Dear readers,

The trend in crude oil pricing over the last 15 months, from approx. 70 to over 140 USD per barrel, and back down to below 100 USD, has dramatically shown us the degree to which the global economy, and further down the line the purchasing power of individual consumers, is dependent upon it. The increase in crude oil pricing, and hence all other energy prices, is the main cause of worldwide inflation. As Alan Greenspan stated in his memoirs published 6 months ago, the current problem in the West is that the global economy is dependent on potentially hostile oil and gas suppliers (OPEC states, Russia, etc.) who are utilising increasing international demand and technological dependency for their own purposes and who are currently amassing untold profits. This is money not available to the Western world (quite apart from the reinvestment of OPEC government bonds by the West), but above all not to consumers. The problem at the current time is therefore clearly attributable to a staged lack of oil production, by OPEC states in particular, and not to a shortage of resources or speculation. Of course resources will be exhausted in the next 20 to 30 years and the exploration of new reserves more difficult to tap will become more expensive, but this is not currently the problem.In addition, the political instability in the Gulf region brings with it massive risk potential. A comparably harmless terror attack on an oil pumping station would have unthinkable consequences for the oil market, not to mention any military conflict between, for example, Iran and Israel. Therefore an awareness process has been initiated across the globe, in the EU in particular, and independently of the climate problem of greenhouse gases caused by fossil fuels, that must put a stop to the dependency on oil and gas, at least on its current scale, so as to gain freedom from this dependency which is intolerable for the global economy. Unfortunately there is considerable resistance from some corners on national level to this plan, formulated in the new proposal for a “Directive on the promotion of energy from renewable sources“ from the EU Commission dated January 23rd 2008. The Austrian position as regards this issue is a scandal. The measures specified in, for example, the amendment of the Austrian Green Electricity Law fall well short of being able to bring about the necessary reversal in the trend. Unfortunately the Austrian industrial lobby, that continues to be characterised by a dinosaur mentality, has a very negative influence on development within Austria in this regard. A positive example here is Sweden. As is generally known, the solution is two-fold – the sourcing of alternative energy forms and a considerably higher level of energy efficiency.

With its overall strategic alignment to the preparation of renewable energy sources made up of

• woody biomass• biogenous waste• refuse derived fuels (from household, residual waste, etc., high in calorific value),

Komptech is of course in tune with this fundamental trend.

But we too must tackle to a greater degree the issue surrounding the energy efficiency of our machines. The specific energy consumption per m³ or ton of treated material for a defined treatment result is becoming more and more of a decision criterion for our customers in making pertinent new investments. This edition therefore puts the focus on this particular issue.

On this note, I trust you enjoy reading this edition.

Yours

Table of contents

The TERMINATOR offers a choice. A machine with hydraulic drive is the better solution where frequently changing material that is difficult to shred is processed. Where the requirement is for constant output, and where the composition of the waste remains largely the same, the decision comes down in favour of the TERMINATOR with direct drive.

Only the most robust of systems survive the harsh everyday environment of a waste treatment plant. Besides the mechanical requirements in terms of long machine service life, it is dust exposure in particular that must be taken into consideration. Space is always at a premium and machines that are low-maintenance and/or are easy to service are likely to enjoy more attention than others.

Rugged systemPower is transferred to a reverse gear/manual transmission unit having two different gears and a high performance clutch, and then on to the drum drive, by a standard asynchronous motor using a maintenance-free Powerband belt system. In terms of resistance to contaminants, this drive has the same functionality as a hydraulic system. If a contrary causes a blockage, a reverse cycle is initiated (as with the hydraulic drive). The cylinder reverses, frees itself and continues to turn in the shredding direction. Even a high number of

blockages within a short space of time does not cause thermal or mechanical damage because cooled, wet-running multi-disc clutches are deployed inside. The drive system is integrated compactly in the machine such that the machine dimensions project only marginally over the dimensions of the shredding area. After opening the side flap, everything is accessible. Servicing work is limited to just gearbox oils and filters. The basic configuration is therefore an operationally reliable system that is not sensitive to dust. A frequency converter is available as an option for infinitely variable regulation of output and for the compensation of reactive current.

The electro-mechanical direct drive mechanism leads to a reduction in specific operating costs (cost per ton of shredded material).Extensive tests in practical operation have shown potential savings up to 40%. This reduction is composed of:

Reduction of energy costsOf particular significance is the reduction in specific energy costs attained as a result of the high efficiency level of the mechanical system.

Less consumables, less servicingSince there are no high performance hydraulic components, servicing and consumables are restricted to auxiliary hydraulic and gear oil.

Lower investmentInvestment costs benefit from a more simple drive system compared to the hydraulic system. The compact unit can be integrated into the process cycle without taking up too much space.

CRAMBO - Universal wood shredder

The savings achieved

Operation in the optimal rotation speed rangeA little less is more - a reduction of the motor rotation speed from 2100 to 1900 brings about a 20% reduction in fuel consumption. Throughput is reduced marginally.Saving on the CRAMBO 5000: 8-12 litres per hour of operation

Always the right programThe green waste program in combination with the damped drive hydraulics improves throughput by 15% whilst reducing consumption at the same time.Increase of throughput on the CRAMBO 5000: 20-30 cubic metres per hour more for green waste

ECO mode – no energy squanderedIn ECO mode, the machine detects an idle state and motor and drum rotation speeds are slowed. Once filling starts again, the machine automatically returns to the operational state set previously. Saving on the CRAMBO 5000: 2-5 litres per hour of operation

The hydraulic drive design of the CRAMBO continues to be the perfect solution for the requirements in the wood and green waste sectors. If, for example, a service provider is working on a contract with a mobile machine, the requirement is to be able to produce a great deal of material within a short space of time and also to be able to shred everything required.This is exactly what the CRAMBO does. Using load-dependent rotation speed regulation, shredding is always performed with the maximum possible drum rotation speed. A mechanical drive generally only knows one rotation speed.

Less is moreA modern Caterpillar diesel motor delivers the power for this. It is right for the highest drum rotation speed to be attained at the highest motor rotation speed. But as field tests demonstrate, a lowering of the motor rotation speed from 2100 to 1900 rpm effects a minimal change in throughput and a 20%

reduction in diesel consumption. The machine hence runs in the “green“ range and the specific consumption is minimal.ECO mode (the self-actuated lowering of the motor rotation speed on idle) makes an important contribution to efficient energy usage.

Reversing as a benefit Reversing shifts the material and cleans drum and screen baskets, improving the shredding process. For tenacious green waste in particular, a new program with shortened reversing times yields an increase in throughput of up to 15%. At the same time, fuel consumption drops by the same amount.This reversing benefit is not implemented on most direct drives.

The bottom line countsTotalling the positives attained from the drive concept of the CRAMBO shows that the machine is difficult to beat in terms of cost-effectiveness.

From waste wood to green waste, from fine to coarse - there is no machine in the wood sector more general-purpose or flexible than the CRAMBO. However, the machine that can do more than all the others need not have a higher fuel consumption. With a few selective alterations, the CRAMBO has become even more fuel-efficient. If the machine is operated in the correct manner, the maximum is gained from every single drop of fuel.

Two years ago, when the first MAXX with electric drive left the factory gates of the competence centre for drum screen technology in Oelde, many were still asking “What is that in aid of?“ Now everybody knows the answer and the competitors are busy imitating.

A new variant of the MAXX and MUSTANG drum screens is available now. On the “E“ variant, electric motors are used in place of hydraulic drives. This saves energy because an electric drive has a markedly higher level of efficiency than a hydraulic system. Power comes directly from the mains or, when required, is produced by an integrated diesel generator. An auxiliary hydraulic system is only used for machine set-up.

Up to 70 percent saving in energy Whilst the MUSTANG hydraulic variant has a 75 kW diesel motor, a diesel generator rated at 48 kVA is sufficient for the MUSTANG E for the same efficiency. The bottom line is a saving in fuel of approx. 25%. Pure mains operation is even more cost-efficient.

With a connected power rating of only 30 kW, energy consumption is approx. 20 kW per hour on average, corresponding to a saving in energy costs of up to 70%. Given the lower servicing overhead and lower quantities of operating resources such as oils and greases, servicing costs for mains operation are more than 40% lower than those of a conventional diesel-hydraulic system.

Flexible deploymentIf power comes from the power socket, no exhaust gases are produced and work can be performed in enclosed halls. This gives rise to a more cost- efficient and, above all, very flexible alternative for stationary projects for which a feed hopper is required. Even higher dust load does not result in clogging of the cooling grate for purely electrical operation. The “E“ variants of the MAXX and MUSTANG are available with and without generator, whereby the generator version also has an optional mains connection. The “removable“ motor unit is also available as an option. With it, it is possible to run the machine inside where no electrical connection is available.

-- Energy costs reduced by 70% -- servicing costs reduced by 30% --

The motor unit is moved out of the machine and placed into a rack frame, together with housing, by a fork-lift truck. This is located in a protected area outside the hall. The distance between motor and drive can be up to 50 metres.

Even easier to operate Thanks to its fully electronic controller, this drive concept features the highest level of ease-of-use. The new display mode shows the operating status and all of the functions are clearly visible and easily configurable. An automatic start-up and ramp unit simplifies start of operation.

Everything proven so successful on the MAXX and MUSTANG of course remains, such as the drum drive using DRUMGRIP. But now the power on the “E“ version comes from an electric motor which is precisely regulated with frequency converters and, in addition, delivers a higher torque to the drum.

For operators who run their screen machines continuously, and who are consequently feeling considerable cost pressure in light of current energy prices, the MAXX E and MUSTANG E are certainly options worth considering because, in this sector, there is scarcely a more efficient way to utilise the energy deployed.

Tailor-made fuelsThe RDF plant in BernburgThe significance of refuse derived fuels (RDF) was recognised early on at the Kreiswerke Delitzsch GmbH (Free state Saxony, D). As one of the first companies to produce a quality-assured refuse derived fuel, we are very well aware of what an RDF plant must be able to do. Mid-2008 saw a new plant commissioned in Bernburg – equipped with machine technology from Komptech.

The plant in Bernburg is capable of producing 60,000 tonnes of premium quality refuse derived fuel annually. Fuel based on customer requirement is the motto here. “We produce tailor-made fuel here that satisfy perfectly the requirements of our customers“, says project leader Frank Dietzel, explaining the design of the plant during a visit by Komptech. “Calorific value, particle size, chemical and physical parameters – everything is fine tuned to the application. This of course does not work when taking any waste and passing it through the plant“, he continues, revealing the recipe for success. “It naturally needs the right ingredients and a great deal of experience. We have gained the latter in abundance in our plant in Delitzsch, in operation since 2000.” Responsible for the ingredients is the Material Flow Management Department which sources raw materials from the marketplace and also sells the products. Carbolight®, the product name, is very well-known within the industry.How this works in prastice becomes apparent when touring the plant. Pre-separation takes place in the delivery area. Production residue from the textile and plastics industries are here processed, sorting residue and

high-calorific fractions from MSW plants. The first step is shredding. A grab crane and a wheel loader determine what the TERMINATOR XF is “fed“. On closer inspection, and with a little fantasy, you could think this as being a kitchen. Both drivers know what is on the menu today. The wheel loader fetches the correct ingredients from the input materials and the grab crane releases it in the correct order, either into the TERMINATOR or, if already pre-shredded, into a metering hopper. “With the XF roller, we get exactly the particle size we need. “Of course the machine has to exert itself sometimes, especially when rolls of carpet or gauze mats are shredded, but it manages everything“. Praise indeed for the TERMINATOR.

Ballistic separationUsing chain conveyors, and via a magnet separation process, it is then off to the next treatment stage, ballistic separation. The BRINI ballistic separator splits the material flow into four fractions. Everything that is heavy, round and hard enters a hopper as heavy fraction and undergoes further shredding. Two different hole sizes in the screen elements give rise to two screen fractions - a fine fraction of 0 - 10 mm, able to be

landfilled due to its high mineral content, and a fraction of 10 - 30 mm which is already fuel. The lightweight fraction is the fourth fraction - flat objects high in calorific value that exit the separator at the upper end and are transported to the post-shredding process. ”I must admit we did have our doubts about the ballistic sifter concept in the planning phase. This scepticism has since been dispelled, indeed the machine has completely impressed us. A major product criterion is the removal of minerals. For fuels blown in under pressure in particular, the mineral fraction can cause abrasive damage. This persistent mineral at the input is removed effectively with intense movement within the separator. Overall the machine works very effectively and requires little space. All of the contaminats dangerous to the post-shredder land safely in the heavy fraction. There are also no complex air ducts, such as for wind sifters, and this of course has a positive effect on operating costs“ – a positive opinion of the BRINI separation technology.Two tried-and-tested Lindner Komet post-shredders are responsible for shredding the lightweight fraction. "The RASOR from Komptech was of interest to us, but when the decision was made, it was not available as we would have needed it. After all, we are a just-in-time supplier", says Dietzel and reveals the subsequent process step, the loading of containers with the finished fuel. Another MULTISTAR star screen is positioned between post-shredder and loading so that particle size matches that required. Overlengths are returned to the post-shredding process.

Fuel with a futureFour loading containers stand in the fully-automatic container loading station. One has just been filled - it is hoisted up by the waiting lorry and transported off to the consumer. The journey is short, just across the road in actual fact, where a large cement works is already awaiting the fuel. “Strategic planning is of course part and parcel of success“, smiles Dietzel,“and the site here is perfect for us. Even more so as a large chemicals company in the direct vicinity is planning its own RDF power station.” Dietzel sees a bright future for refuse derived fuel. Rising energy prices are of course stimulating the market. The cement industry and purpose-built RDF power stations are the prime consumers. It is not certain as to whether all RDF projects in Germany will be realised. The additional payment for the consumer will become lower and lower with increasing demand. Franz Dietzel is convinced:“We are ultimately making huge efforts to produce a quality-assured product which is in a position to replace primary energy – that must be worth something“, continuing, “we do have the right technology for it after all.“

Technology for “Down Under“

At first glance, Australia and green waste composting are not two terms you would associate with one another. But don’t be fooled. Substantial vegetation exists where there is sufficient rainfall or irrigation. A high percentage of green waste from municipal and private landscape conservation is processed into compost. Compost is held in high regard in the country and is used in diversified applications.With suitable products and the right local partner, a country “on the other side of the world“ can become an important market. Despite the vast distances involved, the experienced team at Recycling Technology headed by Nick Fisher always manages to have an ear to the ground at the customer and to establish long-term partnerships through excellent consultancy work and best possible levels of servicing.

Composting as an exampleShredding of the green waste is the starting point. A double-digit number of CRAMBOs is already in the country performing this task in typical CRAMBO style - slow turning without fine fraction production and with incredible flexibility in terms of particle size and material. The hard and sometimes tenacious Australian wood places a heavy burden on the CRAMBO. Apparently the weather is always perfect for working and nowhere else are so many operating hours completed within such a short time.

Triangular windrows are spread far and wide for composting. It is usually not difficult to find a suitable location - conditions here are somewhat different to Europe. Irrigation is important and is implemented with a hose system as on the TOPTURN. This way, large quantities of water can be fed to the thirsty windrow directly from the turning process.The number of screening machines has also risen markedly over recent years. The MUSTANG drum screen machine and, representing star screens, the MULTISTAR L3, are enjoying particular popularity.

ReliabilityAsk which is the most important attribute a machine in Australia must have and you will be met with the reply “reliability”. This reliability is important - firstly because of the often adverse conditions such as sand, dust and high temperatures, and secondly because of the considerable distances that hamper servicing work. A machine in the harsh outback must therefore do its job to the best of its ability for as long as possible. Komptech machines are up to these challenges. Success is measured by satisfied customers and the certainty that another green machine will soon be making its way “down under“.

Als vor zwei Jahren die erste MAXX mit elek-trischen Antrieb die Hallen des Kompetenzzen-trum für Trommelsiebtechnik in Oelde verließ, fragten viele noch: Wozu denn das? Heute kann die Antwort jeder geben und der Mit-bewerb ist eifrig am kopieren.

Ab sofort gibt es bei den Trommelsieben MAXX und MUSTANG eine neue Variante: Bei der E kom-men statt Hydraulikantrieben Elektromotore zum Einsatz. Das spart Energie, denn ein elektrischer Antrieb hat einen deutlich höheren Wirkungs-grad als ein hydraulisches System. Der Strom wird von einem eingebauten Dieselgenerator erzeugt oder kommt direkt vom Netz. Nur für das Einrichten der Maschine wird eine Hilfshydraulik eingesetzt.

Bis zu 70 Prozent Energieersparnis Während die MUSTANG-Hydraulikvariante einen 75 kW Dieselmotor besitzt, reicht der MUSTANG E ein Dieselgenerator mit 48 kVA für die gleiche Arbeitsleistung. Das Resultat ist eine Treibstoffe-insparung um ca. 25 Prozent. Noch günstiger kommt reiner Netzbetrieb: Eine Anschlussleistung von nur 30 kW bedeutet eine Er-sparnis bei den Energiekosten um bis zu 70 Prozent.

STRONG SUCTIONThe new Hurrikan S

Composting would be unthinkable without windsifting. Regardless of whether the screen overflow is re-entered into the composting process or is used as biomass fuel, removal of spurious contaminants (mainly lightweight material such as plastic foils) is a necessity. Nothing masters this job better than the HURRIKAN from Komptech. The secret is the patented pressure-suction process. In the first step, material is separated off by a pressure blower. The material flow transported on to the suction blower is made up of screen residual on top of which lightweight materials have deposited. In the second step, the lightweight material is drawn off by a powerful suction blower. This suction process takes place twice in succession on the HURRIKAN S, increasing throughput and level of selectivity. Configured with the diesel generator, stone trap and magnet drum options, the HURRIKAN becomes the perfect cleaner.

• with high throughputs, over 90% level of selectivity with settings tailored perfectly to material properties

• maximum mobility with 80 km/h chassis and location-independent operation with integrated diesel power unit

• combination possible with virtually any commercially available screen machine

• throughput: HURRIKAN up to 40 m3/h HURRIKAN S up to 60 m3/h

The master of all screens

Stefaan Smet has 16 screen machines in use. Reason enough to ask how he arrives at this figure and whether there is that much to screen in Belgium. We are sitting in a small coffeehouse looking out onto typical Belgian weather outside, i.e. sheets of rain, and Stefaan Smet is taking the time to tell Komptech about his activities. The company Smet R. & Zoonen is a typical family-run business. Founded in 1984 by the family father, operations started with contract work in the agricultural sector. When the sons joined, they brought with them services such as earthmoving, land reclamation and car-park/swimming pool construction. Then, eight years ago, there was a requirement for their own screen machine. "We hired a MAX drum screen for a long time and were extremely satisfied with it", remembers Stefaan Smet. However, the first machine of their own was a step up, namely a MUSTANG. The second machine followed in 2001, the third in 2002 - and then it really took off. The end of 2005 saw the first star screen arrive. Today, Stefaan Smet is the master of 7 MUSTANG drum screens, 4 MULTISTAR L3 star screens and 5 vibrating screens. Windsifting is also offered as a service - a HURRIKAN and a new HURRIKAN S extend the line of machinery in the area of screen technology.

Specialist rental serviceA separate strategy was devised for the rental service. The machines are rented strictly without operator. Machines are passed to customers in excellent condition and not until after thorough training. Should problems arise, a permanent telephone service is available as well as a 4-man technology support team, on-site without a few hours. In addition, a service

Our customers

engineer comes on-site at least once a week to service every screen machine being rent. At the end of the rental period, the machine is inspected jointly with the customer and any necessary maintenance work ascertained. Explaining his reasoning, Stefaan Smet says, "This strategy has borne fruit and renting out machines without personnel brings us financial benefits. This is associated with a certain level of risk of course, but we know the market and the customers. In most cases they have their own machines and personnel and simply need additional screening performance to cover peaks".There are also customers who do not fully utilise their own machines due to the low quantities involved. The customer base also includes local authorities. It is often easier for them to manage a regular service than an investment. In these cases, the company provides machine and operator. A lot of different material is screened. "No matter whether excavated earth, sand, gravel, compost or refuse derived fuels, we can always offer our customers the right screening technology". Stefaan Smet is convinced of this. Custom solutions have also been addressed. "As part of an aluminium recycling process, we had to screen down to 2 mm for the removal of fine dust. We were able to do this with a MUSTANG with segment drum and special screen segments."

Electrical benefitOne of the most recent acquisitions included two MUSTANG E drum screen machines, one with and one without generator. Power is taken from the mains socket wherever possible. Low operating costs of course also benefit the customer. Stefaan Smet can also report on another application. At the port of Gent, pellets are produced from peanut shells. Dust removal with screening is necessary here. However, the dust exposure presented an extreme risk of ignition within the building and so the use of a generator was not a consideration. For this contract, we were able to leverage the new "removable motor unit“ option on the MUSTANG E. We were able to locate the drive unit outside, away from the hazard area, and work continued perfectly smoothly.This specialisation means no problems in capacity utilisation – there is a solution for virtually every screening requirement. Word gets around in the industry and the customer base now includes other companies in Belgium and neighbouring countries.

But it has not only been machine technology convincing Stefaan Smet to remain loyal to a brand. Equally important is the good relationship with the supplier, Pon Equipment - Komptech’s sales partner for Benelux. Both sides have a close and mutually beneficial partnership. For example, Pon Equipment relies on Stefaan Smet as a resource for many of its demonstrations. A demonstration is converted into a rental and often results in a machine sale for the supplier or a long-term rental for the service provider.

But Stefaan Smet has more plans for the future: "The market for biomass in Belgium is still in its early stages and waste treatment for separation of potential recyclables is set to grow further. Here there is still sufficient potential for a service provider with screening technology, in the future perhaps also with shredding technology”. At any rate, we at Komptech are convinced that he will remain loyal to the green machines.

CHIPPO turning up the heat

There is no doubting next winter will arrive. Those heating with wood chips have their heating costs under control. No wonder then that the demand for this stabile-priced fuel is on the up. Consumers are demanding premium quality wood chips with no fine fractions or overlengths. Manufacturers want efficient machines that produce precisely this quality.The CHIPPO 500 makes this requirement a reality. As part of a Roadshow through several European countries, the machine was put through its paces by experts. The result was unequivocal - the CHIPPO is some way ahead of the competition. So the machine not only produces high-quality heating material, it is also turning up the heat on the competition.

CHIPPO 500

15

Neu: Nachzerkleinerer RASOR

15 15

The CHIPPO 500 is a tractor-driven mobile chipper that is just at ease with branches and shrubbery as it is with heavy wood trunks. A glimpse into the feed area reveals all - this is where two horizontal top-mounted and two vertical feed drums greedily await the material. For bulky shrubbery and tree-top wood, this system provides pre-compression and active forwarding into the shredding area.

Chipping the right wayOn the rotor itself, twelve rigid knives with adjustable advance ensure a precise cutting process. The basket can be exchanged without the use of tools and can be extended out whilst working if there is a risk of blockage.

This means damp, matted material can be processed without problem. The load-dependent controller and the rotor speed of 560 rpm mean also that throughput requirements are met.If wood trunks are to be shredded, the rotor speed is set to 400 rpm, automatic start-stop is enabled and soon trunks up to 75 cm in diameter are disappearing into the machine. The drive unit is rated up to 500 HP (360 kW). When this performance is available, volumes in excess of 200 cubic metres exit the machine. Just how is up to the user - either via a blower (with variable speed on request) or via a discharge conveyor belt at the rear of the machine.

Next generation on the horizonThe CHIPPO family is growing. The product range is being extended rapidly and is comparable with the CRAMBO family. So besides classification of drive rating (5000, 6000 and 7000), mobility variants trailer and track will also be available. Lorry-mounted variants will also be available in 2009, one with its own motor and one driven from the towing vehicle.By then it will be difficult for professional wood chipping producers to overlook the CHIPPO.
