Wood shredder | UNTHA

Compact and universally applicable wood shredder

The LR700 combines the need for great flexibility with a very compact design. The wood shredder is suitable for companies that want to process up to 12 m³ of residual timber per week. The LR700 single-shaft shredder can be customized depending on what your company needs.

The LR700 is a single-shaft shredder designed for medium throughput and long operating hours. Due to its sophisticated design and swivelling pusher it has a very small footprint. Thanks to the offset rotor bearing, the gear damping and the reliable cutting system, the shredder is very low maintenance and has a long service life. In the event that foreign objects are pushed into the shredder, the smart drive control automatically shuts down the motor. In addition, the shredder is equipped with an automatic reverse to prevent motor overload.

Energy-efficient technology is particularly important for machines designed for more operating hours. This is why the LR700 features the reliable and very efficient cutting system that has been tried and tested a thousand times over. It will shred your residual timber very energy-efficiently even with a low drive capacity. In addition, the motor shuts down automatically if no wood is fed into the machine for more than 3 minutes. This saves energy and simultaneously reduces operating costs.

The LR700 produces high-quality granulate, which is well suited for briquetting or thermal utilisation in wood chip furnaces. 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!

Single-shaft shredding system

Single-shaft shredding systems can be almost universally used and are able to process a broad range of different materials. Depending on the model, they are equipped with a ram system that pushes the material against the rotor with the replaceable cutting inserts. An easily replaced perforated screen defines the desired granulate size.

Our wood shredders come standard with an extraction hood. You can easily connect your existing extraction system to the wood shredder and transport the granulate to the chippings and shavings silo.

Shaftless conveyor spirals are a cost-effective alternative to traditional conveyor screws. The flexible conveyor spirals come in various lengths and diameters. Our technicians will be happy to design a customised solution for your application.

We are also happy to provide infeed and discharge conveyor belts. These will be optimally adapted to the on-site conditions and the desired throughput performance of the shredder.

A popular solution to ensure efficient metal separation is to use conveyor belts equipped with a magnet separator at the pulley. The combination system is a favourite among our customers. UNTHA technicians will be happy to design a customised solution for your application.

Our wood shredders can be equipped with a discharge screw as well as a conveyor screw. Depending on your application, we will be happy to offer you customised solutions in various lengths and inclines.

Shredding residual timber with nails or screws is no problem for our shredders. Pipe magnets are commonly used in extraction situations to separate metal pieces from the wood. We can offer you different pipe magnets depending on your application.

We are able to adapt the hopper exactly to your needs depending on the infeed. Regardless of whether you need a particularly wide hopper for a wheel bearing infeed or a hopper with flip-top lid. We offer customized solutions.
