Our reliable industrial wood shredders and wood grinders ensure the production of a homogeneous granulate. This can be used for your in-house wood chip furnace, biogas plant, biomass co-generation plant and the production of wood briquettes. And this reduction in size also reduces your disposal, transport and storage costs. Regardless of how you are planning to use the wood chips, we will configure the wood grinder or chipper for woodworking scrap exactly according to your needs.
We offer a large selection of longevity wood shredders for carpenters, joineries and the wood processing industries, with various working widths, rotor diameters and drive capacities. The wood waste grinders can shred all mixed woodworking waste such as offcuts, veneers, pallets, solid timber, particleboards and MDF boards. The possible granulate sizes usually range from 12 to 80 mm. Regardless of whether you need a compact, small wood shredder or have specific needs with a conveyer system, we will always find the right wood recycling equipment for you!
Shredding cap timber or off cuts is quite a challenge for wood grinders. 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 wood waste grinders that are tested and proven in processing all types of solid timber
Our single-shaft 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 trouble free size reduction solution depending on the board size and the desired throughput rate and granular size.
UNTHA four-shaft shredders 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 lif
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 woodworking waste from the wood processing industry, it is very important for the shredding machines to maintain high availability particularly in multi-shift operation. Our wood waste grinders 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 wood grinder 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
