Abstract
Three wood particle types of different origin [knife ring flaker (KRF), hammer mill (HM), sawmill plant] for the manufacture of extruded particleboards were characterized by conventional sieve analysis and image analysis-based particle size measurement. Sieve analysis was performed following two different approaches (on-site, off-site). Image analysis-based measurement was done applying the so-called QICPIC apparatus from Sympatec GmbH (Clausthal-Zellerfeld, Germany). It was found that the size distributions of particles derived from timber production (sawdust) were different in comparison to those of KRF or HM manufacture.
