To obtain fibers, the raw materials are grind and shredded using hammer mills or the biomass shredder BMS, depending on their use. Product qualities differ according to particle size or fiber length. Lignin-protected components can often only be made accessible for material or energy use after appropriate shredding.
Tietjen supplies hammer mills and complete systems for processing shells, stalks, straw or grown wood, whether in a dry state or as fresh wood with a high water content.
