LR520 wood shredder | UNTHA

Compact and reliable shredding of small residual timber volumes

We designed the LR520 based on the requirements of small companies. This wood shredder is therefore especially compact, reliable and very energy-efficient. The simple and thus low maintenance technology and the extremely small footprint (<1 m²) enable you to efficiently recycle your residual timber. The LR520 is best suited for companies that have a residual timber volume of up to 3 m³ per week.

The wood shredder's reliability comes from its sturdy steel construction and its proven technology. The pusher-free design has a pull-in mechanism and therefore very few moving parts. This reduces maintenance costs to a minimum. The gear damper cushions strong blows during the shredding process and ensures the machine's quiet operation. In addition, the LR520 features a mechanism that detects foreign objects and automatically shuts down the shredder. This prevents damage to the cutting unit.

Energy efficiency plays a big role in the LR520. The proven cutting system can easily shred residual timber and only requires a drive capacity of 11 kW. When it idles for more than 3 minutes, the machine shuts down automatically. This saves energy and simultaneously reduces operating costs.

The LR520 produces high-quality granulate that is well suited for thermal utilisation or briquetting. Each of our wood shredders is customized to your needs. The machines can also be equipped with a metal separator, a conveyor system or a customized hopper. We offer comprehensive solutions from one source!
