4 The Samson Concept

The unique Samson wide belt designwith steel apron bar technologyoffers the strength of an apron feeder with clean operation.

The section through the Samsonbody shows the wide belt construc-tion with vertical hopper sides. Sincethe material depth is low comparedto the belt width virtually any bulkmaterial may be handled withoutrisk of bridging.

Trapezoidal apron bars support theload through to the conveyor chainrollers with the conveyor belt rive-ted above the steel apron bars toseal the load within the Samsonbody.

Since the conveyor chains are alwaysoutside the material flow chain wearis drastically reduced and inspectionmade easy.

Close contact flexible rubber sideseals mounted outside the loadedarea prevent side spillage even whenhandling granular and free flowingmaterials such as cement clinker.

In addition to the side seals the con-veyor belt has a raised edge to con-tain any dust particles passing themain seals. In the event of a totalseal failure any spilled material mayflow through the ventilated sidepressing clear of the return belt pre-venting damage to the conveyorchains and apron bars.

Optional ball or plain bearing chainrollers support the load reducingfrictional losses minimising powerconsumption.

Positive conveyor chain drive pre-vents slippage and allows high tor-que transmission within compactdimensions.The conveyor chainsystem eliminates belt tracking pro-blems and the need for any belt ten-sion to transmit the drive.

Robust construction designed toabsorb impact loads from tippingtrucks or loading shovels with gene-rous safety margins for long life andreliable operation.

A wide range of conveyor chainoptions are available from 380 to3200 kN. rupture strength selectedto suit each application.

5The Samson Solution

Traditional underground pit

The mobile Samson, shown with a flexible enclosure

Compared to a traditional under-ground pit for receiving bulkmaterials from trucks the Samsonoffers major advantages.

Flexibility:No excavation is required andonly the minimum of civil works,generally the Samson may be sim-ply bolted to a flat concrete slabfoundation. Since the Samson maybe installed completely aboveground maintenance access ismuch improved and housekeepingmade easy. Even for fixed installa-tions the Samson remains porta-ble since the unit may be easilyrelocated for future plant develop-ment and therefore investmentrisk is minimised.

Environmentally Friendly:The wide belt system allows fasttruck discharge with minimumdust generation since the materialis drawn from the truck body in acontrolled stream minimising par-ticulate separation, compared toconventional pits or hoppers thematerial fall is significantly reducedand as a result dust generation isminimised.

Mobility:For absolute flexibility the Samsonmay be fully mobile on pneumatictyres for use as a feeder in miningor port applications in conjuctionwith overland conveyors, mobilestackers and shiploaders.

Page 6: Samson Brochure

6 The Receiving Unit

Material is received to the Samson entry and drawninto the Samson body

Samson is fully loaded and the truck departs

The next truck discharges to the Samson

The Samson receiving unit may beused in applications where thedischarge rate may be controlled by asecondary feeder or conveyor system.

With the Samson empty material isreceived from the tipping truck directto the Samson entry and conveyedforward by the Samson belt.

When the first truck is emptied andthe Samson is fully loaded thematerial is discharged from theSamson head to theongoing conveyor orfeeder equipment.

As the next truckmanoeuvres intoposition ready totip the material iscontinually moved forward along theSamson body as the Samson dischar-ges leaving space at the entry.

The next truck then discharges to theempty Samson entry and the processis repeated.

In this manner the Samson dischargeson demand to the process systemusing a feeder or extractor conveyorto control the flow rate.

This system maybe used effectivelyto provide fasttruck unloadingwhilst allowing theon-going con-veyors to be sizedaccording to the process demandsthus minimising the cost and energyrequirements of the installation as awhole.

To regulate the Samson discharge alevel probe is required in the Samsonhead chute linked to the belt drivesystem to interrupt the discharge onthe high level signal, see page 21.

The receiving unit principle is idealfor applications where the truckdeliveries are infrequent and there-fore the Samson may be fully emptied between eachdelivery.

Alternatively, wherethe ongoing convey-ors may be of highcapacity allowing theSamson to bequickly discharged between loads.

Page 8: Samson Brochure

8 Controlled Rate Feeder

The Samson Feeder uses a level-ling blade at the discharge toregulate the material flow to theongoing conveyors providing aclosely controlled discharge rate.

In this manner the discharge rateis directly proportional to theSamson belt speed providing theideal solution where high handlingrates are required.

In addition, since the Samson con-veying rate is directly proportionalto the belt speed and bed depththe use of the levelling bladesystem permits an increased recei-ving rate.At the Samson entry thematerial bed depth is significantlygreater than at the discharge andtherefore the receiving rate is gre-ater than the discharge rate by aratio of typically up to 5 : 1.

For example if the ongoing con-veyors will handle 200 t.p.h. theSamson may receive at up to 1000t.p.h. allowing very fast truckdischarge...A receiving rate of1000 t.p.h. will unload a typical 30ton truck in less than 2 Minutes.

As the first truck tips and movesaway the second truck maymanoeuvre directly into position,during this operation the Samsonmoves the load forward rapidly toexpose the entry section ready totake the next truck load withminimum delay.The Samson provi-des a continuous regulated outputusing the buffer holding capacityto maintain the output betweentruck deliveries.

For really fast truck tipping with“Zero-Wait-Time” the high capa-city entry version as illustratedopposite allows the completetruck contents to be received wit-hin the Samson entry section.Typically in mining application thisarrangement may accept trucks upto 100 tons capacity with aSamson holding volume of up to300 tons of live material.

The design of the blade is criticalto both shear and lift the materialto avoid excessive load to theapron bars, conveyor chain anddrive system.

10 Storage and Pasteurisation

The Samson system provides theideal solution for the live storageof wet and sticky sludges down to20 % dry solids content.

Shown above the Samson storageunit with twin Samson receivingunits mounted outside the mainbuilding. Material is delivered fromthe receiving units to the storagesystem via a B&W belt conveyorsystem including a travellingplough unit to distribute thematerial along the full length ofthe Samson body.

To prevent material bridging in theSamson after prolonged storagethe tapered body section expan-ding towards the outlet to guaran-tee reliable discharge with theoption of negative angle side wallsfor extremely cohesive materials.

12 Body and Entry Designs

Two basic alternative designs areavailable using either a straight ordeflected chassis arrangement.

The straight pattern design is idealfor applications receiving from loa-ding shovels or where an increa-sed vehicle ramp is permitted fortruck loading applications.

The deflected chassis offersimproved holding capacity withthe minimum vehicle access rampheight and offers improved clea-rance where dissimilar materialsare handled without cross conta-mination.

Where free flowing materials arehandled the deflected chassisdesign allows the material to sta-bilise on the horizontal sectionbefore being elevated to thedischarge.

For applications where road truckonly deliveries are required thestandard parallel entry is the mosteconomical solution.

Where larger dump trucks areused or for loading shovel applica-tions where an increased capacityis required the flare entry is thepreferred solution.

The flared entry gives greatervehicle alignment tolerance offe-ring faster truck unloading andeasier vehicle manoeuvring forhigh capacity applications.

Combining the flared entry anddeflected chassis design significant-ly increases the entry volume tofurther reduce truck tipping time.

The flared entry is available invarious constructions using 6 mm,12 mm or 20 mm thick steel platesections to suit the working en-vironment.

Various standardised widths of fla-red entry are available, typically4.0, 4.5, 5.0 or 6.0 metres inwidth.

Optional stainless steel body panelconstruction for handling foodstuffs or aggressive materials.

13Under Floor Options

The wide belt Samson principleallows underfloor installation withthe absolute minimum of excava-tion handling even wet and stickymaterials without risk of bridging.

Drive Over Grill:For free flowing materials theSamson may be used with a grillabove allowing the truck to driveover, tip and continue forward inthe same direction avoiding theneed to reverse to the unit.Thisarrangement is ideal for high capa-city installations and may be incor-porated with a drive-over rampsystem for portable applications.For belly-dump trailers this is theonly effective solution..

Drive Over Platform:For cohesive materials (where agrill would block) the Samson maybe supplied with a hydraulicallyoperated drive over platformsystem incorporating an automaticsafety backstop.The vehicle drivesover the closed platform, whenthe vehicle passes the backstopand platform are raised automati-cally and the truck may reverse ashort distance to the backstop todischarge. In this manner theSamson belt is revealed belowwithout obstructions allowing freepassage of material from the truckto the Samson body.

Three units of this design are usedat the Rugby Cement Works forthe raw material reception - hand-ling clay, coal and coke each with aholding capacity of 50 tons.

Sub-Floor Installation:The installation shown here hand-les biomass fuels within a powergeneration plant and incorporatesa disc screening unit with aSamson sub-screen conveyorbelow.The primary Samson feederunit incorporates a levelling bladeto control the feed rate to thescreen.A total of twelve Samsonunits were used forming the mainraw materials reception facility forthe power station. In this applica-tion the wide belt Samson designoffered the ideal solution forhandling this wet and sticky mate-rial..

14 Dust and Fume Control

The unique receiving action of theSamson draws material from thetruck in a controlled stream andrequires the minimum of dustcontrol equipment.

For environmentally sensitiveapplications a range of enclosuresare available to contain any minordust generation within the Samsonbody.

The partial enclosure is generallyextended to the inclined sectiononly and provides control of dustgenerated at the discharge fromthe Samson to the ongoing con-veyor.

A full enclosure provides excellentdust control both at the tippingpoint and discharge and may beextended around the receivingsection for machines fitted with aflared entry.

Reverse Jet or shaker type dustfilters may be supplied, mountedto the enclosure roof, and provi-ded with an access platform formaintenance of the filter unit.

For most applications the profiledsteel enclosure is the preferredchoice offering a permanent solu-tion with good appearance andgenerally eliminates the need forany additional building enclosures.

For extremely sensitive applica-tions the enclosure may be exten-ded around the vehicle, forming atipping booth for absolute security.

The profiled steel system compri-ses a fabricated steel frame bolteddirect to the Samson side platesand clad externally in plastic coa-ted steel sheet with flashings andcappings to prevent rain ingress.

For temporary or mobile applica-tions the flexible PVC covers pro-vide a reasonable level of dustcontrol with minimum cost andweight.

In applications handling obnoxiousmaterials such as sewage sludgeodour control vents may be provi-ded for connection to a centrali-sed odour control system.

16 Head Chutes and Feeders

A comprehensive range ofdischarge chutes and feederequipment is available designedspecifically to suit the handlingcharacteristics of individual mate-rials.

Centralising Chutes may be usedwith reasonably free flowing mate-rials delivering to a conveyor eit-her in-line with the Samson or atan angle.

Parallel Chutes are ideal for hand-ling wet and sticky materials orwhere the ongoing conveyor orfeeder may be positioned at 90degrees to the Samson.

Various types of feeder systemmay be employed to suit therequirements of each applicationsas illustrated herein.

18 Drive Systems

The Samson drive comprises ashaft mounted gear unit as illu-strated with the option of a stan-dard worm gear for hydraulic dri-ves, a helical worm for electricdrives or for special applications aflange mounted helical/bevel gearmay be supplied.

Gear units may be installed singlyon either the left or right sides orfor very high performance applica-tions tandem hydraulic drives maybe fitted with a gear unit on eachside of the head shaft.

The Flender range of worm orhelical gears have been chosen fortheir robust construction and pro-ven long term reliability.

The Cooper split roller bearing isa high precision design with highload capacity.

The bearing is split into sectionsallowing simple installation andeasy replacement without distur-bing the main drive gear unit.

Direct coupled electricmotor drives:

As shown opposite the Samsonmay be provided with a conven-tional electric motor drive cou-pled to the main reduction gear.

This system may be used for appli-cations where the benefits of thehydraulic system are not requiredor for applications where hydrau-lic equipment in general is notpermitted.

Variable speed may be providedusing an Inverter unit or for closespeed control an eddy-currentcoupling (Task unit) is availablewith tachogenerator feedback toprovide precise regulation of thedischarge rate regardless of loadlevel.

The task unit system is particular-ly suited to the Samson since itprovides a wide speed range withconstant torque and a degree ofdrive protection using the integraltorque limiting system.

Hydraulic Drives:

For most applications the hydraulicdrive system is the preferred optionproviding automatic torque control

and soft starting with the ability tostop/start at high frequency usinga solenoid control valve to inter-rupt the drive to the Samson

conveyor.This isparticularlyimportant

when the Sam-son is used as

a receiving unit, see page 21 des-cribing the operation of the headchute probe in this application.

In the majority of applications theSamson will be subject to highimpact loads with the opportunityfor overloading, in these situationsthe hydraulic drive system absorbsthe drive shock and allows precisesetting of the drive torque to pre-vent damage to the driving gear inthe event of extreme overload.Load Sensing is an integral elementin the hydraulic drive, in the event ofhigh load levels within the Samsonbody the hydraulic pressure andflow are automatically regulated tokeep the power demand within pre-set limits preventing overload of themain electric motor/pump driveunit. Using this system the drivemotor may be sized to suit the nor-mal machine operation without fearof stalling in the event of short termoverload, thus minimising powerusage.The load sensing feature mayalso be used to regulate the Samsonoutput by automatically reducing thebelt speed as the load level increasesto maintain a partially regulateddischarge rate.All hydraulic systems include com-prehensive filtration equipment andprotection systems.The hydraulicrelief valve provides ultimate protec-tion for the drive and hydraulicequipment, this system reactsinstantaneously to extreme overloadsituations by limiting the torquetransmission capacity and thus pro-tecting the drive unit and conveyorchains.As a further benefit the hydraulicdrive system provides simple localspeed control by varying the flowrate to the hydraulic motor.Thissystem may be expanded to includean electrical interface allowing remo-te setting of the Samson dischargerate using a 4-20 m signal interface.

21Electrical Controls

The Samson is offered with arange of control options rangingfrom basic manual control to fullyautomatic unattended operation:

System 1

The entry level system comprisinga standard motor starter andIsolator mounted to a cabinet forthe control of the electric motoronly.

In this option the belt drivestart/stop is controlled only usingthe manual rotary speed controlvalve. Generally only applicable tomobile equipment where an ope-rator will be on station to controlthe machine manually. No instru-mentation interfaces are availablewith this option.

System 2

For applications where theSamson will be supplied with asolenoid valve to control the beltwith press buttons for beltstart/stop.

This equipment may be interfacedto the head chute level detectoronly, not suitable for other instru-mentation. Generally used forbasic fixed plant for infrequent usewhere a local operator will be onstation to control the machine.

System 3

A comprehensive system whichmay be used with the full range ofinstruments listed permittingautomatic unattended operationwith full interface connections tothe associated plant including volt-free connections to remote con-trol systems.

Switched Local and Remote con-trol options are provided plus sta-tus indication for all instrumenta-tion and drives.

This system may be further exten-ded to include a PLC with remotecommunication module to inter-face with the client’s main plantcontrol system.

Optional Electrical Control System

Probe Control Discharge

Using the receiving unit design the head chute probe or ultrasonic level detector isused to control the hydraulic drive solenoid operated control valve interrupting thedischarge of the Samson on the high level signal.

Typically the handling rate of the Samson will be significantly greater than the handlingrate of the feeder conveyor taking material from the head chute. In this situation theSamson will rapidly charge the head chute until the high level probe touches the mate-rial and restarts only after the material has left the probe for a timed period alwaysmaintaining a minimum level within the chute.With the ultrasonic system the Samsonstops on high level and restarts on the low level signal.

Using this system the empty Samson may receive at high speed not restricted by thecapacity of the ongoing conveyor system.
