Great technology in combination with high reliability at a fair price

The LR630 is a very sturdy wood shredder that is convincing thanks to its technology and expertise. The machine is designed for a long service life and energy efficiency and can be optimally adjusted to your needs. The LR630 is best suited for companies that have a residual timber volume of up to 7 m³ per week.

The LR630 is completely focused on making your work day easier and is one of the most popular models among carpenters. Thanks to its offset rotor bearing, proven and reliable gear damping and special cutting tools, this wood shredder is very low maintenance and has a long service life. This frees up time for what is really important in your company!

The well-designed machine is equipped with a horizontal pusher. The hydraulics aggregate has been placed in the machine housing to save space, where it is also protected from dust and dirt. To protect the wood shredder from possible cutting unit damage, the LR630 is equipped with an automatic foreign objects detection mechanism including automatic shutdown. Added to this is an automatic reverse that prevents motor overload.

Energy efficiency is an important characteristic of the LR630. The proven cutting system ensures the efficient and reliable shredding of your residual timber. The LR630 is available starting with 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 LR630 produces high-quality wood chips 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.

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.
