After the wood has been sorted in accordance with the waste wood grades, A1 and A2 waste wood is processed in the first shredder. This slow-speed shredding system shreds pallets, chipboard, demolition and other partially bulky wooden parts with the aim of creating homogenous, well-broken-down material to subsequently separate nails and other metal parts from the material.

The primary shredder’s task is to coarsely shred the material. Especially in the case of bulky wooden panels or large pallets, it must be able to pull in material effectively and autonomously. The large point-to-point square cutters of the JUPITER series run slowly, go easy on the material, are resistant to foreign matter and extremely efficient.

In the second step, a permanent magnet fitted above the conveyor belt is used to safely extract ferromagnetic parts such as nails, scrap iron and other scrap metals.

The pre-shredded waste wood that is free from foreign particles and metals then enters the second shredding stage. The final product should be homogenous and about 15–30 mm in size to ensure that the recycled material is of high quality throughout for the production of chipboard later on.

As a secondary shredder or granulator, a high-speed rotor shredding system is usually used in the final stage due to the material already being ‘clean’. Our high-speed KOMET series with its shear cutters and always precise cut facilitates the highest output rates and constantly high-quality waste wood output.
