The individual percentages were divided according to the mesh size of the sieves into a coarse fraction using a mesh size of 2 mm and 1 mm, a medium coarse fraction with a mesh size of 0.5 mm and 0.250 mm and a fine fraction with a mesh size of 0.125 mm; 0.08 mm; 0.063 mm; 0.032 mm and the bottom of the screening machine, depending on the type of wood and the treatment temperature. When milling oak, the highest proportion of fine particles was recorded at a treatment temperature of 220 °C - 13.18 %. In this way, we can state that the milling showed the effect of a decrease in the mechanical properties of wood with increasing treatment temperature, which is more brittle. The percentage of the finest particles in spruce wood increases with increasing treatment temperature, from 0.53 % in the milling of natural wood to 11.29 % in the milling of heat-treated wood at 220 °C.
