Abstract


This paper presents the results of particle-size distribution of dust created in the milling of selected wood composites, which was carried out using a computer numerical control (CNC) machine. The particle-size distribution was studied through the sieving method and the laser diffraction analysis method. The results of the sieve analysis presented general information about the particle-size distribution of the dust, and the results of laser analysis revealed the content of the finest particles in the whole mass of dust created. The particle size of the dust is subject to the influence of the type of wood composite and the fragmentation degree of wood from which the composites are made. The dust created in milling of fibreboards is characterized by the highest content of the finest particles. It is also 2-3 times higher than in dust from drilling.
