High reliability for many years to come

The reliable and very sturdy RS30 and RS40 industrial wood shredders have been tested and proven over several decades and are used particularly for processing long pieces of timber. These wood chippers can be operated as stand-alone shredders or integrated into complex systems where their very compact design tends to make them a favorite. They are characterized by their high uptime and extremely long cutter life.

The high reliability of this series is a result of the machine's rugged cast-iron frame and sturdy cutting unit. These low-speed, 4-shaft shredders are not sensitive to foreign objects and require very low maintenance. Because they are self feeding, the industrial wood shredder does not need a hydraulic pusher system, further reducing the need for maintenance. The low cutting shaft speed ensures quiet operation and little dust generation in your facility.

The RS30 and RS40 are particularly productive due to their high torque, combined with a large screen area and are a favorite for multi-shift operation. In the event that foreign objects are encountered, the shredder automatically shuts down, minimizing damage. The shredder is also equipped with an automatic reversing system to prevent motor overload.

Four-shaft shredding system

As the innovator of the four-shaft cutting system (patent no. 319535), we have improved these products continuously and adapted them for new markets and applications. Due to their rugged design and high productivity, four-shaft shredders are often used for difficult to shred materials. Thanks to the unique design, both initial and final shredding occurs in just one step.

Accessories

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 auger as well as a screw conveyor. Depending on your application, we will be happy to offer you the right solution in various lengths and inclines.

Shredding wood waste 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 the right pipe magnet to fit your application.

UNTHA offers customized hoppers to fit your needs.  Oversized hoppers to load from a tipper or bucket loader, interlocked access doors, and more, can be accommodated.

Customized substructures offer you maximum flexibility. The wood shredder is thus easily adapted to the on-site conditions and to your existing conveyor technology.
