    This is how you get it out

    AMB is specialised in plant- and machinery engi-neering for the disposal industry. And here onething is valid: Every task needs a specific solution.

    Our products provide a solution which offers ourcustomers a maximum amount of use, reliabilityand efficiency.

    No matter if it is a new processing plant or theoptimisation of existing plant technique, everyAMB plant is planned individually.

    Our experienced project engineers not only workout the plant design, but will also be available forsupport during production and installation, untilthe entry into service takes place successfully.

    There’s a lot in it

    As varied as the demands of prepara-tion and sorting can be, as different arethe allegations for the realisation of eachplant. Planning and projecting by AMBis always accomplished in narrow coope-ration with our customers.

  • Pre shredders ENGINEERING 07

    Each tool shaft is equipped with a planetary gear and ahydraulic adjusting motor. The drive is connected with aPLC control, which has pre-selectable programs, that arespecifically (and regarding the type of waste) optimised.

    When shredding with a fixed middle comb, the tools areinserted against each other in rugged tool shells. In nor-mal operating mode the shredding is done on the middlecomb, in the reversing mode on the side combs.

    When a rotating comb shaft is used, both shafts rotatecontrary in normal operation mode, but with differentspeeds. The shaft with the lower speed then has thesame role as the middle comb. In the reversing modeshredding is done on the side combs, too.

    Massive contraries, which could cause blocking of themachine, can be removed mostly automatic by an dis-turbance material exit on the side.

    How they workThe speciality of all AMB two shaft shredders is the re-versing process of the individually driven shafts, which iscontrolled by a PLC. During an idle run or when the loadlimit is reached, one or even both shafts switch theirrotational direction and continue working in opposition.

    How they workBelow the hopper a hydraulic pusher unit feeds the in-put to the rotor, which is equipped with block blades. Therotor shreds the material against a solid stator blade andalso moves the material in a rotary movement. A sievebasket under the rotor defines the grain size of the output.The sieve unit can be pivoted hydraulically, so it can bechanged easily and allows quick access to the rotor andthe tools. The drive is connected to a PLC control, whichhas automatic programs optimised for specific kinds ofwaste. Alternative to this the pusher and the rotor can becontrolled manually. The screwed block blades, made ofa special tool steel, can be used up to four times and arefixed with separate blade holders.

    Homogenising drums

    Stationary homogenising drums mix pre-treated waste types and prepare them forthe following biological treatment.

    Different sizes allow the individual adap-tation to optimise the throughput and thematerial stays in the machine.

    Solid and generously designed drives pro-vide high availability even at low rotationspeeds. The feeding with a spiral conveyorprovides a mostly closed drum entry, whichimproves the addition of sewage sludge orseeping water.

    Stationary drum sieve machines separate theinput volume flow into different output fractions.The project-specific specifications, like kind ofwaste, throughput and sieve grain define thetype and size of AMB drum sieve machines. Theproduct range spreads from one-piece drumbodies with one or more mesh apertures todrum bodies in a solid frame construction withchangeable sieve plates.

    Solid steel plate housings with big serviceopenings, closed chutes and connections fordust exhaust reduce the dust- and noise-levelto a minimum.

    The light and areal fraction mainly consists of paper, plasticfoils, textiles, cardboard etc., while the heavy and roundfraction mostly consists of metals, stones, wood, rubber,plastic bottles, glass etc..

    The mesh aperture of the sieve tub has changeable sieveplates, which make it possible to separate additional ma-terial in a selectable grain size as a fine fraction.

    · two drive shafts with one motor each, controlledby frequency converter

    · steel plate housing with big service openings andconnections for dust exhaust

    · air support to enhance the ballistic separationprocess

    How they workThe pre-treated input material is fed in the middleof a inclined sieve tub, which rotates circularlyaround two eccentric shafts. The drive consists oftwo electric motors, which have a common frequen-cy converter to achieve synchronism. The motorsand the bearings of the shafts are positioned out-side of the waste flow, so that the minimised dustload extends the maintenance intervals and there-fore the maintenance costs.

    Multi fraction separators

    By the rotation around the shafts a jolting effectis generated, that, with the adjustable, inclinedsieve tub and because of the different physicalattributes of the single waste materials, getsthe pieces to move in different ways. Light andareal pieces go up in movement direction, heavyand round pieces go down against the move-ment direction.

  • 11Conveyor technology ENGINEERING

    Chain-guided conveyors have a very sturdy construction,in which the belt is moved by a fixed connection betweensupport ledges and chain, which runs over chain wheels.In the drum-guided conveyor, the tensed belt runs over adrive- and a redirection drum.

    Years of experience led AMB to an own proved modulesystem. Target is a low vulnerability to failures and there-fore a high availability of the whole plant. At the same timethe modular construction with mostly standardised andscrewed elements provides a high flexibility for comingupgrades or rebuilding. Main feature here is a closed sup-port frame in different construction heights with openingsfor service purposes.

    Drive- and redirection segments with their tense stationare adapted in different lengths, just like the height of thematerial guiding ledges and the side sealing of the belt.

    The target of AMB is to provide the matching conveyortechnology for every kind of waste.

    Feeding conveyor as plate belt conveyor

    The conveyor technology,developed and produced byAMB, is designed speciallyfor the function of transpor-ting different kinds of waste:

    · residual waste like house-hold- and bulky waste

    · mixed waste like industrialwaste and recycling wood

    · waste from separatecollections like lightpackages, pasteboardpaper, cardboard, biowaste or compost

    These heterogeneous wastesmake high demands of theconveyor technology, whichmust provide different basicfunctions:

    · feeding conveyors, underand over floor

    · conveyor, upward conveyor,sorting conveyor etc.

    Technically, this demandscan be realised with differ-ent types:

    · chain-guided conveyorslike roller chain conveyorsor plate belt conveyors

    · drum-guided conveyors likesliding-bottom conveyor andcarrying roller conveyor

    Chain-guided and drum-guided conveyor

  • AMB offers to the customers of the disposal industryextensive performances starting with the planningand projecting up to the realisation of the wholeplant.

    The mechanical treatment concentrates on thedevelopment and assembling of the core compon-ents of sorting and treatment plants like grindingmachines, separating and mixing technology, aswell as conveying technology, steel constructionand PLC-control. At the biological procedure plantengineering for aerobic and anaerobic wastetreatment are the focus point.

    A wide range of references in Europe underlinethe competences of AMB in building sorting andtreatment plants today and in the future, flexibleand economical in a way that makes it possibleto making the best of the rest.

    NIR-separators with a combined material and colouridentification guarantee a high sorting quality. Thepurity is achieved by a cascaded sorting chain of posi-tive and negative sorting of the desired fractions. Theoptimation of the profit can be realized by purificationof the residual streams.

    The target fractions are controlled finally by hand inorder to extract non-beverage-bottles and other partsof the same material.

    In the first processing step large pieces of cardboard,foil, non-packaging made of similar materials and largedisturbance materials are removed in the pre-sortingstep. Separating technology like drum sieve machinesand multi fraction separators separate the input volumeflow into various fractions.

    In additional processing stages recyclables like ferrousand aluminium can be separated by using fe- and nf-separators. For the light film fraction air separationsystems are appointed.

    Visual identification systems with an automatic dis-charge perform the separation of fractions like be-verage packages, paper, films and different kinds ofplastic like PET, HDPE, PS and PP.

    The final quality control takes place as an manual con-trol. Varietal recyclables are pressed to bales and thenbrought to the reprocessing.

    In preceding sorting plants light materials are separatedin that way that the material stream plastic bottles is al-ready enriched on a high level with the target fractionsPET-clear, PET-light blue, PET green and PET.

    A combination of machinery for perforation and screeningas well as conveying technology for equalization and iso-lation optimizes the presentation of the material streamsat the visual separation system.

    The charging of the material occurs according to the col-lection principle by back openers or sub-corridor feeders.The essential sorting consists of an combination of suc-cessive turned mechanical processes and manual controlsin succession.

    Industrial waste

    If the target is an efficient sorting, mixed constructionand industrial waste or bulky waste have highrequirements at the plant manufacturing.

    A process combination of grinding, separating andconveying technology have to comply the demandingtask to separate the material streams.

    Downstream visual identifying systems divide full-automa-tically the different recyclables. On a high level of through-put economical output in combination with high puritiescan be realized. The manual follow-up control for the quali-ty assurance takes place after the upstream mechanicaltreatment. Intermediate goods like parts of the fine andresidual fraction or high caloric fraction provide the op-portunity of different uses. All recyclables (pressed intobales or stored in containers) can be put on the market.

    Even if the separate collection of pasteboard, paper andcardboard builds the base for an high recycling quote, onlythe right choice of technology can lead to an economicalsorting plant. Main part here is a automatization as far aspossible.

    Mechanical separating technology split different materialstreams. Conveyor technology straightens out and isolatesthem, so that a visual identification can guarantee an va-rietal separation in defined raw material sorts. In additionto the main product deinking, there are mixed paper andvarietal brown and white cardboard.

    Prior to the final bundling for the ongoing marketing, allqualities are controlled again manually.

    15Treatment plants PLANT ENGINEERING

    The main motivation of residual waste treatment withbiological processes is based in the “EU-landfill direc-tive”. The target is a reduction of the residual wastevolumes to be land filled – especially a reduction ofbiodegradable contingents. To transfer the resultantdefaults efficient in the plant construction means totreat the residual mechanical on multi-stage. With theright mechanics as a combination of grinding, convey-ing, separating and mixing technology the fine fraction(mainly organic material) is separated for the followingbiological treatment.

    The biology can be done in an aerobic way (composting)or in an anaerobic way (fermentation) or as a combina-tion of both.

    Mechanical-biological residual waste treatment

    Mechanical treatment in a MBT

    The anaerobic biological processes for the treat-ment of residual waste can be performed as a wetor dry process. Generally the aerobic treatment asa one- or two-step process follows the fermentationtechnology.

    AMB now puts the focus on a concept for biologi-cal treatment that is based on the principle of wetfermentation with following wet oxidation. The ob-jectives and tasks are always defined specificallyfor each project. But the central point of theseprocess conception is the production of biogas.

    Tunnel for intensive rotting

    The processes of aerobic treatment are normally donetwo-stage. The first treatment step is the intensiverotting, mostly carried out as tunnel composting, withdifferent technical implementations. The main advan-tages are the individual process control of each tunneland independent control of the tunnel heap. The processof tunnel composting is basically characterized by theforced aeration with air circulation to provide an optimalrotting process with an adequate water content of therotting material and an intensive supply with oxygenat a constant heap temperature. Only the self-containedconstruction gives the possibility of specific technicalaeration and central exhaust air collection with subse-quent treatment.

    The second stage of the aerobic treatment is mostlyimplemented as secondary rotting. After the aerobictreatment follows the fine treatment with loadingsystems for the separated contingents.

    Even after the waste incineration not all recycla-bles in the burnt residuals are lost. Especiallyhere it is possible to make the best of the restwith AMB. Processing on a high level of auto-mation is realized by a combination of extrac-tion and separation technique.

    This way it is possible to achieve a constantly good qualityof the different output fractions.

    Main target is a high separation efficiency for recycla-bles and additives for building material. While the metalcontingents can be sold as scrap metal, the remaining slagcontingents in different grains can be used as landfillbuilding material.

    Refuse derived fuel

    Each time when AMB sorting plants producerecyclable fractions or AMB treatment plantsfor residual waste separate the fine fraction forthe biological treatment, rest fractions emerge.Attractive are the high caloric fractions, becauseof the possibility to make refuse derived fuelout of them.

    When the right treatment technology is chosenmultifraction separators separate unwantedmaterials from the leftovers. Ferrous materialand aluminium are separated as recyclables.Materials with PVC can be recognized and iso-lated by optical systems.

    Only from the wanted high caloric materialssingle shaft grinding machines produce RDF,which can be marketed in the adequate par-ticle size.

    PLC control

    Where the quality of recyclables has to be con-trolled manually, the requirements of the work-station are very high. Sorting cabins with bigwindows, sound- and heat-isolated panels andair conditioning make a worker-friendly roomclimate possible.

    The interaction of all components of a sorting andtreatment plant is coordinated by an superior PLCcontrol. Different variations of visualisation on dis-plays or PC make a supervision of the fully- auto-mated operation possible. In the case of breakdownhereby an extensive analysis of the shown messagescan be realised.

    During a reparation period single units can be con-trolled specifically. The documentation of all operat-ing conditions is included as well as a large numberof analysis variations.

    Whether inspection platform or gangway, stairway or support, the steelconstruction is an important part of each AMB sorting and treatmentplant. For each project all plant specificated components are constructed,manufactured and assembled. So a plant becomes more than a amountof there single aggregates.
