The RS30/40
Robust 4-shaft shredding solutions

The RS30 and RS40 wood shredders are used primarily in the woodworking and timber-processing industries, for instance in sawmills, in solid and laminated timber production facilities, carpentry workshops and joineries. The robustly constructed 4-shaft shredders have proven their worth in wood-shredding applications over several decades and are particularly effective when it comes to shredding solid wood. The shredders may be operated as stand-alone solutions or be integrated in complex plants. They stand out for their high availability and reliable shredding performance and are particularly efficient thanks to their high throughput.


Advantages of the RS30/40

With their compact design, the shredders of the RS series are easy to integrate into production lines, which means that residual wood is automatically fed into the machines and shredded. The chips are then removed via an extraction system. Automating the individual process steps (loading, shredding, extraction) saves time and personnel costs.

The 4-shaft cutting system may be adapted to the respective input material, depending on material density, size and volume. The industrial wood shredders are particularly suitable for the shredding of residual wood such as solid wood, cap pieces, edge trims, veneers, bark, wood with metal inclusions and wet wood.

The shredders also handle large and/or long pieces with ease. Thanks to the automatic material feed of the cutting unit, the machine does not require a hydraulic pusher system, which reduces the service effort required for the shredder.


Maximum availability
Proven wood shredder for multi-shift operation

Thanks to their high torque and large perforated screen surface, the shredders of the RS class are particularly productive, making them perfect partners for intensive continuous operation (multi-shift). In addition, the wood shredders are fitted with an automatic reverse function to prevent motor overload.

Low in maintenance and highly efficient

The low maintenance requirement and the high throughput ensure particularly efficient process flows and thus also low operating costs. In addition, the slow-running 4-shaft machines are highly resistant towards non-shreddables: In case a non-shreddable is detected, the shredder switches off automatically, thus preventing significant damage to the cutting unit and long downtimes.

The reliability of the RS30/RS40 wood shredders also results from their solid steel frame construction and their robust cutting chamber. The low speed of the cutting shafts keeps noise and dust production to a minimum.
