Pfleiderer in Neumarkt Relies on Innovative Recycling Solution from Dieffenbacher

More recycled wood in particleboard production


Using recycled wood in the production of particleboard promises economic benefits as well as increased flexibility when purchasing wood. However,  it also presents challenges, including fluctuations in the type of contamination, the quality, the size and the moisture content of the furnish.


With the help of Dieffenbacher, Pfleiderer in Neumarkt overcomes these challenges with a novel combination of proven screen and sifter technology and a sensor-based X-ray sorting process.


The Dieffenbacher solution provides greater reliability to correct the unavoidable fluctuations in the furnish material and the inherent wide mix of impurities, further optimizing subsequent flake preparation. Thanks to efficient cleaning, the complete material flow can be prepared using known flake technology. Particularly in the preparation of fine materials, emphasis was placed on minimizing wood losses while achieving the required degree of cleanliness in all particle sizes. The concept has also been successful in removing a high proportion of unwanted MDF fibers from the waste wood flow, which has increased plant availability in subsequent processes as well.


When it comes to the secondary size reduction of oversized pieces, Dieffenbacher uses a size reduction system that cuts at a slow speed. In addition to the low specific electricity consumption, the technology is such that only a minimal level of dust is generated by the size reduction. The system operates continuously and has been designed by Dieffenbacher so that it can be integrated into the existing Pfleiderer plant structure very efficiently.


After commissioning of the plant, which is planned for January 2018, Pfleiderer will be able to significantly increase the proportion of recycled wood in the production of particleboard while retaining the same high level of panel quality. This will continue to expand the economic benefits of using recycled wood.
