Old and familiar, redefined

Shredding and screening are the key processing steps needed to turn waste into the desired raw material. As familiar as they may be, Komptech can always find ways to give them a new spin.

High and low speed: Right for their jobs
Komptech offers a notably wide variety of shredding machines to cover any imaginable application. The low-speed dual-shaft Crambo direct has an extra-large shredding chamber with two 2.8 m counterrotating toothed drums that ensure positive feed. From bulky branches and cuttings to rootstocks of any size, to used wood contaminated with contraries, it shreds it all down to a set granular size. The degree of shredding can be adjusted flexibly. 
The mobile Crambo direct is powered by a modern Caterpillar® diesel engine with the latest exhaust scrubbing, and has a drive train that combines the functionality of hydraulic with the efficiency of mechanical drive. That means top economy while retaining all the familiar benefits like overloading protection, reversibility, adaptation to the material, and more. The Crambo is also still available in a pure hydraulic version as well. With a new exterior design, all maintenance can be performed from outside the machine. Easily opened doors give access and fold-out platforms provide safe footing.
The high-speed Axtor universal chipper is one of the most flexible machines there is for processing wood and green cuttings. There is no question that fast chippers are preferred for green cuttings. But the Axtor can do much more. In shredder mode with free-swinging teeth it makes material for composting, while in chipper mode with fixed blades and lower speed it makes biomass fuel for heating plants. Conversion from one mode to another is fast and easy.

Star or drum – it’s the utility that matters
Komptech has a lot to offer in screening as well. The Multistar mobile star screens can split material into up to three fractions in one pass, while at the same time breaking up clumps. What’s more, the operator can change the grain size of the fractions within seconds from the control panel. Easy operation, efficient electric drive with current from a diesel generator or directly from the grid, and additional options like wind sifter, magnet and rock trap make Komptech a star screen technology leader.
Drum screening is a robust, highly functional technology. It can be used for any task, be it biomass, compost or soil production. On Komptech machines the drum can be changed simply and quickly for wide flexibility, while delivering heavy-duty performance under extreme conditions and with difficult materials. Most problems can be dealt with easily by the operator. The technology is tough and proven effective the world over. With the Primus, Maxx, Nemus and the electric-powered Cribus series, Komptech offers a wide range of drum screens that cover any customer requirement.

Not to forget the new Multistar One
The new Multistar One star screen makes treatment of waste wood and biomass even more efficient. It separates out a defined useful fraction while returning overlengths to an upstream shredder like a Crambo or Terminator. With a feed hopper designed for precise material transfer to the generously dimensioned screen deck, a discharge conveyor with four metre discharge height and a return conveyor that can pivot through 220°, the new One delivers a throughput of up to 200 cubic meters per hour. Its very compact crane lift frame and variable conveyors for flexible setup, plus electric drive, make it a highly economical machine.
