Residual timber utilization
Our reliable industrial wood shredders and wood grinders ensure the production of a homogeneous granulate for your in-house wood chip furnace, biogas plant, biomass co-generation plant and the production of wood briquettes. Regardless of how you are planning to use the wood chips, we will configure the wood shredder or chipper exactly according to your needs.
We offer a large selection of longevity wood shredders for carpenters, joineries and the wood working industry, with various working widths, rotor diameters and drive capacities. They can shred all wood waste materials 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 solution for you!
Metal-free wood chips
All our industrial wood shredders produce a high quality granulate for immediate use in wood chip heating systems or the production of briquettes. Metal parts such as nails, screws, clamps or metal fittings are no problem for the cutting system: The metal is shredded together with the waste wood and can easily be removed by an additional metal separation system or a pipe magnet.
