Shredding cap timber is quite a challenge for shredding machines. The machine needs to be particularly robust and sturdy. We offer shredding solutions specifically designed for this "very hard" application.

A sturdy and reliable cutting system is required for shredding solid timber. We offer shredding machines that are tested and proven in processing all types of solid timber. 

Our shredders are especially well suited for shredding all types of board materials. Both particle boards and MDF boards are shredded reliably and efficiently. We can always offer a suitable solution depending on the board size and the desired throughput rate and granular size.

UNTHA rotary shears are well proven in the shredding of long wood splinters. Thanks to the special cutting unit configuration, the splinters are independently "pulled" into the machine and reliably shredded. Our rotary shears are particularly sturdy and have a long service life.

Shredding pallets with metal inclusions (nails, screws, clamps, ...) are no problem at all for the robust UNTHA cutting unit. After shredding, the metal pieces can be easily removed with a magnet. We offer customized comprehensive solutions for shredding pallets: From shredding machine and discharge unit to metal separation - all from one source!

When shredding production waste, it is very important for the shredding machines to maintain high availability particularly in multi-shift operation. Our shredders are very reliable and are particularly designed for multi-shift operation. Moreover, the low maintenance requirements further increase availability. 

Shredding thin veneers appears to be very easy at first glance. But correct machine configuration is a decisive factor here. With our spiky shaped pusher infeed system we offer you a customized shredding machine especially designed for shredding veneer. 

Two shredding systems are available for shredding bark. Our rotary shears work especially well with wet bark, while our LR single-shaft series is the preferred system for dry and hard bark.
