IFAT 2010: Komptech showcases spectacular new products in the shredding and separation sectors Frohnleiten/ Oelde, August 2010. The objective is clear-cut - by 2020, at least 20 percent of overall European energy consumption must be from renewable energies. The energy recovery of biomass in particular has a key role to play here. However, in order to be able to safeguard the ever increasing demand for biomass in the long term, it is essential to use existing biomass streams more effectively than before and to develop new, reliable energy sources. This is an area in with the mobile and stationary machines of Komptech, the Austro-German specialist in the treatment of solid waste and woody biomass, have been setting benchmarks for many years. Komptech is now demonstrating new, groundbreaking expertise in shredding and separation technology at IFAT 2010, the international trade fair for Water, Waste and Recycling. It is the new general-purpose Axtor 8012 wood shredder, the electrically driven Cribus 2800 drum screen machine and the general-purpose Chippo 5010C chipper that are likely to cause quite a stir. The new Komptech machines are being shown in Hall C2, Stand 403/502, and on the open-air ground of the VDMA “hands-on” days between Halls C2 and C3.

The treatment of waste for material recycling and energy recovery begins with the general-purpose Terminator waste shredder. The Terminator can be used for all types of waste, including bulky refuse, waste wood, building material waste, household waste and commercial waste. The shredder is resistant to contraries and demonstrates its full range of capabilities when tackling waste products such as paper rolls, refrigerators and washing machines. The Terminator has a modern Caterpillar engine as a power source. The complete enclosure of the engine compartment reduces noise emissions down to a minimum. A hydraulic roller drive with load-dependent speed control guarantees optimal utilisation of the engine performance whilst keeping energy efficiency high. The extra large fill hopper is another distinctive feature of the Terminator. The pre-shredder guarantees effective separation of metallic contraries with a hydraulically swivelable overhead magnet or with a magnetic roller on the discharge belt. Komptech offers the contrary-resistant pre-shredder as a mobile and stationary machine with four shredder units. Here U stands for universal, UF for universal-fine, F for fine and XF for extra fine. On Stand 403/502 at IFAT 2010, Komptech is exhibiting the robust, slowrunning single-shaft shredder as a stationary machine with one shredder unit for fine fragmentation (F).

Being held at the same time as IFAT are the VDMA “Biomass treatment” hands-on days in the area outside Hall C2. This is where Komptech is demonstrating in action the general-purpose Chippo 5010 C chipper with direct drive from the lorry, the new Axtor 8012 general-purpose wood shredder with shredder and chip mode and the Multistar L3 star screen with extended coarse screen deck for biomass screening. New to the product range, and on public view for the first time, is the electrically driven Cribus 2800 drum screen machine with a screening area of 28 square metres. In the direct vicinity of the Cribus, Komptech is exhibiting the slow-running, general-purpose Crambo wood shredder with direct drive from the lorry.

The Chippo 5010 C “direct“ is designed as a lorry-mount variant and attains throughputs of up to 220 cubic metres per hour. The mobile chipper is driven by a 484 HP engine. A special transmission system developed specially for this chipper transfers power from the MAN engine to the shredding unit with virtually no loss of power. The active feed system and the hydraulic screen basket exchange system are additional distinguishing features of the Chippo.

As with all members of the Chippo family, the Chippo 5010 C direct has two shredding modes. For shrubbery and smallwood, the continuous feed and a drum speed of 560 rpm provide perfect throughput with correspondingly higher cutting frequency. Saving on power and gentle on the material, the wood chippings generated can be discharged via a conveyor belt, or flexibly and accurately with a blower with adjustable speed. The swivelable conveyor belt is gentle on the material, requires 70% less power and hence improves the cost-effectiveness of wood chip generation.

The general-purpose Axtor 8012 wood shredder from Komptech is being presented for the first time at IFAT. The machine is powered by a 770 HP Caterpillar C18 engine and achieves a throughput rate of up to 300 cubic metres per hour. The Axtor shreds all kinds of wood and offers the user a broad, profitable range of deployment options thanks to its two different operating modes – shredding with free-swinging tool elements and chipping with fixed tool elements.

The Multistar L3 from Komptech is one of the most successful star screen machines on the market.

Hardly any surprise – everything that constitutes modern screen technology is packed within an overall length of 11m. Separation into three fractions is performed in one operation – with wind sifting and Fe separation on request. The Multistar L3 attains a throughput of up to 180 cubic metres per hour (depending on material quality) – enough to keep two wheel loaders constantly busy. The System Cleanstar, developed by Komptech, guarantees a high degree of selectivity even if the starting material has a high residual moisture content. At the same time, the required particle size of the material can be changed within just a few seconds with the speed controller. The seven cubic metre sized hopper on the Multistar L3 and the wide discharge belts satisfy all requirements as regards convenient and economical operation.

With a drum diameter of 2200 millimetres and a total of 28 square metres of screening area, the new Cribus drum screen machine offers the highest screening performance in its class. Thanks to its steep side walls, it is able to take in a multitude of materials and screen them without problem. Even 100 millimetre screen holes are no exception. The power for the electrical drive comes directly from the mains, from an integrated diesel generator or is provided by a separate power generator. The new Wheelgrip drive, developed and patented by Komptech, reduces costs attributable to wear and servicing to an absolute minimum because there are no chains, sprockets or additional bearings.

Compared to diesel-hydraulic drives, the Cribus from Komptech provides savings of up to 75 percent in energy costs, 30 percent in expenditure for wearing parts and 25 percent in operating costs.
