High throughput, minimum fines, low operating costs – these were the key factors identified for profitable waste wood processing for combustion purposes that the Austrian shredding expert Lindner Recyclingtech then used to develop their signature mobile system solutions. The company now offers the highly configurable, tried-and-tested Urraco and Miura specialised shredder series that can either be operated as a one-step solution or be combined with a Lindner Zeta Star screen to produce optimum output in line with ISO 17225-1 at unparalleled efficiency.


P100 F05 one step: minimum effort, maximum reward

The newly developed and patented cutting systems of the Urraco 75 and Miura series transform a mobile Lindner shredder into a one-stop system solution for the first time. The two shafts’ optimised geometry and the special breaker bar make it possible to process waste wood in a single step to P100 particles with a fines content of less than 4%. The system combines cutting and crushing in the low speed range, making further processing obsolete.


The mobile hydraulics – likewise a new feature and developed in cooperation with Bosch-Rexroth – ensure a constant throughput of up to 25 metric tons per hour at up to 30% fuel savings compared to conventional solutions. This high performance is made possible thanks to the extreme responsiveness of the 100% electronically controlled system that guarantees the machine’s optimum operation round the clock by proactively adapting to output requirements. Needless to say, Lindner has of course included a mechanical non-shreddable detection system with automatic shaft release for easy removal of foreign objects. This protects the shafts and the drive unit, ensuring a long service life and high productivity.


P63 F05 two steps: old wood, fine product

The combination of a Urraco 75 or Miura 1500 shredder and the Zeta Star 75 F2 star screen means that clean P63 particles can be produced at a throughput of up to 20 metric tons per hour. The perfect synergy of shredder and screen makes this solution a system to reckon with. Efficient production at its best is ensured by the eradication of further screening thanks to an ideal output with under 5% fines. A system that makes loss of valuable material a thing of the past.

With the variable star speed and the hydraulically adjustable screen deck angle, this system can be adapted to varying input qualities at the touch of a button and yields precise and classifiable output at all times. In addition, the hydraulic adjustability of the return conveyor ensures minimum handling effort. Alternatively, oversized particles from the first shredding stage can be separated as a second final fraction.


P100 F05 two steps: when you need that little extra

The combination of Lindner Urraco 95 DK and Zeta Star 95 F2 DK is designed for particularly high throughputs of over 50 metric tons per hour. The perfect match of shredder and screen ensures constant P100 F05 output without material loss thanks to the fines being screened and separated. The shredder’s unbelievable performance and torque of 460,000 newton metres make it easy to process even difficult materials such as railway sleepers with maximum efficiency. Here, too, adapting to changing input qualities is made easy thanks to the self-cleaning screening stars’ variable speed, the particularly low-wear high-performance plastics they are made of and the hydraulically adjustable screen deck angle.
