Canning Conveyor has recentlysupplied an aggregate conveyingsystem for construction work on theredevelopment of Guernsey Airport.

With planning approval granted in October2011 the £80 million contract, which is part ofthe Guernsey Airport Redevelopment Project,predominately includes the rehabilitation andreconstruction of the existing airfield pavementsincluding the runway, apron and taxiways andthe installation of a new surface waterdrainage system.

Commenced in January 2012 the project willtake approximately 2 years to complete.

Bespoke System

The bespoke system which has been suppliedon hire was designed and manufactured byCanning Conveyor for the sole purpose ofconveying incoming aggregates from ships atGuernsey Docks.

Designed to accept 200tph of -20mmaggregates the system includes a conveyormounted receiving hopper fed from a bargemounted 360° grab. Mounted centrally thishopper feeds material onto a 16 metre long,ship to shore conveyor.

This conveyor incorporates many uniquefeatures that deal with the rise and fall of thetide. The tail end of the conveyor is fitted with apneumatic tyred wheel bogie which runs on thehatch cover of the ship; the head section beingmounted on a support trestle para-bolted to anew concrete pad on the sea wall. This supporttrestle is fitted with a slewing and pivotingarrangement which allows the conveyor to riseand fall at the tail end with the tide. A furtherfeature allows the tail to be lifted by the shipmounted grab and slewed around to rest onthe sea wall at times of high wind or gales.

All aggregate is delivered from this conveyor onto a 50 metre long groundconveyor which runs horizontally on the quay side which then feeds into areceiving hopper on a 12 metre long stockpile conveyor. This stockpile conveyorwhich elevates to a height of 4 metres discharges into waiting dump trucks, oralternatively stockpiling material onto the ground.

Canning SuperDrive™

The ground conveyor is powered by a Canning SuperDrive™ motorized 22kWsingle drive drum which is designed specifically to power ground conveyorsoperating in these applications, having the motor, gearbox and bearings totallyenclosed and hermetically sealed inside a steel shell drum.

With an impressive track record the Canning SuperDrive™ offers many benefitswhich include extremely low maintenance costs - (none, other than recommendedsynthetic oil change after 30,000 running hours) and a higher efficiency (97%)compared to approximately 85% on conventional drives.

The Canning SuperDrive™ single drive drum which provides a belt speed of 1.6metres/sec to the ground conveyor is fitted with ceramic lagging and includes ahigh tension bend pulley, jib discharge drum, loop bend drum and a primary andsecondary belt scraper. Complete with a discharge chute with integral crash boxand hinged inspection hatch the entire unit is mounted on a substantial skidmounted frame with cantilevered jib discharge.

Along with a loop take up unit, heavy duty tail end loading section the conveyorstructure is made up of Canning intermediate bays and Cannoflex beltingthroughout.

Designed and manufactured in the Canning workshops the system is providing aneffective and reliable system for the construction of the airport in the handling ofthe incoming aggregate for this huge project.

New transferchutes clampdown on coaldust at WestarEnergyThe largest electric utility in Kansas hasannounced completion of an upgradeprogram to redesign transfer chutes andload zones on the coal handlingconveyors at its biggest coal-fired facility,drastically reducing dust and spillage.Worn chutes and skirtboards at WestarEnergy's Jeffrey Energy Center (JEC)were replaced with custom-designedcomponents from Martin Engineering,employing special geometries thatcapture and concentrate the materialstream as it travels. The result is acleaner working environment, lessmaintenance and reduced waste, asmaterial is better contained.

Westar currently has 19 energy centers inKansas, providing 7,100 MW of generatingcapacity to serve more than 689,000customers. The firm employs about 2,400people and operates approximately 35,000miles of transmission and distribution lines.Situated on 10,500 acres of land, JEC is thelargest coal-fired power plant in the state, withthree generating units producing 1,857 MW.All three burn low-sulfur coal (as much as33,000 tons per day between them) and takeadvantage of some of the most advancedemission control technologies available.

Fugitive Material Challenge

Over time, operators at JEC began to noticeincreased dust and spillage around transferpoints on four of its 42-inch conveyors. Theproblem was traced to worn chutes andskirtboard liners, which no longer containedthe coal fines as they did when new. A worn-out skirtboard liner plate was found to beexacerbating the problem.

“We have two transfer buildings where theyard feeders deliver incoming material tosupply the boilers,” explained Coal HandlingEngineer Josh Olson. “They were wearing out,and we knew we needed to take action. Butrather than patching the existing chutes andliners, we wanted to see if we could find abetter design solution.”

The 1/2 inch thick belts on conveyors 101A,101B, 301A and 310B travel 550 FPM andhave a capacity of approximately 1,000 tonsper hour. The load is 4" minus PRB coal, withmoisture content around 28-30% and bulkdensity of 45-55 pounds per cubic foot.

Westar contacted Martin Engineering to investigate its options, andtechnicians came out to assess the situation. “Chute design has evolvedsince this system was first installed,” observed Martin EngineeringTerritory Manager Jason Illum. “Today's transfer point chutes capture andconcentrate the material stream as it travels through the chute. Each oneof our designs is tailored to suit the specific material characteristics andconveyor systems of the individual customer, rather than using stockproducts and attempting to make them work,” he explained.

Before proceeding, Westar engineers visited a nearby facility in whichMartin Engineering had installed a similar system. “We were veryimpressed by what we saw,” Olson continued. “The conveyors deliveredexcellent belt support, and the material flow was directed to minimizeturbulence and maximize dust containment.” Transfer Chutes from MartinEngineering provide the dual benefits of minimizing aeration andpreventing buildup within the chute, particularly important when dealingwith combustible materials.

To achieve the optimum chute, spoon and settling area, engineers used3-D computer-based flow and modeling to define the geometry. MartinEngineering included detailed information about the specific materialcharacteristics and the physical parameters of the conveyor itself, such asthe feed system, belt properties, support structure and transfer distances.

The transfer chutes built for the Westar facilityemploy a “chute and spoon” design, with thehead discharge chute at the top of the systemand a spoon receiving chute to place materialwith minimal impact onto the belt beingloaded. “The head chute design allowed forexternal mounting of the head pulley bearings,replacing the old design,” Illum said. “Thespoon provides a curved loading chute for asmooth line of descent, consistently feeding thematerial at a specific speed and direction tominimize impact in the loading zone.” All fourtransfer points also received MartinEngineering belt cleaners to minimizecarryback.

“One of the features that our operators and mechanics really like is theadjustable skirtboard,” Olson said. “We can get very precise sealing,and the reversible design of the apron seal gives us double the servicelife. When one side wears out, we can just flip it over. It may seem likea simple idea, but it shows that Martin is ahead of the curve with itsproducts.”

Martin® ApronSeal™ Skirting was the first dual-sealing system on themarket, incorporating a primary seal clamped to the steel skirtboard tokeep lumps on the belt and a secondary or “outrigger” strip to captureany fines or dust particles that pass beneath the primary seal. Thesecondary seal lies gently on the belt and self-adjusts to maintainconsistent strip-to-belt pressure, despite high-speed material movementand fluctuations in the belt's line of travel.

“Another deciding factor for us was the no-excuses guarantee,” Olsonadded. “We didn't want to have to spend a lot of time tweaking thesystem. The Martin Engineering guys are extremely knowledgeable, andthey've been out several times to make sure everything is running at itsoptimum level.”

Since the transfer chute overhaul was completed in 2011, results havebeen excellent. “We don't take specific measurements or airborne dustreadings, but we can definitely tell that the load is centered, spillage issignificantly reduced and dust is being contained,” Olson concluded.Quarterly inspections and reports are provided by Martin Engineering forone year at no cost to JEC.

VEGA measurebiomass levels atDrax PowerDrax Power Station in North Yorkshireis already the largest, cleanest and mostefficient coal-fired power station in thecountry.

Already home to the largest biomass co-firing facility in the world commissioned in2010, in which sustainable biomass isburnt alongside coal to produce electricity,Drax has ambitions to become apredominantly biomass fuelled generator.Not only does their investment in biomassco-firing strengthen their environmentalleadership position, but it further enhancestheir reputation to stay at the forefront ofdevelopments to establish effectivealternative fuel technologies for electricitygeneration in the UK. Electricity generationfrom biomass is a low carbon technologydelivering significant carbon dioxidesavings compared to fossil fuel generation.

The biomass co-firing facility enables thepower station to receive, handle, store andprocess a variety of biomass materials.These are directly injected into Drax's coal-fired boilers where they are burnt alongsidecoal. The storage facility for the biomass isa key part of this process, to ensure it iskept at optimum condition before beingused.

When compared to coal, biomass is lighter,it has fluctuating handling properties andgenerally much lower, variable bulk density.It therefore requires larger storage facilitiesand offers some different processchallenges. The feedstock products varyfrom forestry residues, or cultivatedproducts such as Miscanthus and Willow, toagricultural by-products like straw. Thestorage capacities for these products needto be large and stock rotation/retentiontime requires careful management, as theproducts need regular 'rotation' to avoidany degradation. The construction of thesilos can also differ greatly, with tallernarrower and shorter wider designs,depending on material behaviour andmaterials handling schemes.

However, even with large silo sizes, the biomass typically only has aretention time of only 24-48hrs, before being sent to electricityproduction.

An important area of this fuel stock management is the levelmeasurement. A non-contact technology is preferred on site, tomitigate the potential for fouling and wear. VEGA have installedmany non-contact radar level transmitters on biomass levelmeasurement around the world, where they have a provenperformance dealing with dust and filling noise. At Drax, there aretwo 12,000m3 storage silos, around 27m high and 30m indiameter, and the biomass is brought in by rail. These are centrallyfilled by conveyor and emptied via rotary screw discharger at thebottom. The size and throughput means the silos are being frequentlyfed into and discharged from giving an uneven product surface andthe need for long range measurement.

VEGA have installed non-contact VEGAPULS 68 level radars forsolids, working over a range of approximately 27m. Two units areinstalled on each of these large silos, to give an average reading, aswell as for dual redundancy level measurement of the biomassmaterial. They are mounted towards the centre of the silo, aimeddown and slightly outwards, this is to measure at a pointapproximately at half the radius, to deliver a good average levelreading over the surface profile. Although the conveyor fills point isquite close-by, the units work reliably, regardless of the filling stream.There are no cross-talk issues with VEGAPULS radars, even withmultiple units in the same silo. This is achieved using dedicated pulsesampling filters, which means there can be many in the same areawith no danger of them picking up each other's signals. The unitshave worked reliably ever since their installation over two yearsago, providing information to facilitate the available filling capacityfor the rail transport department and feed stock supply data to thepower station control room, optimising the biomass supply to Drax.

The multi million pound co-firing facility provides Drax with thecapability to produce 12.5% of power generation from biomass co-firing and it is a key element of their goal to reduce carbon dioxide(CO2) emissions.

Achieving energy efficiency from motors and drive systems for conveyors andelevators requires the specification of gearboxes, drive motors, couplings andchains that are capable of withstanding extreme loads, shock, andcontamination from dust, debris and glass, plus widely varying temperatures.The quest to maximise efficiency is more than worthwhile; by focussing uponefficiency and cost reduction, the quarrying, mining and constructionindustries will be far better placed to survive the tough economy and maintaina strong competitive advantage.

To extract raw materials from the ground in the most cost effective wayrequires an awareness of the most up-to-date methods of production, state-of-the-art products and new technologies. Companies such as ERIKS, that offera deep and broad experience across the engineering industry, understandthe challenges presented by harsh environments and work constantly todeliver solutions that meets those needs, with energy-saving features built in asstandard.

The addition of one particular component offers not only the potential to saveenergy but reduces shock loading to machinery, and provides continuousmotor protection, minimising both maintenance and operating costs.

That component is the Fenner QD Inverter.

This capability of this device to vary the speed of an electric motor deliverssignificant energy- and cost-savings, especially in industries where machinerycan be required to work more or less around the clock. When inverters arefitted to heavy duty machinery, the resulting elimination of shock loads cansignificantly limit wear and tear as well as reduce energy consumption.

Efficiency is also enhanced by upgrading to an IE3 motor, which offers evengreater energy efficiency than the IE2-rated motor now required within theEU. The ERIKS Online TCO Calculator provides a simple method ofevaluating a motor upgrade, enabling the user to view the total cost ofownership for the year, or for fifteen years, or any period of years inbetween. The results provided by the calculator will list and compare thecost of repairing and running the existing motor, replacing it with a standardIE2 motor, or replacing it with an energy-efficient IE3 motor.

Plant reliability is vitally important in minimising downtime and maximisinguptime - even a couple of hours' downtime can result in huge losses - but arange of simple but highly effective tools are now available that can reinforcethat reliability.

Vibratory conveyorsand feeders fromMogensenMogensen manufactures an extensive range ofvibratory conveyors and feeders.

The designs, based on more than 60 years ofexperience in the field of vibration engineering, extendfrom light-duty, stainless steel units for use in theprocessing of foodstuffs and pharmaceuticals up to theheavy-duty, heat-resistant machines used, for instance, infoundries and incinerator plants. Trough conveyors areusually custom-made to suit individual applications andare powered by twin Invicta rotary electric vibrators.They are available in either open or fully dust-proofedversions with or without wear-or heat- resistant liners.The company also offers tubular, vibratory conveyors ineither mild- or stainless-steel execution. Internaldiameters range from 200mm to 609mm; lengths varyfrom 2 to 6 metres between inlet and outlet centres.These versatile, inherently dust-tight machines may belinked together using flexible, dust-proof connectors,either in a straight line or angled to fit plant layoutneeds. They are also driven by twin Invicta vibratormotors, and, together with Invicta electronic variablespeed controllers, can deliver easily adjustable feedrates. Throughput capacities extend from a fewkilograms per hour up to 300tph (based on a bulkdensity of 1.6 tonnes/m3).

The Mogensen vibratory feeder range starts with thesimple, inexpensive Type SR1 machine, which is drivenby a single, rear-mounted Invicta vibrator motor. Troughwidths up to 1000mm are available and offercapacities up to 160tph depending on the bulk densityof the feed material. The heavier Type TR1 feeders aredriven by twin rear-mounted Invicta vibrators and aresuitable for variable speed control. Trough widthsextend up to 1000mm; throughput capacities reachabout 300tph depending on the size of machine andthe feed bulk density. The feeder range also includesthe heavy-duty Type TS machines, which are availablein three different construction weights and trough widthsup to 2.5m. Capacities are up to about 800tph. Thesemachines are driven by two side-mounted Invictavibrators, and are also suitable for variable speedoperation. Of particular note are Mogensen's spreaderfeeders, which accept a flow of material from arelatively narrow source and distribute it evenly across awider item of process equipment. Spreads of up to 3metres are possible. Machines, which spread a narrowfeed efficiently and evenly across two or more followingmachines, are also available.

Replaceable stainless-steel, rubber, hard metal, ceramicand adhesion-resistant liners are available for allfeeders and conveyors. Some models of machine areavailable with heated bases for the non-stick handlingof damp clays and damp, fine stone.

Pack your bagsand goThe number of industrial processesthat ultimately dispense an endproduct into a receptacle (sachet,stick pack, bag, sack, or big bags) isextremely large and the spread ofapplications span virtually allindustrial sectors. The diversity ofproducts (ranging from very finecohesive powders to free-flowinggraded aggregates) being packedprior to shipment to end users isenormous, and consequently therange of dispensing equipment hasgrown over the years to meet thisseemingly ever expanding industrialrequirement.

One of the prime requirements for anydispensing equipment is that the fillingoperation should be undertaken withminimum overfill, maximum consistency(between filling operations), and of coursewith as little spillage or fugitive particlesgenerated as possible. Modern controlsystems have proven invaluable for the co-ordination and operation of high speedfilling operations, but even the bestinstrumentation or supervisory control anddata acquisition (SCADA) control can onlygive optimal results if the bulk particulatebeing handled can be brought to thepoint of entry into the receptacle in acontrolled bulk condition and at acontrollable flow rate. Failure to achievethese seemingly basic requirements forparticulate delivery can bringconsiderable inefficiency and degradationto local environmental working conditions,through poor filling efficiency and spillagedue to powders “flooding” from handlingequipment.

For some companies (often thoseprocessing easily aeratable - or more tothe point air retentive powders),maintaining shift output levels can be analmost daily battle. In many cases thecause of the problems can be traced backeither to the use of buffer hoppers thatafford minimal residence time for powderto densify before reaching the meteringapparatus or to an overly exuberantapplication of aeration to obtain a“consistent” feed of material (the onlyconsistent thing about some of thesesystems being their inherent inconsistency)!

Approaches to resolve such fill variationproblems should invariably focus on anevaluation of the flow properties of thepowders being handled. As a generalobservation most concessions to the need

Product focus


for a standard piece of equipment to handle cohesive powders invariableinvolve the attachment of additional aeration points or vibrators (usuallypositioned in the most convenient point for access - rather than for optimalassistance to flow). Such air introduction points can be of benefit, butshould be considered as an augmentation to best practice for reliableflow, taking second place to a consideration of bin geometry and flowcontrol operation. The latter two aspects of equipment should bedesigned in accordance to the flow behaviour of the powder - withaeration (in very small quantities) being used to assist flow. The control ofair usage to initiate flow is an aspect of operation that can bring veryrapid and tangible benefits to plant optimization where packing problemsoccur with fine powders.

In summary, although control systems and automated operations haveadvanced considerably over the last decade it is often the case that thepotential for realizing the full potential of such systems is often hamperedby poor flow performance when fine powders enter the equation. Themain reason for this under-performance is invariably a lack ofunderstanding of the importance of correct bin and interface design forthe powders being handled.

Saxlundinnovationsdeliver on RWEnpower plantcontract


Scotland's mega renewable plantbiomass combined heat and powerplant (CHP) at Markinch incorporatesSaxlund efficiency know-how andequipment in turnkey projectmanagement and supply contract

Evidence of Saxlund International'scapability to tackle large scale projectsand deliver innovative solutions isspotlighted by its prestigious contract forthe RWE npower renewables biomasscombined heat and power plant (CHP) atMarkinch in Fife. The bulk handling andbiomass experts were tasked with projectmanaging the Biomass Fuel HandlingSystem for the £200 million build in 2010which, when finished in 2013, will be thelargest of its kind in Scotland.

The Biomass CHP, which lies on thegrounds of Tullis Russell Paper Makers, willreplace their existing coal fired powerplant and reinforces the company'sposition as one of the world's leadingenvironmentally-focused papermakers.Using a mixture of reclaimed and virginwoods, the 49.9 megawatt plant willsupply both steam and electricity to TullisRussell. Moreover, the company alsosigned a 20 year energy supply contractwith RWE npower renewables, with anyexcess electricity created being supplied tothe National Grid, equating to around25MW an hour, compared with the17MW actually used.

View of the three

concrete storage silos



To help complete this massive project,Saxlund had to choose and develop keysubcontractors, as its managing directorMatt Drew explains: “One of the largestchallenges to overcome was the removal ofoversized materials. Our solution was to usetwo large disc screen separators, which arecapable of screening up to 780m3/hr ofwaste or virgin wood before conveyingthem to our storage silos. We then had toerect three 20m diameter, 26m highconcrete storage silos, complete withexplosion protection. Each Silo is fed bytwo overhead conveyors from the receptionsystem.

“The process of discharging the wood fromthe silos is completed with the use of aSaxlund TubeFeeder®. Each TubeFeeder sitson the bottom of the Silo and sweeps itsfloors discharging the wood at a rate of upto 285m3/hr. The patented TubeFeeder®

consists of a screw conveyor housed insidea rotating tube. The tube is perforated witha regular slot pattern permitting 'activated'material to fall onto the screw conveyor,thereby eliminating the external staticmaterial pressure on the screw andpresenting a uniform feed to the screw.”

Here Saxlund has been able to aid TullisRussell's eco drive, with this system needingjust 25% of the power needed for traditionalexposed screw reclaimers. The biomassmaterials collected by the TubeFeeders aretransported by chain conveyors back abovethe ground where they discharge into thedownstream conveying system.

Other innovations to support the substantiallogistics operation at the plant includespecification of Lorry Reception units. Eachof the four units is capable of receiving upto 380m3/hr from either Walking FloorTrailers or Tipping Trucks. The units aresupplied complete with reverse jet bag filtersto minimise dust emissions and fully mobileenabling a simple robust method ofproviding redundancy.

Working with Canning Conveyors to deliverthis project, due to the large size of the FuelHandling System, Saxlund and CanningConveyors negotiated separate contractswith the client for their respective scope ofsupply, with Saxlund taking the overallProject Manager role.

“This is a challenging project, whichdemands innovation and creative solutionsat every stage. Ultimately its projects of thistype, not just because of the scale, thatallow us to demonstrate how we can addreal value to the project; we believe thatTullis Russell is a prime example,” concludesMatt.

Simply callJansen to extend the height of your existingwalls or to add more storage boxes.Moving to another site? You can moveyour blocks with you and construct themagain at the new site. With Legioblock®, itis all possible. Also, while many localauthorities regard a Legioblock®

construction as 'temporary structures',planning consent is much easier to acquire,in some cases not even needed at all.

The standard size of a Legioblock® is 160x 80 x 80 cm with a weight of 2.400 kg.Thanks to the interlocking principle, theblocks are easily stacked an placed,without the need of any fixing material.

This way, walls can be built in minutes andhours as opposed to days or weeks.Legioblocks® are delivered directly fromstock, which means very short deliverylead times. They arrive on the back oftrucks and are then lifted into place with atruck mounted crane very similar to a brick-grab.

Flexiblestorage forbulk materials



Main applications of Legioblocks® are storage bays, retaining walls,partition walls, soundproof walls, fire resistant walls and industrialworkspaces. Especially for waste recyclers and other companies that dealwith bulk materials, it is the ideal solution to - temporarily or permanently -optimize storage capacity. Legioblock® walls also have excellent sound-proofing and fire resistant properties.

Legioblock® is a product of A. Jansen B.V., a Dutch based company withover 15 years of experience with concrete building blocks. Over the years,the Legioblock® has developed as a high quality product and has become avery popular solution in Northern Europe for all kind of constructions. Theultimate flexibility and the sheer durability of blocks, make it a highly cost-effective construction system.




Schenck Processexpertise inpneumaticconveyingThe combined product andprocess technologies fromSchenck Process areable to handle awide variety ofraw andprocessedmaterials fromdelivery todespatch.

The market-leadingpneumaticconveyingtechnologyprovidessystems that efficientlyhandle bulk materialswithin a productionplant with very high levels of reliabilityand minimal plant downtime.

By using Dense Phase pneumaticconveying, difficult materials that areabrasive or friable are transported in aplug form at very low velocities whichensures minimal wear on the pipes andbends and a long life of the installation.Standard Schenck Process systems areavailable for material temperatures up to450° C, flow rates of over 300 tonnes perhour and for distances up to 2.4km,depending upon the material, all in asingle pipeline.

Central to the operating efficiency of allSchenck Process pneumatic conveyingsystems is the Dome Valve® whichincorporates a unique and highly reliableinflatable sealing arrangement. Theinherent simplicity of the Dome Valve®,the only moving part in system, ensures theoverall system's reliability and lowmaintenance operation. The originalDome Valve® was developed by ClydeMaterials Handling in 1974 and theCompany was purchased by SchenckProcess in 2011 and the Dome Valve® ispart of the extensive range of SchenckProcess technologies.

Schenck Process pneumatic conveyingtechnology ensure that materials aremoved without creating any dust tomaintain a clean working environmentboth internally and externally to the plantwhich has significant operating benefitscompared to alternative conveyingmethods.

Phase 3 completed atGrain Storage FacilityGAME Engineering has been working with WoldGrain since2010 completing Phase 1, Phase 2 and now Phase 3 of theirplant development programme at their grain storage facilityin Hemswell, Lincolnshire.

As part of WoldGrain's planned programme of works which includeda plant upgrade and throughputs in 2012, they installed new in-feedconveyors to their original storage silos.

The new conveyors have increased the transfer capacity from 50 t.p.hto 100 t.p.h to match the equipment installed during phase 1 & 2.

This investment will not only increase the transfer throughout but alsoeliminate the untimely breakdown which can happen due to thepressure put on the old equipment by the earlier phase improvements.

It is hoped that during 2013 further improvements can be made to theold silo discharge arrangement so that their routes become morereliable and faster.

GAME Engineering Ltd has been working in the Grain & Seed sectorsince its formation in 1986, originally focussing on the design,manufacture and installation of milling equipment.

Specialising in these sectors, GAME has amassed a wealth ofknowledge, experience and capabilities which have beenimplemented into a variety of projects already undertaken.

The expertise that GAME hold in turnkey solutions and CAD Design,means they can offer services to design, construct, upgrade, refurbish,extend or improve processing facilities






Guttridgeconveyorsdeliver highreliability forabrasive dutiesin new Lafargeaggregateblending unitGuttridge Ltd, a leadingmanufacturer of materials handlingsolutions, has supplied a suite ofconveying equipment to the LafargeBarnstone Works (NottinghamshireUK) for feed and product transportthrough a new aggregate blendingunit. Specified to ensure maximumreliability for highly abrasive processstreams, the six Hi-Load bucketelevators and the Kleenbelt beltconveyor incorporate sensors forupset detection as well as a numberof features that streamlinemaintenance. Lafarge is a globalleader in the production of buildingmaterials and has installed the newplant to makesand/cement/aggregate blends forspecific applications within theconstruction industry.

“We already had Guttridge machinesworking reliably on site,” explainsAdam Elmes, Project Manager forLafarge, “so we were well aware thatthe company could provide us withquality systems at an acceptable price.Beyond that, though, we wereimpressed with the company'swillingness to innovate new solutionsthat would help us to achieve the veryhighest levels of reliability - a majorgoal for our site. The Guttridgeengineers are both responsive andknowledgeable and this was animportant factor in ensuring the successof the project.”

process. The belt conveyor is a completely enclosed system thattransports a cement and sand mixture some distance, from avibratory screen to the elevator feeding the mixer. All equipmentwas supplied with a host of carefully engineered features designedto ensure reliable long-term abrasives handling with minimalmanual attention, as well as to ease maintenance.

“All the systems came on stream quickly and easily and areworking well,” continues Mr Elmes, “but we're especiallyimpressed with the Kleenbelt. It's a really robust design with anexcellent sealing system. All of the incoming material is fed cleanlyonto the belt without spillage and we have complete productcontainment even though the stream is very dusty. This is a majorimprovement compared with our previous experience of aconventional belt conveyor.”

The Kleenbelt conveyor is a unique but well-proven solution forapplications where it is especially important to avoid productspillage or emission. Capable of handling flow rate up to 800cu.m/hr it is suitable for the widest range of materials - from rolledoats to rubber crumb, coal to cement.
