Make the best of the rest
We all should contribute to the difficult task of treatingwaste
environmentally compatible and sustainable. Tomatch this demand,
modern waste processing plants areneeded. The state of art allows a
full automatic and highefficient waste sorting and recovery of
reusable materialfrom almost all kinds of solid waste. But only
good ideas,powerful technology and experience make it possible
towork out solutions which get the best out of the rest.
AMB offers what you need. We are producing plants andmachinery
for the waste management and disposal indus-try since 1989, and we
solved every problem until now.Tell us what you want – together we
will get it out.

Solid engineering gets it out
The competence of AMB, the result of yearsof experience in
engineering, concentrateson the core components:
· shredder technology for pre- andsecondary shredding
· separating and mixing technologyfor splitting and preparation
of thewaste streams
· conveyor technology for transportof the different waste
View of a tool shaft
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

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.

· one planetary gear and one hydraulicadjusting motor
· reversing process is controlled byprogrammable logic
· tool system with inserted and weldedtools

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

09Separating and mixing technology ENGINEERING
Interior view of a drum sieve
Stationary drum sieve
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.
· eccentrically mounted, one-piece sieve tub withdifferent mesh
· two drive shafts with one motor each, controlledby frequency
· 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
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.

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

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.
The whole range
of AMB is specialized in sorting and treat-ment plants for
different kinds of waste:
· Light packages· Plastic bottles· Mixed construction and
industrial waste· Cardboard, paper, cardboard packaging· Domestic
and bulk waste· Residual derived fuel· Slag· Organic waste

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
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

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

va-rietal separation in defined raw material sorts. In additionto
the main product deinking, there are mixed paper andvarietal brown

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
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
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
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

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

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.
Assembling of a drum sieve
To deliver components for sorting and treat-ment plants is the
one thing. To design completeturn-key plants, assemble them
professionally,take into operation and attend them until
theacceptance test, is the other thing.
