiffenerspressed into the side walls ofthe pans as well as a specialsealing edge increase the pan’ssolidity and the dust-tight fitting between the pans.
AUMUND attach particularimportance to the design offeed chutes and dust hoods.Proper dimensioning of dedusting connections in thetransfer areas considerablyreduce the need for cleaning.Weather covers, chutes for collection of fines, distributionchutes and flat gates completethe product range.
The pan conveyors are drivenby bevel spur gears either footmounted with flexible couplingbetween gearbox and driveshaft or shaft-mounted. Forinclined conveying, the gearbox is fitted with a back stop. A hydraulic coupling is installedbetween gear box and motoror, for soft start up of themotor, with a flexible coupling.
Alternatively, the flexible coupling between motor andgearbox can be provided with a disc brake to stop the fullyloaded conveyor in any given position if the back stop fails to work properly. Frequencyconverters adapt the conveyingspeed to the actual conveyingcapacity, thus minimizing wearand ensuring a longer servicelife of chains, rollers and rails.

Deep-Drawn Pan Conveyor with bafflestype KZB-Q 250
Tightness of side walls
Clinker silo feeding type KZB-Q 250
Feeding and discharge - type KZB-Q 250
Standard Deep-Drawn Pan Conveyors with baffles areapplied for inclination angles up to 40°. The basic concept ofthis economic inclined conveyor includes the use of standard elements like deep drawn pans,chains and rollers.
The Deep-Drawn Pan Conveyor type KZB-Q 250 is designed forinclination angles between 28°and 40°. These slopes are stillpracticable for walkways in conveyor bridges.
The AUMUND range of conveyorchains shown on page 9 is designed for lifts of more than 60 m. With an efficient plant layout, feeding of clinker siloscan thus be performed with justone conveyor.
Standardized components reducethe variety of parts and constitutethe AUMUND modular system:components such as sprockets,chains, rollers and rails ofAUMUND pan conveyors areinterchangeable to a large extent,an important asset for spareparts management.
The deep-drawn pans are equipped with baffles for inclinedconveying. These baffles are bolted to the bottom plate andhold in a loose fitting by camswhich arepressed into the upperpart of the side boards.The loosefitting allows the baffles to bendin case foreign bodies get ontothe conveyor. Bent baffles willnot affect proper functioning of the conveyor, they may bereplaced at any time, for exampleduring a regular stop of thesystem.

As a standard, the rollers ofAUMUND pan conveyors areseparated from the traction element, the chain. This important design feature ofAUMUND pan conveyorsensures that the chain selectionis always made to suit the actual traction force, whereasthe rollers are chosen in accordance with the weight ofthe pan conveyor itself and the conveyed material. Theseparation of traction elementsand carrying elements simplifies maintenance andassembly.
All rollers are fastened to theirbrackets by means of stubshafts, a simple but efficientand safe fixing means.Depending on the respectiveplate width, rollers are arrangedat intervals of 500, 1,000 or1,500 mm.

AUMUND Bucket ApronConveyors type BZB 250 arethe proper solution for clinkertransport systems with up to 60° inclination. These conveyorswith their narrow curve radius offer considerable advantages particularly for the modernizationor conversion of existing plantswhere only restricted space is available.
The modular system also appliesfor the AUMUND Bucket Apron Conveyor, ensuring interchangeability and combinationof components like those used forthe construction of Deep-DrawnPan Conveyors. Standardizedchains are used as well; merely the angular fishplates are modified
for the solid bucket fixing. The standard chain sizes are documen-ted on page 9. The roller selectionsuits the bucket size and the loadrequirements. Standard roller diameters are diameters 108/140and 160 mm.The standard rollerspacing is 1,000 mm which meansthat one out of two buckets is fitted with a set of rollers. Same asthe deep drawn pan conveyor, theBucket Apron Conveyor featuresthe proven roller brackets and stubshafts to fasten the rollers.
An essential asset of AUMUNDBucket Apron Conveyors - the tightbucket arrangement - above alltakes effect where very fine-grained clinker with a high ratio of dust has to be conveyed. To
increase the buckets solidity andensure safe operation, the bucketbottom is provided with a built-instiffener. Depending on the individual plant requirements, the overlapping of the buckets is either forward or backward.
• Slopes up to 60°• Lifts exceeding 60 m• Minimum curve radius 8 m• Tight bucket arrangement for

The reduction factor is basedupon the assumption that thematerial in the bucket will forman angle of repose of at least25°. If feeding of the material is arranged in the inclined sectiononly, a higher reduction mustbe accounted for as the factorwill decrease gradually to awater filling level.
In particular large buckets witha width of 1.200 mm and morerequire adequate design of thefeed chutes. For a uniform bucket filling, feed chutes withsaddles have proved to be agood solution, as they ensureeven material distribution overthe whole bucket width. Expertplanning of the chute system istherefore considered to be apre-requisite for trouble-freeoperation with only little dustgeneration.
The take-up station standardprovides for spring tensioning. In special cases counterweightsare added where considerablechain elongations resultingfrom considerable temperature differences of the conveyedmaterial have to be compen-sated. C-shaped cleaning scrapers arranged around thetake-up station and recyclingthe collected fines, are used tominimize cleaning around thetake-up station. Depending on the contents of fines in the conveyed material, the operating time of thesecleaning scrapers can be adjusted by means of sequencecontrol. For the drive stationarea, fines collecting chutes are the most suitable solution.
Frequency controlled motorsare provided to adapt the conveyor speed to varying conveying capacities.Monitoring of the bucket filling level or control of thedrive unit form part of theequipment.

Wherever feeding of more than twoclinker silos or several mill hoppersin line is required, AUMUND Pivoting Pan Conveyors type SPBhave proved a reliable solution.With its intermediate dischargestations placed at any given position, the Pivoting Pan Conveyorensures multiple distribution ofvarious materials with just oneconveyor.
A pan reversing system integratedinto the drive and take-up stationallows for simultaneous materialconveying in the upper and lowerrun. The graphic shows the principle of the pan reversingsystem as well as specific feedingand discharge features. Depending
on given requirements, upper runfeeding can be performed by asimple feed chute whilst a two-waychute feeds the lower run. All feedchutes are equipped with overflowsystems for direct feeding of thesilos or hoppers during periodswhen the Pivoting Pan Conveyor is not in operation. The overflowchutes` operation principle is illustrated by the examples for clinker silo and mill hopper feeding.
Simultaneous conveying in theupper and lower run provides multiple solutions for materialhandling. For example, materialdischarged onto the upper run can subsequently be transferred
to the lower run through a discharge station located on the upper run.The material may then be distributed into clinker silos or mill hoppers through dischargestations on the lower run.
Separate conveying on the upperas well as the lower run is anotherpossibility. A hopper can thus beloaded with cement clinker by wayof the lower run, whilst for examplegypsum is conveyed on the upperrun. These are just two out of manysolutions available either for newplants or, in particular, for conversion or modernization in existing plants.

Standardized components and the varietyof applications make the Pivoting PanConveyor a versatile and reliable system.
The variety of applications and the related operations require perfectfunctioning of the individual componentssuch as the discharge stations and thepan and chain arrangement. The conveying elements of the Pivoting PanConveyor consist of 1 m long pans equipped with rollers at one end andwith a carrier axle at the other end. Thecarrier axle allowing the pan to performthe reversing movement is linked to bothchain strands. The graphic demonstrateshow the pans in the lower run are pulledby the carrier axle while being pushed in
the upper run. This arrangement enablesthe material discharge by lowering therails in the discharge station and by turning the pans in the drive and take-upstations.
With their slightly conical shape the pansoverlap by approx. 70 mm. This panarrangement with side boards of 150 or200 mm forms a tight material carryingsurface.
• Automated material distribution into silos or hoppers controlled by level sensors
• Customized layout and planning• Low energy consumption

For intermediate discharge into eithersilos or hoppers, the discharge stationsare of stationary design. Switching fromone discharge station to the other isperformed by a lever system loweringthe corresponding rail and actuated by a gear motor.The rail points setting is controlled by limit switches. The position of the rollers is monitored atany given moment to prevent their collision with the rails during the switching operations. The whole systemis PLC-controlled for smooth and safeoperation.
Feeding of long clinker storage hallsrequires continuous shifting of thedischarge point. Mobile discharge carriages which can be moved to anygiven position above the hall are usedwith this particular application. A capstan drive actuates the movement ofthe discharge carriage. If moved whileclinker is being conveyed, the clinker iscontinuously distributed over the wholetravel length of the carriage. A slotteddischarge opening in the storage hallroof is required over the carriage’s travel length. A roof-shaped rubber strip sealing minimizes dust emissionthrough the slotted opening. Sensors fitted to the conveyor supports monitorthe position of the discharge carriage.Level indicators control automatic shifting of the carriage as soon as amaximum filling level is reached insidethe storage hall.
The Pivoting Pan Conveyor is designedfor a multitude of applications.Theexamples shown provide information on technical modifications which havebeen repeatedly been carried out:
• Material feeding onto the lower run and distribution into different bins
• Material feeding onto the upper run, discharge onto the lower run and subsequent distribution into bins

• Material feeding onto the upper run and discharge onto the lower run followed by either bin feeding or material distribution over a defined area with the discharge carriage
• Material feeding onto the lower run and material distribution over a defined area of a clinker storagehall with the discharge carriage
• Material feeding onto the upper run, discharge onto the lower run and, when required, material distribution with the discharge carriage
• Material feeding onto the upper run and distribution into bins via discharge stations. At the same time conveying of a separate material loaded onto the lower run and distributed into a clinkerstorage hall with a discharge carriage
Further combinations are possible including upper and lower run conveyingas well as stationary and mobile designof the discharge stations. Our projectdepartment will be pleased to assist youin finding the appropriate layout for yourparticular needs.
Most outdated clinker storage halls are equipped with overhead travellingcranes to either distribute clinker in thehall in continuous operation or to feedthe mill hoppers. Also additives like gypsum and sand have to be conveyedto the respective mill hoppers. Thisapplication is best served with a PivotingPan Conveyor ensuring automated feeding of the mill hoppers and representing an economic and sensibleproject. The Pivoting Pan Conveyor andthe discharge stations are controlled bymaterial level sensors in the mill hoppersand ensure feeding on demand.
This operation mode is efficient andminimizes dust generation in the clinkerhall, thus providing improved workingconditions for the crane driver and allowing to comply with environmentalregulations.

Deep drawn pan conveyor type KZB 250
For clinker silo discharge with low dustemission, for proportional addition of low-burnt or foreign clinker AUMUND’s rangeof products includes gravity dischargesystems operating in combination with theDeep-Drawn Pan Conveyor type KZB 250.
The gravity discharge unit is designed to prevent the clinker from falling in anuncontrolled manner onto the pan conveyor. The material column on the panconveyor is reclaimed with low speed thusminimizing the generation of dust andavoiding dust filters. The gravity dischargesystems are provided with a shell valvewhich can either be operated manually orby means of a gear motor. As the height of the material layer on the pan conveyoris preset during commissioning, the discharge capacity and feeding onto the subsequent conveying equipment ismaintained at a fixed rate.
For maximum use of the stored volume,large clinker silos are equipped with amultitude of gravity discharge units. Themotorized discharge units are actuated by remote control to allow for automaticchange of the discharge points at regularintervals and uniform discharge of the stored material.
For automatic operation the pan conveyoris fitted with an ultrasonic sensor ensuringswitching from one silo discharge point toanother if the material flow is insufficient.Combined with the Deep-Drawn Pan Conveyor, the silo discharge systems are used in direct feeding of the mill hoppers. The 20 m curve radius and the28° inclination of the pan conveyor allowfor a layout with a direct conveying line,thus avoiding additional transfer points.
• Conveying from clinker silo to mill hopper with minimised dust generation
• No dust filters• Discharge capacities exceeding
750 t/h• More than 2,000 silo discharge

Clinker silo feeding with reversible pan conveyor
Reversible pan conveyor - functional principle
For special plant constellations, alternate conveying into two directions is required. Theappropriate solution for this application is theDeep-Drawn Pan Conveyor of special design:the reversible pan conveyor. By simply changingthe travel direction, alternate feeding of twoclinker silos is possible with just one conveyor.
This design developed by AUMUND is basedon a divided deep-drawn pan and half a chainpitch, i.e. 125 mm. By alternating a trough-shaped bottom plate with a cover plate to form the well-known deep-drawn pan with the 250 mm spacing, conveying is possible inboth directions. The illustration demonstratesthat the combination of one bottom plate and one cover plate each bolted onto the twocorresponding chain links is guided around thesprocket as a rigid unit. Always one cover platepoints in the requested conveying direction.This is achieved by defining the adequate center distance, which, for this reversible Deep-Drawn Pan Conveyor, comes up to a multipleof 250 mm plus 125 mm. This asymmetricalcenter distance ensures that the adequate turning point of the chain articulation matchesthe given conveying direction. With this arrangement the overlapping cover platesalways point in the chosen conveying direction.
For the reversible Deep-Drawn Pan Conveyor, ahorizontal arrangement is preferred. For largercenter distances a drive unit can be installedfor both sprockets.

AUMUND pan conveyors feature standardizedcomponents wich have proved reliable in practicaloperation for a thousand times. With the conceptof a modular system, components of differentpan conveyor types are interchangeable, a majoradvantage for spare parts management.
AUMUND pan conveyor tracks feature bogie-type rails complying with DIN/EN 5901/5902.The rail size ranging from S14 to S30 is chosenin accordance with the pan conveyor size. In thecurved area, the rollers are guided by upperguide-rails to prevent the conveying elementsfrom being lifted off the rails. The standard curveradius for Deep-Drawn Pan Conveyors is 20 mwhereas the curve radius for Bucket Apron Conveyors may be reduced to 8 m.
The standard roller design for AUMUND panconveyors features a tempered running surfaceand a sealing system preventing dust penetration.
Multiple metal sealing, a labyrinth seal and agrease chamber form part of the system and provide efficient protection against dustpenetration without the necessity of relubrication.AUMUND rollers are fitted with stub shafts connected to the roller bracket by a simplehexagon head screw for quick and easy dismantling.
The drive and tail shaft sprockets are equippedwith exchangeable toothed segments allowing to replace the sprocket segments even with the conveyor strand closed. The sprockets feature adouble tooth pitch and ensure meshing with thesprocket teeth only after each second turn. As aresult, the service life of the segments is twiceas long as with a single tooth pitch.
The standard chains of AUMUND pan conveyorsare listed in the table on page 9.
